DA9062
PMIC for applications requiring up to 8.5 A
General Description
DA9062 is a power management integrated circuit (PMIC) optimized for supplying systems with
single- and dual-core processors, I/O, DDR memory, and peripherals. It targets mobile devices,
medical equipment, IVI systems, and FPGA based applications.
DA9062 features four buck converters providing a total current of 8.5 A. High efficiency is achieved
over a wide load range by using automatic Pulse Frequency Modulation (PFM) mode. All power
switches are integrated, therefore, external Schottky diodes are not required. Furthermore, lowprofile inductors can be used with DA9062. Two of the buck converters can be used in a dual-phase
configuration, and one can be used as a DDR VTT supply. The four LDO regulators with
programmable output voltage provide up to 300 mA.
Dynamic Voltage Control (DVC) allows dynamic control of DA9062 supply voltages according to the
2
operating point of the system. It is controlled by writing directly to the registers using the I C
compatible 2-wire interface or the GPIOs.
DA9062 features a programmable power sequencer that handles start-up and shutdown sequences.
Power mode transitions can be triggered with software control, GPIOs, or with the on-key. Several
types of on-key presses can be detected to trigger different power mode transitions.
The Real-Time Clock (RTC), with an external 32 kHz crystal oscillator, provides time keeping and
alarm functions. Additionally, the integrated watchdog timer monitors the system.
Five GPIOs are able to perform system functions, including: keypad supervision, application wakeup,
and timing-controlled external regulators/power switches or other ICs.
DA9062 is also available as an automotive AEC-Q100 Grade 3 version.

7.1
Functional Description
Control Signals
Each of the input signals described below feature a debounce filter. They share a common debounce
time control (DEBOUNCING).
7.1.1
nONKEY
nONKEY is an edge-sensitive signal that controls the power mode of DA9062. Both falling and rising
edges are detected and the time between the edges is measured. This enables different lengths of
key press detection. The detection circuitry is enabled in all power modes of the device.
The status of the signal after debouncing can be read from NONKEY (reg. STATUS_A). The mask
bit M_NONKEY prevents interrupt and wakeup events that would normally be caused by an nONKEY
event.
nONKEY has four modes of operation, see Table 20, which can be selected by NONKEY_PIN.
NONKEY_LOCK controls the wakeup event generation of the nONKEY. If NONKEY_LOCK is
asserted (depends on NONKEY_PIN), a short nONKEY press (shorter than KEY_DELAY) will not
generate a wakeup.
Table 20: nONKEY Functions
NONKEY_PIN
Function
00
An event (E_nONKEY) is generated when nONKEY is asserted. If not masked, the event
causes an interrupt. A wakeup is triggered if the device is in POWERDOWN mode.
01
A timer is started when nONKEY is asserted. If the signal is de-asserted before the time
programmed in KEY_DELAY, an event (E_nONKEY) is generated at the rising edge. If the
signal stays asserted and the timer reaches the programmed value, an event is generated and
nONKEY_LOCK is asserted.
10
A timer is started when nONKEY is asserted. If the signal is de-asserted before the time
programmed in KEY_DELAY, an event (E_nONKEY) is generated at the rising edge. If the
signal stays asserted and the timer reaches the programmed value, an event is generated,
nONKEY_LOCK is asserted, and a power-down sequence is triggered by automatically
clearing SYSTEM_EN.
11
A timer is started when nONKEY is asserted. If the signal is de-asserted before the time
programmed in KEY_DELAY, an event (E_nONKEY) is generated at the rising edge,
SYSTEM_EN is cleared, and STANDBY is asserted. If the signal stays asserted and the timer
reaches the programmed value, an event is generated, nONKEY_LOCK is asserted, and
SYSTEM_EN and STANDBY are cleared.
Whenever nONKEY_LOCK is asserted, a long key press (longer than the time programmed in
KEY_DELAY) is required to wakeup from POWERDOWN mode. If the wakeup is also desired after a
short key press, nONKEY_LOCK has to be cleared before entering the POWERDOWN mode.
7.1.2
nRESETREQ
nRESETREQ is an active-low reset request that causes DA9062 to enter RESET mode. The
transition to the RESET mode is handled by the power sequencer and it can be sped up by setting
the HOST_SD_MODE bit. Before entering the RESET mode, a fault log bit is set (nRESETREQ) and
nRESET is asserted.
nRESETREQ should be tied to an always-on rail that is supplied in all modes of the DA9062 such as
VSYS. It is not recommended to tie nRESETREQ to any of the regulator outputs.

7.1.3
nRESET
nRESET is an active-low reset output intended for resetting the host processor of the system. The
signal can be configured as either push-pull or open drain output (PM_O_TYPE).
nRESET is always asserted upon a cold boot from the no-power mode. It is always asserted at the
beginning of a shutdown sequence to the RESET mode. nRESET may also be asserted at the
beginning of the sequence to the POWERDOWN mode, if configured in control NRES_MODE.
De-assertion of nRESET is controlled by a reset timer. After being asserted, nRESET remains low
until the reset timer, which was started from the selected trigger signal, expires. The reset timer
trigger can be selected via RESET_EVENT and set to one of the following: an external signal
triggering the wakeup (EXT_WAKEUP), an internal signal indicating the end of the first power-up
sub-sequence (SYS_UP), an internal signal indicating the end of the second power-up sub-sequence
(PWR_UP), or the transition of DA9062 from reset to POWERDOWN mode. The expiry time can be
configured via RESET_TIMER from 1 ms to 1 s. If RESET_TIMER is set to 0 ms, nRESET is deasserted immediately after the trigger selected with RESET_EVENT.
7.1.4
nIRQ
nIRQ is a level-sensitive interrupt signal. It can be configured either as a push-pull or an open drain
output (selected via PM_O_TYPE). The polarity of nIRQ can be selected with IRQ_TYPE.
nIRQ is asserted when an unmasked event has occurred. The nIRQ will not be released until all
event registers have been cleared. New events that occur while reading an event register are saved
until the event register is cleared, ensuring that the host processor captures them. The same will
happen to all events occurring when the power sequencer is in transition.
7.2
2-Wire Interface
The 2-wire interface provides access to the control and status registers. The interface supports
2
operations compatible to the standard, fast, fast-plus, and high-speed modes of the I C bus
specification Rev. 3. Communication on the 2-wire bus is always between two devices; one acting as
the master and the other as the slave. The DA9062 only operates as a slave.
SCL transmits 2-wire clock data and SDA transmits the bidirectional data. The 2-wire interface is
open-drain supporting multiple devices on one line. The bus lines have to be pulled high by an
external pull-up resistor (2 kΩ to 20 kΩ). The attached devices drive the bus lines low by connecting
them to ground. As a result, two devices can drive the bus simultaneously without conflict. In
standard/fast mode the highest frequency of the bus is 400 kHz. The exact frequency can be
determined by the application and it does not have any relation to the DA9062 internal clock signals.
DA9062 stays within the described host clock speed limitations and does not initiate clock slowdown. An automatic interface reset is triggered when the clock signal ceases toggling for >35 ms
(controlled in TWOWIRE_TO).
When the SDA is stuck, the bus clears after receiving nine clock pulses. Operation in high-speed
mode at 3.4 MHz requires a minimum interface supply voltage of 1.8 V and a mode change in order
to enable slope-control. The high-speed mode can be enabled on a transfer-by-transfer basis by
sending the master code (0000 1XXX) at the beginning of the transfer. The DA9062 does not make
use of clock stretching and delivers read data without delay up to 3.4 MHz.
Alternatively, the interface can be configured to use high-speed mode continuously via PM_IF_HSM,
so that the master code is not required at the beginning of every transfer. This reduces
communication overhead on the bus and limits the attachable bus slaves to compatible devices.

7.2.1
Register Map Paging
The 2-wire interface has direct access to two pages of the DA9062 register map (up to 256
addresses). The register at address zero on each page is used as a page control register (the LSB of
control PAGE is ignored). Writing to the page control register changes the active page for all
subsequent read/write operations unless an automatic return to page 0 is selected using control
REVERT. Unless REVERT was asserted after modifying the active page, it is recommended to read
back the page control register to ensure that future data exchange is accessing the intended
registers.
DA9062 also offers an alternative way to access register pages which avoids writing explicitly to
PAGE. DA9062 responds to multiple consecutive slave addresses and updates PAGE automatically
based on the slave address. For example, when IF_BASE_ADDR[7:4] = 0xB the slave address
changes PAGE as follows:
Slave address = 0xB0  PAGE = 0x00
Slave address = 0xB2  PAGE = 0x02
7.2.2
Details of the 2-Wire Protocol
All data is transmitted across the 2-wire bus in 8-bit groups. To send a bit, the SDA line is driven at
the intended state while the SCL is low. Once the SDA has settled, the SCL line is brought high and
then low. This pulse on SCL stores the SDA bit in the receiver’s shift register.
A 2-byte serial protocol is used: one address byte and one data byte. Data and address transfer
transmits the MSB first for both read and write operations. All transmissions begin with the START
condition from the master during which the bus is in IDLE state (the bus is free). It is initiated by a
high-to-low transition on the SDA line while the SCL is in high state. A STOP condition is indicated by
a low-to-high transition on the SDA line while the SCL is in high state. The START and STOP
conditions are illustrated in Figure 11.

SCL

Transaction
STOP
Figure 11: Timing of the START and STOP Conditions
DA9062 monitors the 2-wire bus for a valid slave address whenever the interface is enabled. It
responds immediately when it receives its own slave address. This is acknowledged by pulling the
SDA line low during the following clock cycle (white blocks marked with ‘A’ in the following figures).
The protocol for a register write from master to slave consists of a START condition, a slave address,
a read/write-bit, 8-bit address, 8-bit data, and a STOP condition. DA9062 responds to all bytes with
an ACK. A register write operation is illustrated in Figure 12.

When the host reads register data the DA9062 first has to access the target register address with
write access and then with read access and a repeated START, or alternatively a second START,
condition. After receiving the data, the host sends NACK and terminates the transmission with a
STOP condition, see Figure 13.

Figure 13: Examples of Byte Read Operations
Consecutive (page) read-out mode is initiated from the master by sending an ACK instead of NACK
after receiving a byte, see Figure 14. The 2-wire control block then increments the address pointer to
the next register address and sends the data to the master. The data bytes are read continuously
until the master sends a NACK followed by a subsequent STOP condition directly after receiving the
data. If a non-existent 2-wire address is read out then the DA9062 will return code zero.

The slave address after the repeated START condition must be the same as the previous slave
address.
Consecutive (page) write mode is supported if the master sends several data bytes after sending the
register address. The 2-wire control block then increments the address pointer to the next 2-wire
address, stores the received data, and sends an ACK until the master sends a STOP condition. The
page write mode is illustrated in Figure 15.

A repeated write mode can be enabled with WRITE_MODE control. In this mode, the master can
execute back-to-back write operations to non-consecutive addresses by transmitting register
addresses and data pairs. The data is stored in the address specified by the preceding byte. The

configured as disabled in POWERDOWN mode in register PD_DIS (control GPI_DIS). In other
modes, the GPIO is disabled and all ports are configured as open drain outputs in high impedance
state. The level transitions on inputs will no longer be detected, but I/O drivers will keep their

GPI Functionality
In GPI mode, the polarity of the input can be selected with GPIO<x>_TYPE. A debouncing filter can
be applied on the input signals with a configurable debouncing time (control DEBOUNCING). An
event is generated at the active edge of the input. The active edge is determined by the signal
polarity configured in GPIO<x>_TYPE. The event can be further configured to generate a wakeup via
GPIO<x>_WKUP_MODE and GPIO<x>_WEN. An internal pull-down can be activated for the inputs
in GPIO<x>_PUPD.
A level sensitive wakeup event can also be configured for each GPI via GPIO<x>_WKUP_MODE
and GPIO<x>_WEN. The functionality of the level-sensitive wakeup is described in Table 26.
7.3.1.1
Regulator Control
GPIO1, GPIO2, and GPIO3 can be used for controlling DA9062 regulators. When configured as
GPIs, they can be used to enable regulators or select between their two output voltage settings.
As seen in Figure 17, the regulator control is branched after the GPIO<x>_TYPE control allowing
active edge delegation for the regulator control. Finally, the functionality for the GPI is selected with
the regulator controls BUCK<x>_GPI, LDO<x>_GPI, VBUCK<x>_GPI, and VLDO<x>_GPI.
One GPI can be used to control the same function on multiple regulators simultaneously. When a
regulator is controlled by a GPI, the same function (on/off or voltage selection) can no longer be
controlled by the power supply sequencer. The regulator still responds normally to register writes to
the control bit.
Enable/Disable Control
A GPI is used for enabling/disabling regulators when it is selected in one of the BUCK<x>_GPI or
LDO<x>_GPI controls. A passive to active transition sets the regulator enable bit (BUCK<x>_EN,
LDO<x>_EN), and an active to passive transition clears it.
Output Voltage Control
A GPI is used for the output voltage selection when it is selected in one of the VBUCK<x>_GPI or
VLDO<x>_GPI controls. A passive to active transition sets the voltage selection bit
(VBUCK<x>_SEL, VLDO<x>_SEL), and an active to passive edge clears it.
7.3.1.2
Sequencer WAIT_STEP
GPIO3 can be used for the WAIT_STEP functionality. The power sequencer can be programmed to
wait for either a rising or falling edge of the WAIT_STEP input, see Section 7.9.4. The active edge is
selected from GPIO<x>_TYPE.

7.3.2
GPO Functionality
The outputs can be configured as push-pull or open drain outputs, see Table 21. An internal pull-up
can be enabled/disabled from GPIO<x>_PUPD (open drain mode). The GPIO<x>_MODE settings
can control the output state.
Instead of controlling the output with GPIO<x>_MODE, a selection of alternatives is available in the
GPIO<x>_OUT controls. These include: the forwarding function, see Section 7.3.4, the power supply
sequencer, see Section 7.9, the 32 kHz clock (OUT_32K), and the status of the supply voltage
supervision (nVDD_FAULT). When the GPIO is configured as an output and GPIO<x>_OUT is set to
0x0, the GPIO<x>_MODE determines the state of the ouput.
7.3.2.1
nVDD_FAULT
nVDD_FAULT gives the status of the system supply monitoring, see Section 7.11. The assertion of
nVDD_FAULT indicates that the main supply input voltage is low (VSYS < VDD_FAULT_UPPER) and
therefore informs the host processor that the power will soon shut down. It can be configured to drive
a GPO from the GPIO<x>_OUT controls. The driver type (push-pull, open drain) selection and pullup resistor control function normally. The GPIO<x>_MODE can be used to invert the incoming
nVDD_FAULT signal.
7.3.2.2
OUT_32K
OUT_32K feeds a buffered 32 kHz clock signal that is derived from the internal oscillator. The signal
output buffer can be controlled either with the power sequencer or manually via EN_32KOUT, and
paused automatically during POWERDOWN mode with the OUT_32K_PAUSE bit.
Glitch-free switching between a 32 kHz clock output and another GPIO configuration is not
guaranteed. Therefore, configuring a GPIO for 32 kHz clock output should only be done in OTP.
However, enabling and disabling the buffer is still dynamic as described above.
7.3.3
Alternate Functions
GPIO0, GPIO2, and GPIO4 can be used for alternate functions. These are digital control signals that
don’t employ the debouncing, event detection, or interrupt generation functions. Only the input buffer
of the GPIO block is employed. The alternate functions of DA9062 are listed in Table 22 and
described in the following subsections. A debouncing filter can be applied also on the alternate
functions with a configurable debouncing time (control DEBOUNCING).

Asserting SYS_EN causes an interrupt (E_GPIx) and a wakeup event. De-asserting SYS_EN
triggers a power-down sequence but no interrupt.

PWR_EN (pin GPIO2) controls the POWER_EN bit and thereby the power mode of DA9062. It is

generated after assertion of PWR_EN if so configured in GPIO2_WEN.
7.3.3.3
WDKICK
A rising edge of the WDKICK signal resets the watchdog counter. The polarity of the signal can be
chosen in the GPIO0_TYPE control. If the signal is kept asserted, the watchdog is disabled as the
counter is not incremented (WDG_MODE), see Section 7.15.
7.3.4
GPIO Forwarding
GPIO forwarding works between GPIOs 0, 1, 2, and 3. Any of these GPIs can be routed directly to
GPO0, 1, and 3 after debouncing. Forwarding is one of the options for the GPIO<x>_OUT control.
7.3.5

Dynamic Voltage Control
All of DA9062’s buck converters can be controlled in several ways to achieve dynamic voltage
control (DVC). The buck converters feature a voltage ramping feature that enables smooth transition
from one voltage setting to another.
All output voltages can be controlled with software via the 2-wire interface (VBUCK<x>_A). The 2wire interface is operational when the device is in ACTIVE mode.
7.5
Regulator Voltage A And B Selection
In addition, all regulators feature A and B settings which can be programmed with different voltages
(VBUCK<x>_A, VBUCK<x>_B), one of which is chosen according to the operating mode of the
system (VBUCK<x>_SEL, VLDO<x>_SEL). In addition to the output voltage, the A and B settings
include a bit to force the regulator into SLEEP mode which reduces the quiescent current.
The selection between the A and B settings can be done either with software via the 2-wire interface
or by the power sequencer, see Section 7.9. Furthermore, each regulator can be enabled with a GPI
pin, see Section 7.3.1.1, and the selection between the A and B settings done with another GPI.

LDOs
All LDOs employ Dialog Semiconductor’s Smart Mirror™ dynamic biasing technology, see Figure 18,
which maintains high performance over a wide range of operating conditions and a power saving
mode (SLEEP mode) to minimize the quiescent current during very low output current. The circuit
technique offers significantly higher gain bandwidth performance than conventional designs, enabling
higher power supply rejection performance at higher frequencies. PSRR is maintained across the full
operating current range however quiescent current consumption is scaled to demand improved
efficiency when current demand is low.

Voltage Regulator
Control
The LDOs can be enabled by writing directly to a control bit (LDO<x>_EN), controlling it via a GPI,
see Section 7.3.1.1, or assigning it to a power sequencer step, see Section 7.9.2. Each LDO features
two voltage control registers (VLDO<x>_A/VLDO<x>_B) that allow two output voltage preconfigurations. The active setting can then be selected either with a control bit (VLDO<x>_SEL), via
a GPI, see Section 7.3.1.1, or automatically based on the DA9062 power mode. The SLEEP mode of
the LDOs can be linked to either the A or B setting (LDO<x>_SL_A/LDO<x>_SL_B). Therefore, the
LDO will switch to SLEEP mode when the setting is active.
LDO1 differs from the other LDOs because it can be configured as an always-on regulator. This
means that it is also enabled in RESET mode, see Section 7.8.3.
7.6.2
Current Limit
Each LDO provides over-current detection. The current limit is fixed for each LDO based on their
current capability. If any of the LDOs’ current limit is exceeded for longer than 10 ms, an event,
E_LDO_LIM, is triggered. The status of the limit comparator can be observed from LDO<x>_ILIM
(reg. STATUS_D). If an LDO’s current limit is exceeded for longer than 200 ms, the LDO is
automatically disabled. This shutdown feature can be disabled by clearing the LDO_SD control.
Once disabled due to an over-current, the LDO must be re-enabled by one of the sources described
in Section 7.6.1.
7.6.3
Output Pull-Down
When over-voltage (1.06 * VLDO<x>) occurs, the voltage regulators enable an internal load to
discharge the output back to its configured voltage. This feature can be disabled in
LDO<x>_PD_DIS.

7.7
Switching Regulators
DA9062 includes four step-down switching regulators operating at 3 MHz. All switching regulators
employ a synchronous topology with an internal NFET, thus eliminating the need for an external
Schottky diode. The output voltage can be set in 10 mV steps (20 mV steps for Buck3) and the
regulation accuracy is ±3 % over the whole operating temperature range. Static line and load
regulation are also considered in this accuracy.
The switching frequency (3 MHz) is high enough to warrant the use of a small 1.0 µH inductor. The
programming of the converter current limit depends on the coil parameters, as illustrated in Table 24.

Control
The buck can be enabled manually by writing directly to a control register, with an external signal
connected to GPI, see Section 7.3.1.1, or by assigning it to a power sequencer step, see
Section 7.9.2. Each buck converter features two voltage control registers
(VBUCK<x>_A/VBUCK<x>_B) which can be programmed with two different voltages. The active
setting can then be selected via a control bit (VBUCK<x>_SEL), via a GPI, see Section 7.3.1.1, or
automatically based on the power mode of DA9062.
7.7.2
Output Voltage Slewing
To limit in-rush current from the input supply, the buck converters can achieve a new output voltage
with controlled ramping. Ramping is achieved by stepping through all the VBUCK values between the
old and new settings, at a rate defined by SLEW_RATE. The actual output slew rate, in mV/µs, for a
particular buck converter is then defined by the minimum voltage step of that buck and the common
step time programmed in SLEW_RATE. During PFM mode, the negative slew rate is load dependent
and might be lower than the one mentioned above. An event E_DVC_RDY is triggered when all buck
converters have reached their target voltage.
7.7.3
Soft-Start
The buck converter supports two options for starting up. The normal start-up option ramps up the
power rail as fast as possible, typically within 1 ms. This implies a high in-rush current. The slow
start-up is selected by setting BUCK_SLOWSTART, which increases the start-up time and limits the
input current.
7.7.4
Active Discharge
When switching off a buck converter the output rail can be actively discharged. This feature is
enabled by setting BUCK_ACTV_DISCHRG. The discharge is implemented by ramping down the
output voltage using DVC.
7.7.5
Peak Current Limit
All buck converters feature a programmable current limit (BUCK<x>_ILIM). The current limit protects
the inductor and the pass devices from excessive current. If the current limit is exceeded, the buck
continues to run normally but the duty cycle is limited.

7.7.6
Operating Mode
The operating mode of each converter can be set via the buck control (BUCK<x>_MODE) to
synchronous (PWM), sleep (PFM), or auto. In auto mode the buck converter switches between PWM
and PFM depending on the load current. This mode is recommended for applications that require fast
transitions from synchronous to sleep operation. The current consumption during PWM operation is
10 mA and drops to <1 µA in shutdown.
In addition, the buck mode can be controlled with the A and B setting. If BUCK<x>_SL_B is set, the
buck is forced to SLEEP mode when the B setting is active. Similarly, if BUCK<x>_SL_A is set, the
buck is forced to SLEEP mode when the A setting is active.
7.7.7
Half-Current Mode
Buck1 and Buck2 can operate in half-current mode where the quiescent current is reduced by
disabling half of the pass devices. As the name implies, enabling this option halves the output
current, and therefore, this feature is valuable in applications where quiescent current is critical and
full current is not needed. This feature is controlled with BUCK1_FCM and BUCK2_FCM. If the bit is
asserted (BUCK<x>_FCM = 1), the corresponding buck is in full-current mode and the full current is
available. If the bit is de-asserted, the corresponding buck is in half-current mode. Operating the
bucks in full-current mode requires twice as much output capacitance (2 x 47 µF) as the half-current
mode (2 x 22 µF).
7.7.8
Buck1 and Buck2 in Dual-Phase Mode
Buck1 and Buck2 can be merged as a dual-phase buck, with up to 5 A output current. If enabled in
OTP via BUCK1_2_MERGE, the outputs from both inductors must be routed together. The controls
for Buck2 are automatically disabled in this configuration, except for BUCK2_PD_DIS.
7.7.9
Buck4 in DDR Memory Bus Termination Mode
Buck4 can be used to generate the DDR memory termination voltage, VTT. In this mode, Buck4
tracks the divided VDDQ voltage and it is able to both sink and source current. As described in
Section 7.3.5, GPIO0 can be configured to carry the VDDQ and GPIO1 can be configured to carry
the VTTR signal. The VTTR output provides buffered version of the VDDQ/2 voltage with ±10 mA
source/sink capability (requires 0.1 µF stabilisation capacitor), see Figure 19. When used for memory
termination, Buck4 has to be forced in the synchronous (PWM) mode from the BUCK4_MODE
control. If BUCK4_VTT_EN and BUCK4_VTTR_EN are asserted at the same time, the VTTR
provides a buffered VTT reference, but otherwise Buck4 is running in a normal output voltage control
mode.

DA9062
PMIC for applications requiring up to 8.5 A
7.8.1
NO-POWER Mode
The NO-POWER mode is initial state when powering up the DA9062 for the first time. When the
system supply rises above a threshold, DA9062 enters RESET mode.
7.8.2
RTC Mode
The RTC mode is a low-power mode with only a minimum set of functions to maintain the system
time. All supplies are disabled. RTC mode is entered either after a software request or when the
backup battery is the only supply. If enabled in control RTC_MODE_PD, the power sequencer
proceeds automatically from the POWERDOWN state to RTC mode. If the system supply is
removed, DA9062 will also enter RTC mode. Supply recovery will trigger an exit from RTC mode
automatically. DA9062 will exit RTC mode when nONKEY is asserted, or an RTC alarm is raised.
GPIOs are not operational in RTC mode.
7.8.3
RESET Mode
In RESET mode, the internal supplies, and LDO1 (if configured as an always-on supply) are enabled.
All other DA9062 supplies are disabled.
DA9062 is in RESET mode whenever a complete application shutdown is required. RESET mode
can be triggered by the user, a host processor, or an internal event.
RESET mode can be triggered by the user:
● from a long press of nONKEY (interruptible by host) defined by control SHUT_DELAY.
● by pressing a reset switch that is connected to port nRESETREQ (non-interruptible)
RESET mode can be forced from the host processor (non-interruptible):
● by asserting nRESETREQ (falling edge)
● by writing to control SHUTDOWN
DA9062 error conditions that force RESET mode (non-interruptible) are:
● no WATCHDOG write (WDKICK signal assertion) from the host inside the watchdog time window
(if watchdog was enabled)
● an under-voltage detected on VSYS (VSYS < VDD_FAULT_LOWER)
● an internal junction over-temperature
With the INT_SD_MODE, HOST_SD_MODE and KEY_SD_MODE controls, the shutdown
sequences from internal fault, host or user triggered, are individually configured to either implement
the reverse timing of the power-up sequence or transfer immediately to the RESET mode by skipping
any delay from sequencer or dummy slot timers. For the host to determine the reason for the reset a
FAULT_LOG register stores the root cause (either KEY_RESET or NRESETREQ). The host
processor resets this register by writing asserted bits with ‘1’.
KEY_SD_MODE = 1 triggers a complete power on reset (POR) (instead of entering RESET mode)
after the related keys are pressed extendedly.
If an OTP read is aborted, DA9062 enters RESET mode without an asserted bit inside register
FAULT_LOG.
A shutdown sequence to RESET mode will start with the assertion of the nRESET port. After the
sequencer completes the power-down sequence (sequencer position 0), DA9062 continues to
RESET mode with only the following active circuits: LDOCORE (at reduced output voltage 2.2 V),
control interfaces and GPIOs, BCD counter, band-gap and over-temperature/VSYS comparators. All
regulators, except for LDO1 and the backup battery charger, are automatically disabled to avoid
battery drainage. As described in Section 7.1.3, nRESET is always asserted at the beginning of a
shutdown sequence to RESET mode, and remains asserted when DA9062 is in RESET mode.
When entering RESET mode, all user and system events are cleared. The DA9062’s register
configuration will be re-loaded from OTP when leaving the RESET mode (with the exception of
control AUTO_BOOT in case of a VDD_START fault).

DA9062
PMIC for applications requiring up to 8.5 A
FAULT_LOG, GP_ID_10 to GP_ID_19 and other non-OTP loaded registers, for example the RTC
calendar and alarm, will not be changed when leaving the RESET mode.
Some reset conditions such as writing a ‘1’ to control SHUTDOWN, a watchdog error, or a junction
over-temperature will be automatically cleared. Other reset triggers, such as asserting nRESETREQ,
need to be released to proceed from RESET to POWERDOWN mode. If the application requires
regulators to discharge completely before a power-up sequence, a minimum duration of the RESET
mode can be selected via RESET_DURATION.
If the reset was initiated by a user’s long press of nONKEY, initially only KEY_RESET is set and the
nIRQ port will be asserted. KEY_RESET signals the host that a shutdown sequence is started. If the
host does not then clear KEY_RESET within 1 second by writing a ‘1’ to the related bit in register
FAULT_LOG, the shutdown sequence will complete. When the reset condition has disappeared,
DA9062 requires a supply (VSYS > VDD_FAULT_UPPER) that provides enough power to start-up from the
POWERDOWN mode.
RESET mode also allows automatic transition to RTC mode where all features of DA9062, except
the RTC oscillator and calendar (including LDOCORE), are disabled. This mode is selected in control
RTC_MODE_SD.
7.8.4
POWERDOWN Mode
The POWERDOWN mode is a low-power state where most of the regulators are disabled. The
transition from active to POWERDOWN mode (and vice versa) is handled by the programmable
sequencer. Entry to POWERDOWN mode from ACTIVE mode is triggered by the de-assertion of
SYSTEM_EN (either via SYS_EN or register access) or by a short press of nONKEY. The
POWERDOWN mode is also passed during start-up and shutdown to RESET mode sequences.
In POWERDOWN mode the internal supplies are enabled, and the control interface and GPIOs are
operational.
The power state machine features a retry counter that limits the number of transitions from
POWERDOWN to ACTIVE under certain conditions. A watchdog timeout triggers POWERDOWN
mode entry, but it does not necessarily clear the conditions that trigger a transition back to the
ACTIVE mode. This could cause an endless loop between the ACTIVE and POWERDOWN modes.
Therefore, after each watchdog timeout the retry counter is decremented, and after the retry counter
reaches zero, DA9062 blocks all wakeup events and stays in POWERDOWN mode. This freeze
function can be regarded as a substate of the POWERDOWN mode that is undetectable from
outside the DA9062.
Table 26 describes the state transitions with a level-sensitive wakeup and the freeze function.

In this table, “Freeze” represents the result of the comparison retry count = 0.
The following events will reset the retry counter and release the state machine from the freeze state:
● De-assertion of all blocked level-sensitive wakeup conditions
● Entry to the RESET mode (over-temperature error, nRESETREQ or long press of nONKEY)
● Entry to the RTC mode (system supply error)
The freeze operation is illustrated in Figure 21. Once the freeze state is cleared, DA9062 continues
operating normally. The freeze function can be enabled in the FREEZE_EN register and the number
of retries triggering the freeze can be configured in NFREEZE.

Power-Up, Power-Down, and Shutdown Sequences
The power-up, power-down, and shutdown sequences, see Figure 20, are handled by the power
supply sequencer, see Section 7.9. All power-up sequences are identical, and the power-down
sequences mirror the power-up sequences.
The shutdown sequences are also identical to the power-down sequence, but after reaching
POWERDOWN mode, the state machine automatically proceeds to RESET mode. The shutdown
sequences caused by an internal error or nRESETREQ can be sped up from the INT_SD_MODE
and HOST_SD_MODE controls: see Section 7.8.3.
7.8.6
ACTIVE Mode
In the ACTIVE mode, all supplies and functions are active. The transition from POWERDOWN to
ACTIVE mode is handled by the programmable sequencer. DA9062 enters ACTIVE mode after the
sequence has completed and the watchdog is enabled (if configured to use watchdog).
Status information can be read from the host processor via the 2-wire interface and DA9062 can flag
interrupt requests to the host via a dedicated interrupt port (nIRQ).

Power Supply Sequencer
DA9062 features a programmable Power Supply Sequencer that handles the system power-up,
power-down, and shutdown sequences. The sequencer has a step-up counter, a timer that controls
the step period, and a set of comparators that trigger power-on/off events at specific steps of the
counter. The structure of the sequencer is depicted in Figure 22.
The sequencer is composed of 16 steps, and the step time can be programmed between 32 µs and
8.192 ms. The sequencer will step until it reaches a programmable maximum value (MAX_COUNT),
whereupon an interrupt is issued. At each step, the sequencer will enable all the functions that are
pointing to that particular step.
The power-up and -down sequences cannot be configured separately. When DA9062 is powering
down, the sequencer will execute whatever was configured for the power-up sequence but in reverse
order. Supplies can also be configured to stay on in POWERDOWN mode. In this case, the
sequencer does not disable the regulator but switches to its B-configuration, see Section 7.5.
If any pointer is programmed to a step higher than MAX_COUNT, the function is no longer controlled
by the sequencer. Only the regulator control pointers (LDO<x>_STEP, BUCK<x>_STEP) are allowed
to point to step 0. Setting any other pointer to step 0, effectively disables that function.

7.9.1
Sub-Sequences
As illustrated in Figure 22, the sequencer is partitioned into three sub-sequences. These three subsequences can be used to define three power modes for the target application and to move between
them in a controlled sequence as a response to control signals or register writes.
The first sub-sequence starts from step 0 and ends at a step defined by the SYSTEM_END pointer.
After the power-up is triggered, DA9062 performs a partial OTP read (OTP_RD2) if OTPREAD_EN is
set. It then waits for control SYSTEM_EN to trigger the first sub-sequence. If SYSTEM_EN is already
set in the OTP the first sub-sequence starts automatically after the power-up trigger. Alternatively,
SYSTEM_EN can be asserted through the SYS_EN input. When the sequencer reaches the
SYSTEM_END step the first sub-sequence is completed and the sequencer starts waiting for control
POWER_EN to trigger the second sub-sequence. If POWER_EN is already set in the OTP, the
sequencer does not stop after the first sub-sequence. Alternatively, POWER_EN can be asserted
through the PWR_EN input or via a register access.
The second sub-sequence starts from the step following SYSTEM_END and stops at a step defined
by the POWER_END pointer. When the sequencer reaches the POWER_END step (and the
watchdog is active), DA9062 enters ACTIVE mode. The final sub-sequence is triggered by asserting
POWER1_EN via a register write. The third sub-sequence starts from the step following
POWER_END and stops at a step defined by the MAX_COUNT pointer. If MAX_COUNT points to an
earlier step than SYSTEM_END or POWER_END the remaining steps of the sequencer are
disabled.
The power-down sequences are executed in reverse order to the power-up sequences. If the powerdown sequence is triggered from the ACTIVE mode by de-asserting POWER_EN, the sequencer
stops after reversing to the SYSTEM_END step. However, if the power-down sequence is triggered
by de-asserting SYSTEM_EN, the sequencer does not stop and reverses back to step 0.
Furthermore, if the power-down sequence is triggered by a watchdog timeout, the sequencer
reverses to step 0 immediately.
A partial power-down can be achieved by setting control STANDBY. This makes the sequencer stop
at the step pointed to by the PART_DOWN pointer. The next power-up will then start from the
PART_DOWN step, instead of step 0. The PART_DOWN pointer has to point to a step smaller than
the SYSTEM_END pointer.
7.9.2
Regulator Control
Each of DA9062’s buck converters and LDOs can be assigned to any of the sequencer steps. In
general, when the sequencer reaches a step to which a regulator is assigned, that regulator is
enabled by the sequencer. Likewise, when the sequencer reaches the same step on the way down,
the regulator is disabled. Multiple supplies can point to the same counter step, however, enabling
multiple regulators in the same slot can lead to increased in-rush currents.
In the simplest scheme, the sequencer enables regulators during a power-up, and disables them
during a power-down. This functionality is achieved by setting BUCK<x>_AUTO/LDO<x>_AUTO and
clearing BUCK<x>_CONF/LDO<x>_CONF. Alternatively, the sequencer can be configured to keep
the regulator enabled, but switch between the A and B settings in ACTIVE and POWERDOWN
modes. The functionality of the BUCK<x>_AUTO/LDO<x>_AUTO and
BUCK<x>_CONF/LDO<x>_CONF controls is summarized in Table 27.

The regulator stays enabled but it is switched to the
B-setting (VBUCK<x>_B/VLDO<x>_B).
Step 0 of the sequencer has a special meaning. If control DEF_SUPPLY is set, the sequencer treats
all regulators pointing to step 0 as default supplies. This means that the regulators are enabled
automatically when entering the POWERDOWN mode. Regulators assigned to other steps are only
enabled after a wakeup condition occurs. Apart from this, step 0 acts the same as steps 1 to 15. If
control DEF_SUPPLY is ‘0’, step 0 of the sequencer does not have any affect.
As mentioned in Section 7.6.1, LDO1 can be programmed as an always-on supply. This is achieved
by setting controls DEF_SUPPLY, LDO1_CONF, and LDO1_EN in the OTP. In normal operation,
when the sequencer moves between ACTIVE and POWERDOWN modes, LDO1 behaves as
presented in Table 27. However, if DA9062 moves to the RESET mode, this configuration keeps
LDO1 enabled. This is not the case for any other regulator.
7.9.3
GPO Control
Any GPO can be asserted or de-asserted in a sequencer step (GP_RISE<x>_STEP,
GP_FALL<x>_STEP). The GPO control is summarized in Table 28. If a GPO is controlled by the
sequencer, it is driven to its inactive state when DA9062 is in RESET mode. The GPIO control only
works in sequencer steps greater than zero.

7.9.4
Wait Step
One of the sequencer steps (any step greater than zero) can be configured as a wait step, in which
the sequencer stays until an event is detected in the GPI3 input, see Section 7.3.1.2.
Note
The E_GPI3 event has to be cleared after the power-up sequence completes. Otherwise, the wait step in the
next power-up sequence will be ineffective.
The wait step features an optional 500 ms timeout, which can be used when the wait event never
occurs. If the timeout occurs, the steps following the wait step are not executed and a shutdown
sequence to RESET mode is triggered. The shutdown reason is signalled with the WAIT_SHUT bit.
Alternatively, the wait step can be used as a configurable delay in the sequence (WAIT_MODE,
WAIT_TIME).
7.9.5
32 kHz Clock Output
If a GPO is used as a 32 kHz clock output see Section 7.3.2.2, the clock buffer can be
enabled/disabled in one of the sequencer steps (any step greater than zero). The clock buffer is
enabled when, during power-up, the sequencer reaches the step EN32K_STEP. Likewise, the buffer
is disabled when the sequencer reaches the step EN32K_STEP on the way down.
7.9.6
Power-Down Disable
The PD_DIS_STEP pointer can be used to define a step in the power-up sequence above which a
group of functions will be enabled. The functions concerned can be controlled in the PD_DIS register.
Similarly, in the power-down sequence, the same groups of functions will be disabled when the
sequencer proceeds below the PD_DIS_STEP.
7.10 Junction Temperature Supervision
To protect DA9062 from damage due to excessive power dissipation, the junction temperature is
continuously monitored. The monitoring is split into three thresholds TWARN (125 °C), TCRIT (140 °C),
and TPOR (150 °C).
If the junction temperature rises above the first threshold (TWARN), the event E_TEMP is asserted. If
the event is not masked, this will issue an interrupt. This first level of temperature supervision is
intended for non-invasive temperature control, where the necessary measures for cooling the system
down are left to the host software.
If the junction temperature increases even further and crosses the second threshold (T CRIT), the
temperature error flag TEMP_CRIT (in register FAULT_LOG) is issued and a shutdown sequence to
RESET mode is triggered, see Section 7.8.3. The nRESET output is asserted at the beginning of the
shutdown sequence. Therefore, the second level of the temperature supervision does not rely on the
host software to take counter-measures. The fault flag can be evaluated by the application after the
next power-up.
There is also a third temperature threshold (T POR) which causes DA9062 to enter RESET mode
without any sequencing and stop all functions except the RTC. This prevents possible permanent
damage due to fast temperature increases.
7.11 System Supply Voltage Supervision
Two comparators supervise the system supply VSYS. One is monitoring the under-voltage level
(VDD_FAULT_LOWER) and the other is indicating a good system supply (V DD_FAULT_UPPER). The
VDD_FAULT_LOWER threshold is OTP configurable and can be set via the VDD_FAULT_ADJ control from
2.5 V to 3.25 V in 50 mV steps. The VDD_FAULT_UPPER threshold is also OTP configurable and can be
set via the VDD_HYST_ADJ control from 100 mV to 450 mV higher than the VDD_FAULT_LOWER
threshold.
VSYS dropping below the VDD_FAULT_UPPER threshold asserts the event E_VDD_WARN. If the event is
not masked, this will issue an interrupt, which can be used by the host processor as an indication to

decrease its activity. The status can also be signalled with a dedicated nVDD_FAULT signal, see
Section 7.3.2.1.
If VSYS drops below VDD_FAULT_LOWER, the supply error flag VDD_FAULT (in register FAULT_LOG) is
asserted and a shutdown sequence to RESET mode is triggered, see Section 7.8.3. The nRESET
output is asserted at the beginning of the shutdown sequence.
7.12 Backup Battery Charger
The backup battery charger is designed to charge Lithium-Manganese coin cell batteries and super
capacitors. The charger provides a constant charge current with a programmable target voltage. The
charging current is programmable from 100 µA to 1000 µA in 100 µA steps and from 1 mA to 6 mA in
1 mA steps. The end-of-charge termination voltage is programmable in 100/200 mV steps from 1.1 V
to 3.1 V. When enabled, the charger will always keep the backup battery charged at its target
voltage. The backup battery charger can be temporarily disabled in POWERDOWN mode via control
BBAT_DIS.
The backup battery charger includes a reverse current protection and can also be used as an
always-on supply for low-power rails.
The backup battery provides an internal supply voltage for the 32 kHz crystal oscillator and RTC.
7.13 Real-Time Clock (RTC)
The RTC provides a real-time clock and alarm function that can be supplied from the backup battery.
RTC mode is described in Section 7.8.2.
The RTC counter will count the number of 32 kHz clock periods, providing a seconds, minutes,
hours, days, months, and years output. Year 0 corresponds to 2000. It is able to count up to 63
years. The value of the RTC calendar is read- and writeable via the 2-wire interface. A read of
COUNT_S (seconds) saves the current RTC calendar count into registers COUNT_S to COUNT_Y.
Registers are only valid when the RTC_READ status bit is asserted (assertion may take several ms
from leaving POR). After MONITOR has been set, host writing to CRYSTAL and RTC_EN is
prohibited to ensure that the RTC registers SECOND_A to SECOND_D are never stopped.
There is an alarm register containing min, hrs, day, month, and year. When the RTC counter register
value corresponds to the value set in the alarm an interrupt and a wakeup event are generated. The
trigger will also set a bit in an event register to notify that an alarm has occurred. The alarm can
alternatively be asserted from a periodic tick signal that, depending on control TICK_TYPE, is either
asserted every second or minute. After modifying TICK_TYPE or TICK_WAKE, a write to register
ALARM_Y is required to activate the new settings.
The power manager controls, ALARM_ON and TICK_ON, enable/disable the alarm/tick.
The power manager register bit MONITOR is set to 0 each time the RTC is powered up. Software
sets this bit to ‘1’ when setting the time and date, which allows detection of a subsequent loss of the
clock. Values written to the RTC calendar and alarm registers have to comply with the allowed value
range (see register description, for example, less than 60 for seconds or minutes).
7.13.1
32 kHz Crystal Oscillator
The oscillator is used to drive the real time clock (RTC) counter. It works with an external
piezoelectric oscillator crystal at 32 kHz. The oscillator output can be fed to a GPIO and used as a
clock source in the platform. The buffer can be enabled/disabled from a control register or with the
power sequencer.
In order to achieve the desired crystal frequency an external capacitor (10 pF to 20 pF, depending on
the parasitic capacitance of the board) is connected to ground from each of the crystal pins. The
start-up time of the oscillator is typically between 0.5 s and 1 s over the voltage range. When the
crystal is not mounted, the XTAL pins should be grounded.
The oscillator can be enabled from control CRYSTAL. A stabilisation timer can be used to blank the
clock output during the start-up. The timer can be started simultaneously with the oscillator or it can
be configured to wait until the clock’s duty cycle is within the range 30 % to 70 %. The start is

configured from the DELAY_MODE control and the stabilisation time is programmed in the
STABILISATION_TIME control. OUT_CLOCK controls whether the clock feed to the OUT_32K
output (GPIO) is affected by the stabilisation timer. The RTC_CLOCK control provides a similar
gating function for the clock feed to the internal RTC counter.
The clock feed to the OUT_32K output can be controlled with the power sequencer, as described in
Section 7.9.5. In addition, the clock output is one of the features that can be disabled in the
POWERDOWN mode, as described in Section 7.9.6. When the OUT32K_PAUSE control is set, the
clock output is disabled in POWERDOWN.
7.14 Internal Oscillator
An internal oscillator provides a nominal 6.0 MHz clock that is divided to 3.0 MHz for the buck
converters. The frequency of the internal oscillator is adjusted during the initial start-up sequence of
DA9062 to within 5 % of the nominal 6.0 MHz.
Some applications require that the software is able to modify the oscillator frequency at runtime, for
example to avoid interference effects caused by harmonics of the buck converter operating
frequency. This can be achieved by writing a non-zero value to control OSC_FRQ. This control is a
signed 4-bit value where each step changes the frequency by about 1.33 %, which gives a range
from -10.65 % (-8) to +9.33 % (+7).
The tolerance of this frequency will affect most absolute timer values and PWM repetition rates.
7.15 Watchdog
The watchdog provides system monitoring functionality. A watchdog timeout triggers shutdown to
POWERDOWN mode, signalled in register FAULT_LOG. The watchdog can also be configured to
control a secondary reset output in addition to nRESET. This requires that one of the GPIOs is
configured as a GPO, controlled by the sequencer. The assertion/de-assertion is used as a reset,
and the GPIO is configured as a sequencer controlled GPO. This way, after the watchdog triggers
the power-down, the reset output is asserted by the sequencer during the power-down sequence.
Once enabled, the watchdog cannot be stopped and it runs in ACTIVE mode (this feature can be
bypassed with an OTP configuration). The source clock of the watchdog is automatically chosen
between the 32 kHz clock generated from the crystal oscillator and an internally generated slow
frequency clock.
After a cold boot, the watchdog is activated when entering ACTIVE mode. This first watchdog kick is
required for DA9062 to move to the ACTIVE mode after a cold boot, as illustrated in Figure 20. After
the watchdog is activated, the host must kick the watchdog periodically within the watchdog period
programmed with the TWDSCALE control. An interrupt can be generated to warn the host processor
of the watchdog timeout. The time for the warning interrupt is half of the watchdog period.
The kick can be done by a register write to control WATCHDOG (reg. CONTROL_F) or with the
GPIO0 pin configured as a WDKICK input. With control WDG_MODE = 1, the behavior of the
WDKICK input is modified so that either a pulse or a permanently asserted input prevents a
watchdog timeout. In this mode the parameter tWDMIN is not applicable.
If the host processor fails to feed the watchdog, DA9062 asserts a fault bit and enters
POWERDOWN mode. The watchdog timeout can also be configured to assert a reset output. This
requires that one of the GPIOs is configured as a reset output and assigned to a power sequencer
step, see Section 7.9.
After each watchdog timeout a retry counter is decremented. If the retry counter reaches zero,
DA9062 will stay in POWERDOWN mode, as described in Section 7.8.4. The number of allowed
retries can be programmed in the NFREEZE control.

Register Page Control
The device register map is larger than the address range directly addressable from the host
interface. The page control register provides the higher address bits and control for using the paging
mechanism. There are several copies of this register, one per host interface. These copies are
mirrored to addresses 0x080, 0x100 and 0x180.

Application Information
9.1
Component Selection
The following recommended components are examples selected from requirements of a typical
application. The final component selection will be dependent on the specific application. The
electrical characteristics (for example, supported voltage/current range) have to be cross-checked
and component types may need to be adapted from the individual needs of the target circuitry.

Capacitors
Ceramic capacitors are used as bypass capacitors at all VDD and output rails. When selecting a
capacitor, especially ones with high capacitance and small size, the DC bias characteristic has to be
taken into account.
On the VSYS main supply rail, a minimum distributed capacitance of 40 μF (actual capacitance after
voltage and temperature derating) is required.
Buck input capacitors should be within 1.5 mm distance from the supply pin, and the output capacitor
should be close to the inductor.

Inductors
Inductors should be selected based upon the following parameters:
● ISAT specifies the current causing a reduction in the inductance by a specific amount, typically
30 %
● IRMS specifies the current causing a temperature rise of a specific amount
● DC resistance (DCR) is critical for converter efficiency and should be therefore minimized.
● ESR at the buck switching frequency is critical to converter efficiency in PFM mode and should
be therefore minimized.
Inductance is given in Table 32.

Crystal
The real-time clock module requires an external 32.768 kHz crystal. For correct component selection,
the effective load capacitance must to be taken into account. This includes external capacitors on
pins XTAL_IN and XTAL_OUT in series combination, plus the PCB and stray capacitances. For
example, if two 12 pF external capacitors are used, resulting in a total capacitance of 6 pF, and
assuming the stray capacitances are 3 pF, then a crystal that specifies a load capacitance of 9 pF

PMIC for applications requiring up to 8.5 A
9.2.1
General Recommendations
Appropriate trace width and quantity of vias should be used for all power supply paths.
Too high trace resistances can prevent the system from achieving the best performance, for
example, the efficiency and the current ratings of switching converters might be degraded.
Furthermore, the PCB may be exposed to thermal hot spots, which can lead to critical overheating
due to the positive temperature coefficient of copper.
Special care must be taken with the DA9062 pad connections. The traces connecting the pads
should of the same width as the pads and they should become wider as soon as possible.
It is recommended to create a separate quiet ground to which the VREF capacitor, IREF resistor, and
the crystal capacitors are connected. The PCB layout should ensure these component grounds are
kept quiet, that is, they should be separated from the main ground return path for the noisy power
ground. The quiet ground can then be connected to the main ground at the paddle, as shown in
Figure 23.
All traces carrying high discontinuous currents should be kept as short as possible.
Noise sensitive analog signals, such as feedback lines or crystal connections, should be kept away
from traces carrying pulsed analog or digital signals. This can be achieved by separation or shielding
with quiet signals or ground traces.
9.2.2
LDOs and Switched Mode Supplies
The placement of the distributed capacitors on the VSYS rail must ensure that all VDD inputs and
VSYS are connected to a bypass capacitor close to the pad. It is recommended placing at least two
1 µF capacitors close to the VDD_LDOx pads and at least one 10 µF close to the VDD_BUCKx pads.
Using a local power plane underneath the device for VSYS might be considered.
Transient current loops in the area of the switching converters should be minimized.
The common references (IREF, VREF) should be placed close to the device and cross-coupling to
any noisy digital or analog trace must be avoided.
Output capacitors of the LDOs can be placed close to the input pins of the supplied devices (remote
from the DA9062).
Care must be taken with trace routing to ensure that no current is carried on feedback lines of the
buck output voltages (VBUCKx).
The inductor placement is less critical since parasitic inductances have negligible effect.
9.2.3
32 kHz Crystal Oscillator
The crystal and its load capacitors should be placed as close as possible to the IC with short and
symmetrical traces.
The traces must be isolated from noisy signals, especially from clocked digital ones. Ideally the lines
should be buried between two ground layers, surrounded by additional ground traces.
9.2.4
Optimising Thermal Performance
DA9062 features a ground paddle which should be connected with as many vias as possible to the
PCB’s main ground plane in order to achieve good thermal performance.
Solder mask openings for the ball landing pads must be arranged to prohibit solder balls flowing into
vias.
