DESCRIPTION
The TPS65217 is a single chip power management IC specifically designed to support the AM335x series of
application processors in portable and 5-V, non-portable applications. It provides a linear battery charger for
single-cell Li-ion and Li-Polymer batteries, dual-input power path, three step-down converters, four LDOs, and a
high-efficiency boost converter to power two strings of up to 10 LEDs each. The system can be supplied by any
combination of USB port, 5-V AC adaptor, or Li-Ion battery. The device is characterized across a -40°C to
+105°C temperature range which makes it suitable for industrial applications. Three high-efficiency 2.25-MHz
step-down converters are targeted at providing the core voltage, memory, and I/O voltage for a processor based
system.
They enter a low power mode at light load for maximum efficiency across the widest possible range of load
currents. For low-noise applications the devices can be forced into fixed frequency PWM using the I2C interface.
The step-down converters allow the use of small inductors and capacitors to achieve a small solution size.
LDO1 and LDO2 are intended to support system-standby mode. In SLEEP state output current is limited to
100 µA to reduce quiescent current whereas in normal operation they can support up to 100 mA each. LDO3 and
LDO4 can support up to 200 mA each and can be configured as load switches instead of regulators. All four
LDOs have a wide input voltage range that allows them to be supplied either from one of the DCDC converters
or directly from the system voltage node.
By default only LDO1 is always ON but any rail can be configured to remain up in SLEEP state. Especially the
DCDC converters can remain up in a low-power PFM mode to support processor suspend mode.
The TPS65217 offers flexible power-up and power-down sequencing and several house-keeping functions such
as power-good output, pushbutton monitor, hardware reset function and temperature sensor to protect the
battery.
TPS65217A is targeted at the AM335x processor in the ZCE package which does not support DVFS (dynamic
voltage and frequency scaling). In this package, the VDD_MPU and VDD_CORE supplies are shorted together
and require a single power rail only. DCDC1 output voltage is set to 1.8 V to supply DDR2 memory. TPS65217B
is targeted at the AM335x processor in the ZCZ package which supports DVFS and requires dedicated DCDC
converters for VDD_MPU and VDD_CORE rails. DCDC1 output voltage is set to 1.8V to supply DDR2 memories.
TPS65217C is also targeted at the AM335x processor in the ZCZ package, but DCDC1 output voltage is set to
1.5 V to supply DDR3 memories. LDO3 is set to 1.8 V and supports up to 400-mA of current. Please see
Application note SLVU551 for details.
The TPS65217A, TPS65217B and TPS65217C come in a 48-pin leadless package (6-mm x 6-mm QFN) with a
0.4-mm pitch.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

MODES OF OPERATION
OFF
In OFF mode the PMIC is completely shut down with the exception of a few circuits to monitor the AC,
USB, and push-button input. All power rails are turned off and the registers are reset to their default
values. The I2C communication interface is turned off. This is the lowest-power mode of operation. To exit
OFF mode one of the following wake-up events has to occur:
• The push button input is pulled low.
• The USB supply is connected (positive edge).
• The AC adapter is connected (positive edge).
To enter OFF state, set the OFF bit in the STATUS register to ‘1’ and then pull the PWR_EN
pin low. Please note that in normal operation OFF state can only be entered from ACTIVE
state. Whenever a fault occurs during operation such as thermal shutdown, power-good fail,
under voltage lockout, or PWR_EN pin timeout, all power rails are shut-down and the device
goes to OFF state. The device will remain in OFF state until the fault has been removed and
a new power-up event has occurred.
ACTIVE This is the typical mode of operation when the system is up and running. All DCDC converters, LDOs,
load switches, WLED driver, and battery charger are operational and can be controlled through the I2C
interface.
After a wake-up event the PMIC enables all rails not controlled by the sequencer and pulls
the nWAKEUP pin low to signal the event to the host processor. The device will enter
ACTIVE state only if the host asserts the PWR_EN pin within 5 seconds after the wake-up
event. Otherwise it will enter OFF state. In ACTIVE state the sequencer is triggered to bring
up the remaining power rails. The nWAKEUP pin returns to HiZ mode after PWR_EN pin has
been asserted. A timing diagram is shown in Figure 2. ACTIVE state can also be entered
from SLEEP state directly by pulling the PWR_EN pin high. See SLEEP state description for
details.
To exit ACTIVE mode the PWR_EN pin needs to be pulled low.
SLEEP SLEEP state is a low-power mode of operation intended to support system standby. Typically all power
rails are turned off with the exception of LDO1 and the registers are reset to their default values. LDO1
remains operational but can support only limited amount of current (100 µA typical).
To enter SLEEP state, set the OFF bit in the STATUS register to ‘0’ (default) and then pull
the PWR_EN pin low. All power rails controlled by the power-down sequencer will be shut
down and after 1s the device enters SLEEP state. If LDO1 was enabled in ACTIVE state, it
will remain enabled in SLEEP sate. All rails not controlled by the power-down sequencer will
also maintain state. The battery charger will remain active for as long as either USB or AC
supply is connected to the device. Please note that all register values are reset as the device
enters in SLEEP state, including charger parameters.
The device enters ACTIVE state after it detects a wake-up event as described in the
sections above. In addition, the device transitions from SLEEP to ACTIVE state when the
PWR_EN pin is pulled high. This allows the system host to switch the PMIC between
ACTIVE to SLEEP state by control of the PWR_EN pin only.
RESET The TPS65217 can be reset by either pulling the nRESET pin low or holding the PB_IN pin low for more
than 8 seconds. All rails will be shut-down by the sequencer and all register values are reset to their
default values. Rails not controlled by the sequencer are shut down immediately. The device remains in
this state for as long as the reset pin is held low and the nRESET pin must be high to exit RESET state.
However, the device will remain in RESET state for a minimum of 1s before it returns to ACTIVE state. As
described in the ACTIVE section, the PWR_EN pin must be asserted within 5 seconds of nWAKEUP-pinlow to enter ACTIVE state. Please note that the RESET function power-cycles the device and only shuts
down the output rails temporarily. Resetting the device does not lead to OFF state.
If the PB_IN pin is kept low for an extended amount of time, the device will continue to cycle
between ACTIVE and RESET state, entering RESET every 8 s.

WAKE-UP AND POWER UP SEQUENCING
The TPS65217 has a pre-defined power-up / power-down sequence which in a typical application does not need
to be changed. However, it is possible to define custom sequences under I2C control. The power-up sequence is
defined by strobes and delay times. Each output rail is assigned to a strobe to determine the order in which the
rails are enabled and the delay times between strobes are selectable in a range from 1 ms to 10 ms.
NOTE
Although the user can modify the power-up and power-down sequence through the SEQx
registers, those registers are reset to default values when the device enters SLEEP, OFF
or RESET state. In practice this means that the power-up sequence is fixed and a otherthan-default power-down sequence has to be written every time the device is powered up.
Custom power-up/down sequences can be checked out in ACTIVE mode (PWR_EN pin
high) by using the SEQUP and SEQDWN bits. To change the power-up default values,
please contact the factory.
Power-Up Sequencing
When the main power-up sequence is initiated, STROBE1 occurs and any rail assigned to this strobe will be
enabled. After a delay time of DLY1 STROBE2 occurs and the rail assigned to this strobe is powered up. The
sequence continues until all strobes have occurred and all DLYx times have been executed.

The default power-up sequence can be changed by writing to the SEQ1-6 registers. Strobes are assigned to rails
by writing to the SEQ1-4 registers. A rail can be assigned to only one strobe but multiple rails can be assigned to
the same strobe. Delays between strobes are defined in registers SEQ5 and SEQ6.

The power up sequence is executed if one of the following events occurs:
From OFF State:
• Push-button is pressed (falling edge on PB_IN) OR
• USB voltage is asserted (rising edge on USB) OR
• AC adaptor is inserted (rising edge on AC) AND
• PWR_EN pin is asserted (pulled high) AND
• Device is not in Under Voltage Lockout (UVLO) or Over Temperature Shutdown (OTS).
The PWR_EN pin is level sensitive (opposed to edge sensitive) and it makes no difference if it is asserted before
or after the above power-up events. However, it must be asserted within 5 seconds of the power-up event
otherwise the power-down sequence will be triggered and the device enters either OFF state.
From SLEEP State:
• Push-button is pressed (falling edge on PB_IN) OR
• USB voltage is asserted (rising edge on USB) OR
• AC adaptor is inserted (rising edge on AC) AND
• Device is not in Under Voltage Lockout (UVLO) or Over Temperature Shutdown (OTS) OR
• PWR_EN pin is asserted (pulled high).
In SLEEP state the power-up sequence can be triggered by asserting the PWR_EN pin only and the push-button
press or USB/AC assertion are not required.
From ACTIVE State:
The sequencer can be triggered any time by setting the SEQUP bit of the SEQ6 register high. The SEQUP bit is
automatically cleared after the sequencer is done.
Rails that are not assigned to a strobe (SEQ=0000b) are not affected by power-up and power-down sequencing
and will remain in their current ON/OFF state regardless of the sequencer. Any rail can be enabled/disabled at
any time by setting the corresponding enable bit in the ENABLE register with the only exception that the
ENABLE register cannot be accessed while the sequencer is active. Enable bits always reflect the current enable
state of the rail, i.e. the sequencer will set/reset the enable bits for the rails under its control. Also, whenever
faults occur that shut-down the power-rails, the corresponding enable bits will be reset.
Power-Down Sequencing
By default, power-down sequencing follows the reverse power-up sequence. When the power-down sequence is
triggered, STROBE7 occurs first and any rail assigned to STROBE7 will be shut down. After a delay time of
DLY6, STROBE6 occurs and any rail assigned to it will be shut down. The sequence continues until all strobes
have occurred and all DLYx times have been executed.
In some applications it is desired to shut down all rails simultaneously with no delay between rails. Set the
INSTDWN bit in the SEQ6 register to bypass all delay times and shut-down all rails simultaneously when the
power-down sequence is triggered.

A fault occurs in the IC (OTS, UVLO, PGOOD failure).
The PWR_EN pin is not asserted (pulled high) within 5 seconds of a power-up event and the OFF bit is set to

When transitioning from ACTIVE to OFF state, any rail not controlled by the sequencer is shut down after the
power-down sequencer has finished. When transitioning from ACTIVE to SLEEP state any rail not controlled by
the power-down sequencer will maintain state. This allows keeping selected power rails up in SLEEP state.

Special Strobes (STROBE 14 and 15)
STROBE 14 and STORBE 15 are not assigned to the main sequencer but used to control rails that are ‘alwayson’, i.e. are powered up as soon as the device exits OFF state and remain ON in SLEEP state. STROBE 14/15
options are available only for LDO1 and LDO2 and not for any of the other rails.
STROBE 14 occurs as soon as the push-button is pressed or the USB or AC adaptor is connected to the device.
After a delay time of DLY6 STROBE 15 occurs. LDO1 and LDO2 can be assigned to either strobe and therefore
can be powered up in any order (contact factory for details - default settings must be factory programmed since
all registers are reset in SLEEP mode).
When a power-down sequence is initiated, STOBE 15 and STOBE 14 will occur only if the OFF bit is set.
Otherwise both strobes are omitted and LDO1 and LDO2 will maintain state.
POWER GOOD
Power-good is a signal used to indicate if an output rail is in regulation or at fault. Internally, all power-good
signals of the enabled rails are monitored at all times and if any of the signals goes low, a fault is declared. All
PGOOD signals are internally deglitched. When a fault occurs, all output rails are powered down and the device
enters OFF state.
The TPS65217 has two PGOOD outputs, one dedicated to LDO1 and 2 (LDO_PGOOD), and one programmable
output (PGOOD). The following rules apply to both outputs:
• The power-up default state for PGOOD/LDO_PGOOD is low. When all rails are disabled, PGOOD and
LDO_PGOOD outputs are both low.
• Only enabled rails are monitored. Disabled rails are ignored.
• Power-good monitoring of a particular rail starts 5ms after the rail has been enabled. It is continuously
monitored thereafter. This allows the rail to power-up.
• PGOOD and LDO_PGOOD outputs are delayed by the PGDLY (20 ms default) after the sequencer is done.
• If an enabled rail goes down due to a fault (output shorted, OTS, UVLO), PGOOD and/or LDO_PGOOD is
declared low, and all rails are shut-down.
• If the user disables a rail (either manually or through sequencer), it has no effect on the PGOOD or
LDO_PGOOD pin.
• If the user disables all rails (either manually or through sequencer) PGOOD and/or LDO_PGOOD will be
pulled low.

LDO1, LDO2 PGOOD (LDO_PGOOD)
LDO_PGOOD is a push-pull output which is driven to high-level whenever LDO1 and/or LDO2 are enabled and
in regulation. It is pulled low when both LDOs are disabled or at least one is enabled but has encountered a fault.
A typical fault is an output short or over-current condition. In normal operation LDO_PGOOD is high in ACTIVE
and SLEEP state and low in RESET or OFF state.
Main PGOOD (PGOOD)
The main PGOOD pin has similar functionality to the LDO_PGOOD pin except that it monitors DCDC1, DCDC2,
DCDC3, and LS1/LDO3, LS2/LDO4 if they are configured as LDOs. If LS1/LDO3 and/or LS2/LDO4 are
configured as load switches, their respective PGODD status is ignored. In addition, the user can choose to also
monitor LDO1 and LDO2 by setting the LDO1PGM and LDO2PGM bits in the DEFPG register low. By default,
LDO1 and LDO2 PGOOD status does not affect the PGOOD pin (mask bits are set to 1 by default). In normal
operation PGOOD is high in ACTIVE state but low in SLEEP, RESET or OFF state.
In SLEEP mode and WAIT PWR_EN state, PGOOD pin is forced low. PGOOD is pulled high after entering
ACTIVE mode, the power sequencer done, and the PGDLY expired. This function can be disabled by the factory.
Load Switch PGOOD
If either LS1/LDO3 or LS2/LDO4 are configured as load switches their respective PGOOD signal is ignored by
the system. An over-current or short condition will not affect the PGOOD pin or any of the power rails unless the
power dissipation leads to thermal shut-down.

PUSH BUTTON MONITOR (PB_IN)
The TPS65217 has an active-low push-button input which is typically connected to a momentary switch to
ground. The PB_IN input has a 50ms deglitch time and an internal pull-up resistor to an always-on supply. The
push button monitor is used to:
• Power-up the device from OFF or SLEEP mode upon detecting a falling edge on PB_IN.
• Power cycle the device when PB_IN is held low for > 8 s.
Both functions are described in the Modes of Operation section. A change in push-button status (PB_IN
transitions high to low or low to high) is signaled to the host through the PBI interrupt bit in the INT register. The
current status of the interrupt can be checked by reading the PB status bit in the STATUS register. A timing
diagram for the push-button monitor is shown in Figure 5.

nWAKEUP PIN (nWAKEUP)
The nWAKEUP pin is an open drain, active-low output that is used to signal a wakeup event to the system host.
This pin is pulled low whenever the device is in OFF or SLEEP state and detects a wakeup event as described in
the Modes of Operation section. The nWAKEUP pin is delayed 50ms over the power-up event and will remain
low for 50 ms after the PWR_EN pin has been asserted. If the PWR_EN pin is not asserted within 5 seconds of
the power-up event, the device will shut down and enter OFF state. In ACTIVE mode the nWAKEUP pin is
always high. The timing diagram for the nWAKEUP pin is shown in Figure 6.

POWER ENABLE PIN (PWR_EN)
The PWR_EN pin is used to keep the unit in ACTIVE mode once it has detected a wakeup event as described in
the Modes of Operation section. If the PWR_EN pin is not asserted within 5 seconds of the nWAKEUP pin being
pulled low, the device will shut down the power and enter either OFF or SLEEP mode, depending on the OFF bit
in the STATUS register. The PWR_EN pin is level sensitive, meaning that it may be pulled high before the
wakeup event.
The PWR_EN pin may also be used to toggle between ACTIVE and SLEEP mode. See SLEEP mode description
for details.

PB_IN.
RESET PIN (nRESET)
When the nRESET pin is pulled low, all power rails, including LDO1 and LDO2 are powered down and default
register settings are restored. The device will remain powered down as long as the nRESET pin is held low but
for a minimum of 1 second. Once the nRESET pin is pulled high the device enters ACTIVE mode and the default
power-up sequence will execute. See RESET section for more information.
INTERRUPT PIN (nINT)
The interrupt pin is used to signal any event or fault condition to the host processor. Whenever a fault or event
occurs in the IC the corresponding interrupt bit is set in the INT register, and the open-drain output is pulled low.
The nINT pin is released (returns to HiZ state) and fault bits are cleared when the INT register is read by the
host. However, if a failure persists, the corresponding INT bit remains set and the nINT pin is pulled low again
after a maximum of 32 µs.
Interrupt events include pushbutton pressed/released, USB and AC voltage status change.
The MASK bits in the INT register are used to mask events from generating interrupts. The MASK settings affect
the nINT pin only and have no impact on protection and monitor circuits themselves. Note that persisting event
conditions such as ISINK enabled shutdown can cause the nINT pin to be pulled low for an extended period of
time which can keep the host in a loop trying to resolve the interrupt. If this behavior is not desired, set the
corresponding mask bit after receiving the interrupt and keep polling the INT register to see when the event
condition has disappeared. Then unmask the interrupt bit again.

ANALOG MULTIPLEXER
The TPS65217 provides an analog multiplexer that allow access to critical system voltages such as:
• battery voltage (VBAT)
• system voltage (VSYS)
• temperature sense voltage (VTS), and
• VICHARGE, a voltage proportional to the charging current.
In addition one external input is available to monitor an additional system voltage. VBAT and VSYS are divided
down by a factor of 1:3 to be compatible with input voltage range of the ADC that resides on the system host
side. The output of the MUX is buffered and can drive a maximum of 1-mA load current.

BATTERY CHARGER AND POWER PATH
TPS65217 provides a linear charger for Li+ batteries and a triple system-power path targeted at space-limited
portable applications. The power path allows simultaneous and independent charging of the battery and
powering of the system. This feature enables the system to run with a defective or absent battery pack and
allows instant system turn-on even with a totally discharged battery. The input power source for charging the
battery and running the system can be either an AC adapter or a USB port. The power path prioritizes the AC
input over the USB and both over battery input to reduce the number of charge and discharge cycles on the
battery. Charging current is automatically reduced when system load increases and if the system load exceeds
the maximum current of the USB or AC adapter supply, the battery will supplement, meaning that the battery will
be discharged to supply the remaining current. A block diagram of the power path is shown in Figure 8 and an
example of the power path management function is shown in Figure 9.

Figure 9. Power Path Management. In this example the AC input current limit is set to 1300 mA, battery
charge current is 500 mA and system load is 700 mA. As the system load increases to 1000 mA battery
charging current is reduced to 300 mA to maintain AC input current of 1300 mA.
AC and USB supply are detected when the input is 190 mV above the battery voltage and are considered absent
when the voltage difference to the battery is less than 125 mV. This feature ensures that AC and USB supplies
are used whenever possible to save battery life. Since AC is the preferred input it is compared against a 4.1-V
reference for detection when the battery is absent to ensure the power-path switches back to USB when AC is
removed. Other wise the system voltage would drop to 0. USB and AC inputs are both current limited and
controlled through the PPATH register. When either input is not connected to a supply a current source is turned
on to actively discharge the input. The input current sources can also be turned on by the host by setting the
ACSINK and USBSINK bits in the PPATH register.
In case AC or USB are not present or blocked by the power path control logic (e.g. in OFF state), the battery
voltage always supplies the system (VSYS pin).
BATTERY CHARGING
When the charger is enabled (CH_EN bit set to 1) it first checks for a short-circuit on the BAT pin by sourcing a
small current and monitoring the BAT voltage. If the voltage on the BAT pin rises above VBAT(SC), a battery is
present and charging can begin. The battery is charged in three phases: pre-charge, constant current fast charge
(current regulation) and a constant voltage charge (voltage regulation). In all charge phases, an internal control
loop monitors the IC junction temperature and reduces the charge current if an internal temperature threshold is
exceeded. Figure 10 shows a typical charging profile.

Figure 10. LEFT: Typical charge current profile with termination enabled. RIGHT: Modified charging
profile with thermal regulation loop active and termination enabled.
In the pre-charge phase, the battery is charged at a current of IPRECHG which is typically 10% of the fastcharge current rate. The battery voltage starts rising. Once the battery voltage crosses the VLOWV threshold, the
battery is charged at a current of ICHG. The battery voltage continues to rise. When the battery voltage reaches
VOREG, the battery is held at a constant value of VOREG. The battery current now decreases as the battery
approaches full charge. When the battery current reaches ITERM, the TERMI flag in register CHGCONFIG0 is set
to 1. To avoid false termination when the DPM or thermal loop kicks in, termination is disabled when either loop
is active.
The charge current cannot exceed the input current limit of the power path minus the load current on the SYS pin
because the power-path manager will reduce the charge current to support the system load if the input current
limit is exceeded. Whenever the nominal charge current is reduced by action of the power path manger, the DPM
loop, or the thermal loop the safety timer is clocked with half the nominal frequency to extend the charging time
by a factor of 2.
Precharge
The pre-charge current is pre-set to a factor of 10% of the fast-charge current ICHRG[1:0] and cannot be
changed by the user.
Charge Termination
When the charging current drops below the termination threshold (25 mA typical), the charger is turned off.
Charge termination is enabled by default and can be disabled by setting the TERM bit or the CHGCONFIG1
register to 1. When termination is disabled, the device goes through the pre-charge, fast-charge and CV phases,
then remains in the CV phase. The charger behaves like a LDO with an output voltage equal to VOREG, able to
source current up to ICHG or IIN-MAX, whichever is less. Battery detection is not performed.
Battery Detection and Recharge
Whenever the battery voltage falls below VRCH, IBAT(DET) is pulled from the battery for a duration tDET to determine
if the battery has been removed. If the voltage on the BAT pin remains above VLOWV, it indicates that the battery
is still connected. If the charger is enabled (CH_EN = 1), a new battery charging cycle begins.
If the BAT pin voltage falls below VLOWV in the battery detection test, it indicates that the battery has been
removed. The device then checks for battery insertion: it turns on the charging path and sources IPRECHG out of
the BAT pin for duration tDET. If the voltage does not rise above VRCH, it indicates that a battery has been
inserted, and a new charge cycle can begin. If, however, the voltage does rise above VRCH, it is possible that a
fully charged battery has been inserted. To check for this, IBAT(DET) is pulled from the battery for tDET and if the
voltage falls below VLOWV, no battery is present. The battery detection cycle continues until the device detects a
battery or the charger is disabled.

When the battery is removed from the system the charger will also flag a BATTEMP error indicating that the TS
input is not connected to a thermistor.
Safety Timer
The TPS65217 hosts internal safety timer for the pre-charge and fast-charge phases to prevent potential damage
to either the battery or the system. The default fast-charge time can be changed in register CHGCONFIG1 and
the precharge time in CHGCONFIG3. The timer functions can be disabled by resetting the TMR_EN bit of the
CHGCONFIG1 register to 0. Note that both timers are disabled when charge termination is disabled (TERM = 0).
Dynamic Timer Function
Under some circumstances the charger current is reduced to react to changes in the system load or junction
temperature. The two events that can reduce the charging current are:
• The system load current increases, and the DPM loop reduces the available charging current.
• The device has entered thermal regulation because the IC junction temperature has exceeded TJ(REG).
In each of these events, the timer is clocked with half frequency to extend the charger time by a factor of 2 and
charger termination is disabled. Normal operation resumes after IC junction temperature has cooled off and/or
the system load drops to a level where enough current is available to charge the battery at the desired charge
rate. This feature is enabled by default and can be disabled by resetting the DYNTMR bit in the CHGCONFIG2
register to 0. A modified charge cycle with the thermal loop active is shown in Figure 10.
Timer Fault
A timer fault occurs if:
• If the battery voltage does not exceed VLOWV in time tPRECHG during pre-charging.
• If the battery current does not reach ITERM in fast charge before the safetimer expires. Fast-charge time is
measured from the beginning of the fast charge cycle.
The fault status is indicated by CHTOUT and PCHTOUT bits in CHGCONFIG0 register. Timeout faults are
cleared and a new charge cycle is started when either USB or AC supplies are connected (rising edge of VUSB or
VAC), the charger RESET bit is set to 1 in the CHGCONFIG1 register, or the battery voltage drops below the
recharge threshold VRCH.

Battery Pack Temperature Monitoring
The TS pin of the TPS65217 connects to the NTC resistor in the battery pack. During charging, if the resistance
of the NTC indicates that the battery is operating outside the limits of safe operation, charging is suspended and
the safety timer value is frozen. When the battery pack temperature returns to a safe value, charging resumes
with the current timer setting.
By default, the device is setup to support a 10 kΩ the NTC with a B-value of 3480. The NTC is biased through a
7.35-kΩ internal resistor connected to the BYPASS rail (2.25 V) and requires an external 75-kΩ resistor parallel
to the NTC to linearize the temperature response curve.
TPS65217 supports two different temperature ranges for charging, 0°C to 45°C and 0°C to 60°C which can be
selected through the TRANGE bit in register CHCONFIG3.

DCDC CONVERTERS
Operation
The TPS65217 step down converters typically operate with 2.25-MHz fixed frequency pulse width modulation
(PWM) at moderate to heavy load currents. At light load currents the converter automatically enters Power Save
Mode and operates in PFM (Pulse Frequency Modulation).
During PWM operation the converter use a unique fast response voltage mode controller scheme with input
voltage feed-forward to achieve good line and load regulation allowing the use of small ceramic input and output
capacitors. At the beginning of each clock cycle the high-side MOSFET is turned on. The current flows from the
input capacitor via the high-side MOSFET through the inductor to the output capacitor and load. During this
phase, the current ramps up until the PWM comparator trips and the control logic turns off the switch. The
current limit comparator will also turn off the switch in case the current limit of the high-side MOSFET switch is
exceeded. After a dead time preventing shoot through current, the low-side MOSFET rectifier is turned on and
the inductor current ramps down. The current flows now from the inductor to the output capacitor and to the load.
It returns back to the inductor through the low-side MOSFET rectifier.
The next cycle turns off the low-side MOSFET rectifier and turs on the on the high-side MOSFET.
The DC-DC converters operate synchronized to each other, with converter 1 as the master. A 120° phase shift
between DCDC1/DCDC2 and DCDC2/DCDC3 decreases the combined input RMS current at the VIN_DCDCx
pins. Therefore smaller input capacitors can be used.
Output Voltage Setting
The output voltage of the DCDCs can be set in two different ways:
• As a fixed voltage converter where the voltage is defined in register DEFDCDCx.
• An external resistor network. Set the XADJx bit in register DEFDCDCx register and calculate the output
voltage with the following formula:
VOUT = VREF ´ (1 + R1 )
R2
(1)
Where VREF is the feedback voltage of 0.6 V. It is recommended to set the total resistance of R1 + R2 to less
than 1 MΩ. Shield the VDCDC1, VDCDC2, and VDCDC3 lines from switching nodes and inductor L1, L2, and L3
to prevent coupling of noise into the feedback pins.

fixed voltage options programmable through I2C (XADJ3 = 0, default). RIGHT: Voltage is set by external
feedback resistor network (XADJ3 = 1).
Power Save Mode and Pulse Frequency Modulation (PFM)
By default all three DCDC converter enter Pulse Frequency Modulation (PFM) mode at light loads and fixedfrequency Pulse Width Modulation (PWM) mode at heavy loads. In some applications it is desirable to force
PWM operation even at light loads which can be accomplished by setting the PFM_ENx bits in the DEFSLEW
registers to 0 (default setting is 1). In PFM mode the converter skips switching cycles and operates with reduced
frequency with a minimum quiescent current to maintain high efficiency. The converter will position the output
voltage typically +1% above the nominal output voltage. This voltage positioning feature minimizes voltage drops
caused by a sudden load step.
The transition from PWM to PFM mode occurs once the inductor current in the low-side MOSFET switch
becomes 0.

During the Power Save Mode the output voltage is monitored with a PFM comparator. As the output voltage falls
below the PFM comparator threshold of VOUT - 1%, the device starts a PFM current pulse. For this the high-side
MOSFET will turn on and the inductor current ramps up. Then it is turned off and the low-side MOSFET switch
turns on until the inductor current becomes 0 again.
The converter effectively delivers a current to the output capacitor and the load. If the load is below the delivered
current the output voltage will rise. If the output voltage is equal or higher than the PFM comparator threshold,
the device stops switching and enters a sleep mode with typically 15-µA current consumption. In case the output
voltage is still below the PFM comparator threshold, further PFM current pulses will be generated until the PFM
comparator threshold is reached. The converter starts switching again once the output voltage drops below the
PFM comparator threshold.
With a single threshold comparator, the output voltage ripple during PFM mode operation can be kept very small.
The ripple voltage depends on the PFM comparator delay, the size of the output capacitor and the inductor
value. Increasing output capacitor values and/or inductor values will minimize the output ripple.
The PFM mode is left and PWM mode entered in case the output current can no longer be supported in PFM
mode or if the output voltage falls below a second threshold, called PFM comparator low threshold. This PFM
comparator low threshold is set to -1% below nominal VOUT, and enables a fast transition from Power Save Mode
to PWM Mode during a load step.
The Power Save Mode can be disabled through the I2C interface for each of the step-down converters
independent from each other. If Power Save Mode is disabled, the converter will then operate in fixed PWM
mode.
Dynamic Voltage Positioning
This feature reduces the voltage under/overshoots at load steps from light to heavy load and vice versa. It is
active in Power Save Mode. It provides more headroom for both the voltage drop at a load step, and the voltage
increase at a load throw-off. This improves load transient behavior. At light loads, in which the converter operates
in PFM mode, the output voltage is regulated typically 1% higher than the nominal value. In case of a load
transient from light load to heavy load, the output voltage drops until it reaches the PFM comparator low
threshold set to –1% below the nominal value and enters PWM mode. During a load throw off from heavy load to
light load, the voltage overshoot is also minimized due to active regulation turning on the low-side MOSFET.

100% Duty Cycle Low Dropout Operation
The device starts to enter 100% duty cycle Mode once the input voltage comes close the nominal output voltage.
In order to maintain the output voltage, the high-side MOSFET is turned on 100% for one or more cycles. As VIN
decreases further, the high-side MOSFET is turned on completely. In this case the converter offers a low inputto-output voltage difference. This is particularly useful in battery-powered applications to achieve longest
operation time by taking full advantage of the whole battery voltage range.

The minimum input voltage to maintain regulation depends on the load current and output voltage, and can be
calculated as:
VIN , MIN = VOUT , MAX + I OUT , MAX × (RDSON , MAX + RL )
(2)
where:
IOUT,MAX = Maximum output current plus inductor ripple current
RDSON,MAX = Maximum upper MOSFETt switch RDSON
RL = DC resistance of the inductor
VOUT,MAX = Nominal output voltage plus maximum output voltage tolerance
Short-Circuit Protection
High-side and low-side MOSFET switches are short-circuit protected. Once the high-side MOSFET switch
reaches its current limit, it is turned off and the low-sideMOSFET switch is turned ON. The high-side MOSFET
switch can only turn on again, once the current in the low-sideMOSFET switch decreases below its current limit.
Soft Start
The 3 step-down converters in TPS65217 have an internal soft start circuit that controls the ramp up of the
output voltage. The output voltage ramps up from 5% to 95% of its nominal value within 750 µs. This limits the
inrush current in the converter during start up and prevents possible input voltage drops when a battery or high
impedance power source is used. The soft start circuit is enabled after the start up time tStart has expired.

Inductor Selection for Buck Converters
The step-down converters operate typically with 2.2-µH output inductors. Larger or smaller inductor values can
be used to optimize the performance of the device for specific operation conditions. The selected inductor has to
be rated for its DC resistance and saturation current. The DC resistance of the inductance will influence directly
the efficiency of the converter. Therefore an inductor with lowest DC resistance should be selected for highest
efficiency.
The following formula can be used to calculate the maximum inductor current under static load conditions. The
saturation current of the inductor should be rated higher than the maximum inductor current because during
heavy load transient the inductor current will rise above the calculated value.

The highest inductor current will occur at maximum VIN. Open core inductors have a soft saturation characteristic
and they can usually handle higher inductor currents versus a comparable shielded inductor.
A more conservative approach is to select the inductor current rating just for the maximum switch current of the
corresponding converter. It must be considered, that the core material from inductor to inductor differs and will
have an impact on the efficiency especially at high switching frequencies. Also the resistance of the windings will
greatly affect the converter efficiency at high load. Please refer to Table 1 for recommended inductors.

Output Capacitor Selection
The advanced Fast Response voltage mode control scheme of the two converters allow the use of small ceramic
capacitors with a typical value of 10 µF, without having large output voltage under and overshoots during heavy
load transients. Ceramic capacitors having low ESR values result in lowest output voltage ripple and are
therefore recommended.
If ceramic output capacitors are used, the capacitor RMS ripple current rating must always meet the application
requirements. For completeness the RMS ripple current is calculated as:

Because of the nature of the buck converter having a pulsating input current, a low ESR input capacitor is
required for best input voltage filtering and minimizing the interference with other circuits caused by high input
voltage spikes. The converters need a ceramic input capacitor of 10 µF. The input capacitor can be increased
without any limit for better input voltage filtering. Please refer to Table 2 for recommended ceramic capacitors.

STANDBY LDOS (LDO1, LDO2)
LDO1 and LDO2 support up to 100 mA each, are internally current limited and have a maximum drop-out voltage
of 200 mV at rated output current. In SLEEP mode, however, output current is limited to 100 µA each. When
disabled, both outputs are discharged to ground through a 300-Ω resistor.
LDO1 supports an output voltage range of 1.0 V - 1.8 V which is controlled through the DEFLDO1 register. LDO2
supports an output voltage range from 0.9 V - 1.5 V and is controlled through the DEFLDO2 register. By default,
LDO1 is enabled immediately after a power-up event as described in the Modes of Operation section and
remains ON in SLEEP mode to support system standby. Each LDO has low standby-current of < 15 µA typical.
LDO2 can be configured to track the output voltage of DCDC3 (core voltage). When the TRACK bit is set in the
DEFLDO2 register, the output is determined by the DCDC3[5:0] bits of the DEFDCDC3 register and the
LDO2[5:0] bits of the DEFLDO2 register are ignored.
LDO1 and LDO2 can be controlled through STROBE 1-6, special STROBES 14 and 15, or through the
corresponding enable bits in the ENABLE register. By default, LDO1 are controlled through STROBE15 which
keeps it alive in SLEEP mode. The STROBE assignments can be changed by the user while in ACTIVE mode
but be aware that all register settings are reset to default values in SLEEP or OFF mode. This can cause the
LDO to power up automatically when leaving SLEEP mode even tough they have been disabled in SLEEP mode
previously by assigning them to a different strobe or resetting the corresponding enable bit. If this is not desired,
new default values must be programmed into non-volatile memory by the factory. Contact TI for details.
LOAD SWITCHES/LDOS (LS1/LDO3, LS2/LDO4)
TPS65217 provides two general-purpose load switches that can also be configured as LDOs. As LDOs they
support up to 200 mA each, are internally current limited and have a maximum drop-out voltage of 200 mV at
rated output current. LDO3 and LDO4 of the TPS65217C device supports up to 400-mA of current. In either
mode ON/OFF state can be controlled either through the sequencer or the LS1_EN and LS2_EN bits of the
ENABLE register. When disabled, both outputs are discharged to ground through a 300-Ω resistor.
As load switches LS1 and LS2 have a max impedance of 650 mΩ. Different from LDO operation, load switches
can remain in current limit indefinitely without affecting the internal power-good signal or affecting the other rails.
Please note, however, that excessive power dissipation in the switches may cause thermal shutdown of the IC.
Load switch and LDO mode are controlled by LS1LDO3 and LS2LDO4 bits of the DEFLS1 and DEFLS2
registers.
WHITE LED DRIVER
TPS65217 contains a boost converter and two current sinks capable of driving up to 2 x 10 LEDs at 25 mA or a
single string at 50 mA of current. The current per current sink is approximated by the following equation:
I LED = 1048´
1.24V
RSET
(7)
Two different current levels can be programmed using two external RSET resistors. Only one current setting is
active at any given time and both current sinks are always regulated to the same current. The active current
setting is selected through the ISEL bit of the WLEDCTRL1 register.
Brightness dimming is supported by an internal PWM signal and I2C control. Both current sources are controlled
together and cannot operate independently. By default, the PWM frequency is set to 200 Hz, but can be changed
to 100 Hz, 500 Hz, and 1000 Hz. The PWM duty cycle can be adjusted from 1% (default) to 100% in 1% steps
through the WLEDCTRL2 register.
When the ISINK_EN bit of WLEDCTRL1 register is set to 1, both current sinks are enabled and the boost output
voltage at the FB_WLED pin is regulated to support the same ISINK current through each current sink. The boost
output voltage, however, is internally limited to 39 V.
If only a single WLED string is required, short ISINK1 and ISINK2 pins together and connect them to the Cathode
of the diode string. Note that the LED current in this case is 2 x ISINK.

BATTERY-LESS/5-V OPERATION
TPS65217 provides a linear charger for Li+ batteries but the IC can operate without a battery attached. There are
three basic use-cases for battery-less operation:
1. The system is designed for battery operation, but the battery is not inserted. The system can be powered by
connecting an AC adaptor or USB supply.
2. A non-portable system running off a (regulated) 5-V supply, but the PMIC must provide protection against
input over-voltage up to 20 V. Electrically this is the same as the previous case where the IC is powered off
an AC adaptor. The battery pins (BAT, BATSENSE, TS) are floating and power is provided through the AC
pin. DCDC converters, WLED driver, and LDOs connect to the over-voltage protected SYS pins. Load
switches (or LDO3 and LDO4, depending on configuration) typically connect to one of the lower system rails
but may also be connected to the SYS pin.
3. A non-portable system running of a regulated 5-V supply that does not require input-over-voltage protection.
In this case the 5-V power supply is connected through the BAT pins and the DCDC converter inputs, WLED
driver, LDO1, and LDO2 are connected directly to the 5-V supply. A 10-kΩ resistor is connected from TS to
ground to simulate the NTC of the battery. Load switches (or LDO3 and LDO4, depending on configuration)
typically connect to one of the lower system rails, but may also be connected to the 5-V input supply directly.
The main advantage of connecting the supply to the BAT pins is higher power-efficiency because the internal
power-path is by-passed and power-loss across the internal switches is avoided.
Figure 18 shows the connection of the input power supply to the IC for 5-V only operation with and without 20-V
input over-voltage protection and Table 5 lists the functional differences between both setups.

DCDC input current passes through AC-SYS
power-path switch (approximately 150 mΩ).
Internal power-path is bypassed to minimize IxR
losses.
BATTEMP bit
BATTEMP bit (bit 0 in register 0x03h) always
reads 1, but has no effect on operation of the

BATTEMP bit (bit 0 in register 0x03h) always reads
0.
Output rail status upon initial
power connection
LDO1 is automatically powered up when AC pin
is connected to 5-V supply and device enters
[WAIT PWR_EN] state. IF PWR_EN pin is not
asserted within 5s, LDO1 turns OFF.
LDO1 is OFF when BAT is connected to 5-V supply.
PB_IN must be pulled low to enter [WAIT PWR_EN]
state.
Response to input-over-voltage
Device enters OFF mode.
NOTE: If a battery is present in the system,
TPS65217 automatically switches from AC to
BAT supply when AC input exceeds 6.5 V and
back to AC when AC input recovers to safe
operating voltage range.

SLVSB64D – NOVEMBER 2011 – REVISED APRIL 2012
The I2C Bus is a communications link between a controller and a series of slave terminals. The link is established
using a two-wired bus consisting of a serial clock signal (SCL) and a serial data signal (SDA). The serial clock is
sourced from the controller in all cases where the serial data line is bi-directional for data communication
between the controller and the slave terminals. Each device has an open Drain output to transmit data on the
serial data line. An external pull-up resistor must be placed on the serial data line to pull the drain output high
during data transmission.
Data transmission is initiated with a start bit from the controller as shown in Figure 21. The start condition is
recognized when the SDA line transitions from high to low during the high portion of the SCL signal. Upon
reception of a start bit, the device will receive serial data on the SDA input and check for valid address and
control information. If the appropriate group and address bits are set for the device, then the device will issue an
acknowledge pulse and prepare the receive of sub-address data. Sub-address data is decoded and responded
to as per the “Register Map” section of this document. Data transmission is completed by either the reception of
a stop condition or the reception of the data word sent to the device. A stop condition is recognized as a low to
high transition of the SDA input during the high portion of the SCL signal. All other transitions of the SDA line
must occur during the low portion of the SCL signal. An acknowledge is issued after the reception of valid
address, sub-address and data words. The I2C interfaces will auto-sequence through register addresses, so that
multiple data words can be sent for a given I2C transmission. Reference Figure 20 and Figure 21 for detail.

PASSWORD PROTECTION
Registers 0x0B through 0x1F with exception of the password register are protected against accidental write by a
8-bit password. The password needs to be written prior to writing to a protected register and is automatically
reset to 0x00h after the following I2C transaction, regardless of the register that was accessed and regardless of
the transaction type (read or write). The password is required for write access only and is not required for read
access.
Level1 Protection
To write to a Level1 protected register:
1. Write the address of the destination register, XORed with the protection password (0x7Dh) to the
PASSWORD register.
2. Write data to the password protected register.
3. Only if the content of the PASSWORD register XORed with the address send in step 2 matches 0x7Dh, the
data will be transferred to the protected register. Otherwise the transaction will be ignored. In any case the
PASSWORD register is reset to 0x00 after the transaction.
The cycle needs to be repeated for any other register that is Level1 write protected.

Level2 Protection
To write to a Level2 protected register:
1. Write the address of the destination register, XORed with the protection password (0x7Dh) to the
PASSWORD register.
2. Write to the password protected register. The register value will not change at this point but the data will be
temporarily stored if the content of the PASSWORD register XORed with the address send in step 2 matches
0x7Dh. In any case, the PASSWORD register is reset to 0x00 after the transaction.
3. Write the address of the destination register, XORed with the protection password (0x7Dh) to the
PASSWORD register.
4. Write the same data as in step 2 to the password protected register. Again, the content of the PASSWORD
register XORed with the address send in step 4 must match 0x7Dh for the data to be valid.
5. The register will be updated only if both data transfers 2, and 4 were valid, and the transferred data matched.
Note that no other I2C transaction is allowed between step 2 and 4 and the register will not be updated if any
other transaction occurs in-between. The cycle needs to be repeated for any other register that is Level2 write
protected.

0 – DCDC converter operates in PWM / PFM mode, depending on load
1 – DCDC converter is forced into fixed frequency PWM mode
PFM enable bit, DCDC2
PFM_EN2
0 – DCDC converter operates in PWM / PFM mode, depending on load
1 – DCDC converter is forced into fixed frequency PWM mode
PFM enable bit, DCDC3
PFM_EN3
0 – DCDC converter operates in PWM / PFM mode, depending on load
1 – DCDC converter is forced into fixed frequency PWM mode

Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability
information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that
lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between
the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight
in homogeneous material)
