Smart High-side Switch Module
(Triple 6.0 mOhm and Dual
17 mOhm)
06XS3517
The 06XS3517 device is a five channel 12 V high-side switch module with
integrated control and a high number of protective and diagnostic
functions. It is designed for automotive lighting and industrial applications.
The low RDS(on) channels (three 6.0 mOhm, two 17 mOhm) can control
different types of lighting applications; bulbs, Xenon-HID lights, and LEDs.
Control, device configuration, and diagnostics are performed through a
16-bit SPI interface (3.3 V or 5.0 V). When communication with the
external microcontroller or VDD is lost, the device enters a fail-safe
operation mode, but remains operational, controllable, and protected.
The channels are controlled by an external clock signal and allow
staggered switch-on delay, to improve EMC performances. Programmable
output voltage slew rates (individually programmable) further help improve
EMC performance. To avoid shutting off the device upon inrush current
while still being able to closely track the load current, a dynamic
overcurrent threshold profile is featured. Load current in each channel can
be sensed. The duty cycle of the channels can be controlled independently
and the switching frequency of each of them can be doubled. The
06XS3517 is housed in a non-leaded Power QFN package with an
exposed pad. This device is powered using SMARTMOS technology.

FUNCTIONAL DESCRIPTION
INTRODUCTION
FUNCTIONAL DESCRIPTION
INTRODUCTION
The 06XS3517 is designed for low-voltage automotive and
industrial lighting applications. Its five low RDS(on) MOSFETs
(three 6.0 mOhm and two 16 mOhm) can control the high-
sides of five separate resistive loads (bulbs). Programming,
control, and diagnostics are accomplished using a 16-bit SPI
interface.
FUNCTIONAL PIN DESCRIPTION
SUPPLY VOLTAGE (VBAT)
The VBAT pin of the 06XS3517 is the power supply of the
device. In addition to its supply function, this tab contributes
to the thermal behavior of the device by conducting the heat
from the switching MOSFETs to the printed circuit board.
SUPPLY VOLTAGE (VCC)
The timing includes four programmable PWM switching
phases (0°, 90°, 180°, and 270°) to improve overall EMC
behavior of the light module.
As an example: When the load currents have equal
amplitude, the amplitude of the input current is divided by
four, while the ripple frequency is 4 times the original. The two
following pictures illustrate this behavior.
This is an external voltage input pin used to supply the
digital portion of the circuit and the gate driver of the external
smart MOSFET.
GROUND (GND)
This pin is the ground of the device.
CLOCK INPUT / WAKE-UP OUTPUT (CLOCK)
When the part is in Normal mode (RST=1), the PWM
frequency and timing are generated from the rising edge of
clock input by the PWM module. The clock input frequency is
the selectable factor 27 = 128 or 28 = 256 of the PWM
frequency per output, depending PR bit value.
The OUT1:6 can be controlled in the range of 4% to 96%
with a resolution of 7 bits of the duty cycle (bits D[6:0]).
Figure 6 describes the PWM resolution.

• With the following SPI configuration: D7:D0=FF.
• In case of clock input signal failure (out of f PWM), the
outputs state depends of D7 bit value (D7 = 1 = ON) in
Normal mode.
In Fail mode, the ouputs state depend on IGN, FLASHER,
and FOG pins.
The synchronization of the switching phases between
different IC is provided by a SPI command in combination
with the CSB input. The bit in the SPI is called PWM sync
(initialization register).
In Normal mode, no PWM feature (100% duty cycle) is
provided in the following instances:
If RSTB = 0, this pin reports the wake-up event for wake=1
when VBAT and VCC are in operational voltage range.
LIMP HOME INPUT (LIMP)
The Fail mode of the component can be activated by this
digital input port. The signal is “high active”, meaning the Fail
mode can be activated by a logic high signal at the input.

Freescale Semiconductor
FUNCTIONAL DESCRIPTION
FUNCTIONAL PIN DESCRIPTION
IGNITION INPUT (IGN)
FET OUT OUTPUT (FETOUT)
The ignition input wakes the device. It also controls the Fail
mode activation. The signal is “high active”, meaning the
component is active in case of a logic high at the input.
This output pin can be used to control an external smart
MOSFET (OUT6) at a logic level (1 = ON, 0 = OFF).
The high level of the FETOUT Output is VCC, if VBAT and
VCC are available, in case FETOUT is a controlled ON.
FETOUT is not protected if there is a short-circuit or
undervoltage on VBAT.
In case of a reverse battery, OUT6 is OFF.
FLASHER INPUT (FLASHER)
The flasher input wakes the device. It also controls the Fail
Mode activation. The signal is “high active”, meaning the
component is active in case of a logic high at the input.
FOG INPUT (FOG)
The fog input wakes the device. It also controls the Fail
Mode activation. The signal is “high active”, meaning the
component is active in case of a logic high at the input.
RESET INPUT (RSTB)
This input wakes the device when the RSTB pin is at
logic [1]. It is also used to initialize the device configuration
and the SPI faults registers when the signal is low. All SI/SO
registers described Table 9 and Table 12 are reset. The fault
management is not affected by RSTB (see Figure 2).
CURRENT SENSE OUTPUT (CSNS)
The current sense output pin is an analog current output or
a voltage proportional to the temperature on the GND flag.
The routing to the external resistor is SPI programmable.
This current sense monitoring may be synchronized in
case of the OUT6 is not used. The CSNS output is valid after
a rising edge on the FETOUT pin (after tsync(val) s.) if the
CSNS sync SPI bit was set to logic [0] and remains valid till a
falling edge is generated. Connection of the FETOUT pin to
a MCU input pin allows the MCU to sample the CSNS pin
during a valid time slot. Since this falling edge is generated at
the end of this time slot, upon a switch-off command, this
feature may be used to implement maximum current control.
CHARGE PUMP (CP)
An external capacitor must be connected between the CP
and the VBAT pin. It is used as a tank for the internal charge
pump. Its value is 100 nF ± 20%, 25 V maximum.
FET IN INPUT (FETIN)
This input pin receives the current recopy from an external
smart MOSFET. It can be routed on CSNS output by a SPI
command.
SPI PROTOCOL DESCRIPTION
The SPI interface has a full-duplex, three-wire,
synchronous data transfer with four I/O lines associated with
it: Serial Clock (SCLK), Serial Input (SI), Serial Output (SO),
and Chip Select (CSB).
The SI/SO pins of the 06XS3517 device follow a first-in,
first-out (D15 to D0) protocol, with both input and output
words transferring the most significant bit (MSB) first. All
inputs are compatible with 3.3 V and 5.0 V CMOS logic
levels, supplied by VCC.
The SPI lines perform the following functions:
SERIAL CLOCK (SCLK)
The SCLK pin clocks the internal shift registers of the
06XS3517 device. The SI pin accepts data into the input shift
register on the falling edge of the SCLK signal, while the SO
pin shifts data information out of the SO line driver on the
rising edge of the SCLK signal. It is important that the SCLK
pin be in a logic low state whenever CSB makes any
transition. For this reason, it is recommended the SCLK pin
be in a logic [0] whenever the device is not accessed (CSB
logic [1] state). SCLK has a passive pull-down, RDWN. When
CSB is logic [1], signals at the SCLK and SI pins are ignored,
and SO is tri-stated (high-impedance) (see Figure 8).

Figure 8. Single 16-Bit Word SPI Communication
SERIAL INPUT (SI)
CHIP SELECT (CS)
The SI pin is a serial interface command data input pin.
Each SI bit is read on the falling edge of SCLK. A 16-bit
stream of serial data is required on the SI pin, starting with
D15 to D0. SI has a passive pull-down, RDOWN.
The CSB pin enables communication with the master
device. When this pin is in a logic [0] state, the device is
capable of transferring information to, and receiving
information from, the master device. The 06XS3517 device
latches in data from the Input Shift registers to the addressed
registers on the rising edge of CSB. The device transfers
status information from the power output to the Shift register
on the falling edge of CSB. The SO output driver is enabled
when CSB is logic [0]. CSB should transition from a logic [1]
to a logic [0] state only when SCLK is a logic [0]. CSB has a
passive pull-up, RUP.
SERIAL OUTPUT (SO)
The SO data pin is a tri-stateable output from the shift
register. The SO pin remains in a high-impedance state until
the CSB pin is put into a logic [0] state. The SO data is
capable of reporting the status of the output, the device
configuration, and the state of the key inputs. The SO pin
changes state on the rising edge of SCLK and reads out on
the falling edge of SCLK.

SLEEP MODE
The Sleep mode is the default mode of the 06XS3517.
This is the state of the device after first applying battery
voltage (VBAT) and prior to any I/O transitions. This is also the
state of the device when IGN, FOG, FLASHER, and RSTB
are logic [0] (wake = 0). In the Sleep mode, the outputs and
all internal circuitry are OFF to minimize current draw. In
addition, all SPI-configurable features of the device are reset.
The 06XS3517 will transit to two modes (Normal and Fail)
depending on wake and fail signals (see Fig13).
The transition to the other modes is according following
signals:
• Wake = IGN or IGN_ON or FLASHER or
FLASHER_ON or RSTB or FOG or FOG_ON
• Fail = VCC fail or SPI fail or External limp
NORMAL MODE
The 06XS3517 is in Normal mode when:
• Wake = 1
• Fail = 0
In Normal operating mode the power outputs are under full
control of the SPI as follows:
• The outputs 1 to 6, including multiphase timing and
selectable slew-rate, are controlled by the
programmable PWM module.
• The outputs 1 to 5 are switched OFF in case of an
undervoltage on VBAT.
• The outputs 1 to 5 are protected by the selectable
overcurrent double window and overtemperature
shutdown circuit.
• The digital diagnosis feature transfers status of the
smart outputs via the SPI.
• The analog current sense output (current recopy
feature) can be routed by the SPI.
• The outputs 1 and 5 can be configured to control LED
loads.
• The SPI reports NM = 1 in this mode.
The figure below describes the PWM, outputs and
overcurrent behavior in Normal mode.

FAIL MODE
The 06XS3517 is in Fail mode when:
• Wake = 1
• Fail = 1
In Fail mode:
• The outputs are under control of external pins (see
Table 7)
• The outputs are fully protected in case of an overload,
overtemperature and undervoltage (on VBAT or on
VCC).
• The SPI reports continuously the content of address 11
(Initialization register), regardless previously requested
output data word.
• Analog current sense is not available.
• Output 2 is configured in Xenon mode.
• In case of an overload (OCHI2 or OCLO) conditions or
undervoltage on VBAT, the outputs are under control of
autorestart feature.
• In case of serious overload condition (OCHI1 or OT) the
corresponding output is latched OFF until a new wakeup event (wake = 0 then 1).

AUTORESTART STRATEGY
The Autorestart is not limited in time.
The autorestart circuitry is used to supervise the outputs
and reactivate high-side switches in cases of overload or
undervoltage failure conditions, to provide a high availability
of the outputs.
Autorestart feature is available in Fail mode (after loss of
SPI communication). Autorestart is activated in case of
overload condition (OCHI2 or OCLO) or undervoltage
condition on VBAT (see Figure 12).
The autorestart periodically switches ON the outputs.
During ON state of the switch OCHI1 window is enabled for
tochi_Auto, then after the output is protected by OCLO.
Output current
OCHI1
OCLO or UV fault
Auto period
To leave Fail mode, the fail condition must be removed
(fail =0). The microcontroller has to toggle the SPI D10 bit (0
to 1) to reset the watchdog bit (WD); the other bits are not
considered. The previous latched faults are reset by the
transition into Normal mode.
TRANSITION NORMAL TO FAIL MODE
To leave the Normal mode, a fail condition must occur (fail
= 1). The previous latched faults are reset by the transition
into Fail mode.
If the SI is shorted to VDD, the device transmits to Fail
Safe mode until the WD bit toggles through the SPI (from [0]
to [1]).
All settings are according to predefined values (all bits set
to logic [0]).

Figure 9. Overcurrent window in case of Autorestart
In case of OCHI1 or OT, the channel is latched OFF until
wake-up (wake = 0 then 1).
In case of OCLO or undervoltage, the output is switched
OFF and turned On again automatically after the autorestart
period (150 ms for 6.0 mOhm channels or 75 ms for
17 mOhm channels).
In case of an undervoltage in Fail mode, the outputs 1 to 5
will be latched off. The corresponding output is switched on
only after the autorestart period (tAUTORST-T1 or tAUTORST-T2).
The 06XS3517 enters in Normal mode after start-up if
following sequence is provided:
• VBAT and VCC power supplies must be above their
undervoltage thresholds (Sleep mode).
• generate wake up event (wake = 1) from 0 to 1 on RSTB.
The device switches to Normal mode.
• apply PWM clock after maximum 200 μs (min 50 μs).
• send SPI command to the Device status register to clear
the clock fail flag to enable the PWM module to start.
Figure 10 describes the wake-up block diagram.
POWER OFF MODE
The 06XS3517 is in Power OFF mode when the battery
voltage is below VBATPOR[1,2] thresholds. For more details,
refer to Loss of VBAT.

LOGIC COMMANDS AND REGISTERS
LOGIC COMMANDS AND REGISTERS
SERIAL INPUT COMMUNICATION
SPI communication compliant to 3.3 V and 5.0 V is
accomplished using 16-bit messages. A message is
transmitted by the master starting with the MSB, D15, and
ending with the LSB, D0. Each incoming command message
on the SI pin can be interpreted using the bit assignment
described in Table 8. The 5 bits D15 : D11, called register
address bits, are used to select the command register. Bit
D10 is the watchdog bit. The remaining 10 bits, D9 : D0, are
used to configure and control the output and its protection
features. Multiple messages can be transmitted in
succession to accommodate those applications where daisy
chaining is desirable or to confirm transmitted data as long as
the messages are all multiples of 16 bits. Any attempt made
to latch in a message that is not 16 bits will be ignored.
All SPI registers are reset (all bit equal 0) in case of RSTB
equal 0 or fail mode (Fail=1).

ADDRESS 00000 — INITIALIZATION
The Initialization register is used to read the various
statuses, choose one of the six outputs current recopy, load
the H7 bulbs profile for OUT2 only, enable the FOG pin and
synchronize the switching phases between different devices.
The register bits D1 and D0 determine the content of the 16
bits of the next SO data. (Refer Serial Output Communication
(Device Status Return Data)) Table describes the register of
initialization.
The watchdog timeout is specified by t WDTO parameter. As
long as the WD bit (D10) of an incoming SPI message is
toggled within the minimum watchdog timeout period
(WDTO), the device will operate normally. If an internal
watchdog timeout occurs before the WD bit is toggled, the
device will revert to Fail mode. All registers are cleared. To
exit the Fail mode, send valid SPI communication with
WD bit = 1.

ADDRESS 00001 — CONFIGURATION OL
ADDRESS 00011 — CONFIGURATION CSNS
The Configuration OL register is used to enable the open
load detection for LEDs in Normal mode (OLLEDn in Table 9)
and to active the LED Control.
When bit D0 is set to logic [1], the open load detection
circuit for LED is activated for output 1. When bit D0 is set to
logic [0], open load detection circuit for standard bulbs is
activated for output 1.
When bit D5 is set to logic [1], the LED Control is activated
for output 1.
The Configuration Current Sense register is used to
disable the high overcurrent shutdown phase (OCHI1 and
OCHI2 dynamic levels) in order to activate immediately the
current sense analog feedback.
When bit D9 is set to logic [1], the current sense
synchronization signal is reported on FETOUT output pin.
When the corresponding NO_OCHI bit is set to logic [1],
the output is only protected with OCLO level. The current
sense is immediately available if it is selected through the
SPI, as described in Figures 13. The NO_OCHI bit per output
is automatically reset at each corresponding ON/OFF bit
transition from logic [1] to [0], and in case of overtemperature
or overcurrent fault. All NO_OCHI bits are also reset in case
of undervoltage fault detection.
ADDRESS 00010 — CONFIGURATION PRESCALER
AND SR
Two configuration registers are available at this address.
The Configuration Prescaler when D9 bit is set to logic [0] and
Configuration SR when D9 bit is set to logic [1].
The Configuration Prescaler register is used to enable the
PWM clock prescaler per output. When the corresponding
PR bit is set to logic [1], the clock prescaler (reference clock
divided by 2) is activated for the dedicated output.
The SR Prescaler register is used to increase the output
slew rate by a factor of 2. When the corresponding SR bit is
set to logic [1], the output switching time is divided by 2 for the
dedicated output.

new message data is clocked into the SI pin. The first 16 bits
of data clocking out of the SO, and following a CSB transition,
is dependant upon the previously written SPI word (SOA1
and SOA0 defined in the last SPI initialization word).
Any bits clocked out of the SO pin after the first 16 will be
representative of the initial message bits clocked into the SI
pin since the CSB pin first transitioned to a logic [0]. This
feature is useful for daisy chaining devices.
A valid message length is determined following a CSB
transition of logic [0] to logic [1]. If the message length is
valid, the data is latched into the appropriate registers. A valid
message length is a multiple of 16 bits. At this time, the SO
pin is tri-stated and the fault status register is now able to
accept new fault status information.
The output status register correctly reflects the status of
the Initialization-selected register data at the time that the
CSB is pulled to a logic [0] during SPI communication and / or
for the period of time since the last valid SPI communication,
with the following exceptions:
• The previous SPI communication was determined to be
invalid. In this case, the status will be reported as though
the invalid SPI communication never occurred.
• Battery transients below 6.0 V, resulting in an
undervoltage shutdown of the outputs, may result in
incorrect data loaded into the status register.

The register bits are reset by a read operation and also if
the fault is removed.

PROTECTION AND DIAGNOSIS FEATURES
OUTPUT PROTECTION FEATURES
The 06XS3517 provides the following protection features:
• Protection against transients on VBAT supply line (per
ISO 7637)
• Active clamp, including protection against negative
transients on output line
• Overtemperature
• Severe and resistive overcurrent
• Open Load during ON state
These protections are provided for each output (OUT1:5).

Overtemperature Detection
The 06XS3517 provides overtemperature shutdown for
each output (OUT1:OUT5 ). It can occur when the output pin
is in the ON or OFF state. An overtemperature fault condition
results in turning OFF the corresponding output. The fault is
latched and reported via the SPI. To delatch the fault and be
able to turn ON again the outputs, the failure condition must
be removed (T< 175 °C, typically) and:
• if the device was in Normal mode, the output
corresponding register (bit D7) must be rewritten.
Application of complete OCHI window (OCHI1+OCHI2
during t2) depends on toggling or not toggling the D7 bit.
• if the device was in Fail mode, the corresponding output is
locked until restart of the device: wake-up from Sleep
mode or VBATPOR1.
The corresponding SPI fault report (OTS bit) is removed
after a read operation.
Overcurrent Detections
The 06XS3517 provides a dynamic overcurrent shutdown
protection (see Figure 12) in order to protect the internal
power transistors and the harness in the event of overload
(fuse characteristic).

Figure 12. Two-segment Overcurrent Window in Normal
Mode
OCHI (IOCHI1 and then IOCHI2) is only activated after
toggling D7 bit of the corresponding Control Out registers in
Normal Mode. During switch-on, a severe short-circuit
condition at the output is reported as an OCHI fault. In Fail
Mode, the control of OCHI window is provided by the toggles:
IGN_ON, Flasher_ON, and FOG_ON. The current thresholds
(IOCHI1, IOCHI2 and IOCLO) and the time (t1 and t2) are fixed
numbers for each channel. After t2, the OCLO current
threshold is activated to protect in steady state. t1 and t2 times
are compared to “on” state duration (tON) of the output. In
case of the output is controlled in PWM mode during the
inrush period, the tON corresponds to the sum of each “ON”
state duration in order to only account for times the channel
was actually in the ON state.
OUT2 is default loaded with the Xenon profile. The use of
H7 bulbs at this output requires SPI programming (Xenon
bit).
In case of overload (OCHI1 or OCHI2 or OCLO detection),
the corresponding output is disabled immediately. The fault is

latched and the status is reported via the SPI. To delatch the
fault, the failure condition must be removed and:
For OCHI1:
• if the device was in Normal mode: the channel’s
associated on/off bit (bit D7) must be rewritten D7=1.
Application of complete OCHI window depends on
toggling or not toggling D7 bit.
• if the device was in Fail mode, the failure is locked until
restart of the device: wake-up from Sleep mode or
VBATPOR1.
For OCHI2 and OCLO:
• if the device was in Normal mode: channel’s associated
on/off bit (bit D7) must be rewritten D7=1. Application of
complete OCHI window depends on toggling or not
toggling D7 bit.
• if the device was in Fail mode, Autorestart is activated. The
device Autorestart feature opens a fixed window width and
restarts at a fixed period with OCHI1 window. Autorestart
feature resets OCHI2 or OCLO fault after corresponding
Autorestart period.
The SPI fault reports are removed together after a read
operation:
- OC bit=(OCHI1) or (OCHI2) fault
- OVL bit=(OCHI1) or (OCHI2) or (OCLO) fault
Overvoltage detection and active clamp
The 06XS3517 possesses an active gate clamp circuit in
order to limit the maximum drain to source voltage.
In case of overload on an output the corresponding switch
(OUT[1 to 5]) is turned off which leads to high-voltage at
VBAT with an inductive VBAT line. The maximum VBAT
voltage is limited at VBATCLAMP by automatically turning on
the channel. In case of open load condition, the positive
transient pulses (ISO 7637 pulse 2 and inductive battery line)
shall also be handled by the application.
Figures 13 and 14 describe the faults management in
Normal mode and Fail mode.

DIAGNOSTIC Functions
Open Load
The 06XS3517 provides open load detection for each
output (OUT1:OUT5 ) when the output pin is in the ON state.
Open load detection levels can be chosen by the SPI to
detect a standard bulb, a Xenon bulb for OUT2 only, or LEDs
(OLLED bit). Open load for LEDs only is detected during each
regular switch-off state or periodically each t OLLED (fully-on,
D[6:0] = 7F). To detect OLLED in fully on state, the output
must be on at least t OLLED. When an open load has been
detected, the output stays ON.
To delatch the fault bit, the condition should be removed
and the SPI read operation is needed (OL bit). In case of a
Power on Reset on VBAT, the fault will be reset.
Current Sense
The 06XS3517 diagnosis for load current (OUT1:6) is
done using the current sense (CSNS) pin connected to an
external resistor. The CSNS resistance value is defined in
function to VCC voltage value. It is recommended to use
resistor 500 Ohm < RCSNS < 5.0 kOhm. Typical value is
1.0 kOhm for 5.0 V application. The channel the current of
which is sensed is addressed through bits MUX[4,2] bits of
the Initialization register.
The current recopy feature for OUT1:5 is disabled during
a high overcurrent shutdown phase (t2) and is only enabled
during low overcurrent shutdown thresholds. The current
recopy output delivers current only during ON time of the
output switch without overshoot (aperiodic settling).
The current recopy is not active in Fail mode.
With a calibration strategy, the output current sensing
precision can be improved significantly. One calibration point
at 25 °C for 50% of FSR allows removing part to part
contribution. So, the calibrated part precision goes down to
±6.0% over [20% - 75%] output current FSR, overvoltage
range (10 V to 16 V) and temperature range (-40 to 125 °C).

Board Temperature Feedback
TEMPERATURE PREWARNING
The 06XS3517 provides a voltage proportional to the
temperature on the GND flag, often representative for the
temperature of the underlaying PCB land. This voltage is
available at the CSNS output pin when the associated
UX[2,0] bits are set to “111”. Figure 15 shows the output
voltage over temperature.
The 06XS3517 provides a temperature prewarning
reported via the SPI (OTW bit) in Normal mode. The
information is latched. To delatch, a read SPI command is
needed. In case of a Power on Reset, the fault will be reset.

The 06XS3517 provides the status of the FLASHER, FOG,
and IGN pins via the SPI in real time and in Normal mode.

REVERSE POLARITY PROTECTION ON VBAT
In case of a permanently reverse voltage operation, the
channels are turned ON (RSD Ohm) in order to prevent
thermal overloads. No protections are available.
An external diode on VCC is necessary in order to protect
the 06XS3517 in cases from reverse polarity.
In case of negative transients on the VBAT line (per
ISO 7637), the VCC supplied functions are still available
operating, while the VBAT line is negative. Without loads on
OUT1:5 pin, an external clamp between VBAT and GND is
mandatory to avoid exceeding maximum ratings. The
maximum external clamp voltage shall be between the
reverse battery condition and -20 V.
Therefore, the device is protected against latch-up with or
without load on OUT outputs.

Output Voltage Status
The 06XS3517 provides the state of OUT1:OUT5 outputs
in real time through the SPI. The OUT bit is set to logic [1]
when the corresponding output voltage is higher or equal
then half of the supply voltage. This bit allows synchronizing
current sense and diagnosing short-circuit between OUT and
VBAT terminals.
During an undervoltage of VBAT
(VBATPOR1 < VBAT < VBATUV), the outputs [1 - 5] are switched
off immediately. No current path from VBAT to VCC exists.
The external MOSFET (OUT6) can be controlled in Normal
mode by the SPI if VCC is above VCCUV. The fault is reported
to the UVF bit (OD13). To delatch the fault, the undervoltage
condition should be removed and:
• To turn-on the output, the corresponding D7 bit must be
rewritten to logic [1] in Normal mode. Application of the
OCHI window depends on toggling or not toggling the
D7 bit.
• If the device was in Fail mode, the fault will be delatched
by the Autorestart feature periodically.

FUNCTIONAL DEVICE OPERATION
PROTECTION AND DIAGNOSIS FEATURES
In case of VBAT < VBATPOR1 (Power OFF mode), the
behavior depends on VCC:
• all latched faults are reset if VCC < VCCUV,
• all latched faults are maintained under VCC in nominal
conditions. In case VBAT is disconnected, OUT[1:5]
outputs are OFF. OUT6 output state depends on the
previous SPI configuration. The SPI configuration,
reporting, and daisy-chain features are provided for
RST is set to logic [1]. The SPI pull-up and pull-down
current resistors are available. This fault condition can
be diagnosed with UVF fault in OD13 reporting bit. The
previous device configuration is maintained. No current
is conducted from VCC to VBAT.
LOSS OF VCC (DIGITAL LOGIC SUPPLY LINE)
LOSS OF GROUND (GND)
During loss of ground, the 06XS3517 cannot drive the
loads (the outputs (1:5) are switched OFF), but is not
destroyed by the operating condition. Current limit resistors in
the digital input lines protect the digital supply against
excessive current (1.0 kOhm typical). The state of the
external smart power switch controlled by FETOUT is not
guaranteed, and the state of external smart MOS is defined
with an external termination resistor.
FATAL MISTREATMENT OF LOGIC I / O PINS
The digital I / Os are protected against fatal mistreatment
by signal plausibility check according to Table 17.
Table 17. Logic I / O Plausibility Check
During loss of VCC (VCC < VCCUV ) and with wake = 1, the
06XS3517 is switched automatically into Fail mode. The
external smart MOSFET is turned OFF. All SPI registers are
reset and must be reprogrammed when VCC goes above
VCCUV. The device will transit in OFF mode if VBAT <
VBATPOR2.
LOSS OF VCC AND VBAT
If the external VBAT and VCC supplies are disconnected (or
not within specification: (VCC and VBAT) < VBATPOR1), all SPI
register contents are reset with default values corresponding
to all SPI bits are set to logic [0] and all latched faults are also
reset.
