Rev. 6.0, 6/2012
Smart Front Corner Light Switch
(Triple 10 mOhm and Dual
35 mOhm)
10XS3535
The 10XS3535 is designed for low voltage automotive and industrial
lighting applications. Its five low RDS(ON) MOSFETs (three 10 mΩ, two
35 mΩ) can control the high sides of five separate resistive loads
(bulbs, Xenon-HID modules and LEDs).
Programming, control and diagnostics are accomplished using a
16-bit SPI interface (3.3 V or 5.0 V). Each output has its own pulsewidth modulation (PWM) control via the SPI. The 10XS3535 has highly
sophisticated failure mode handling to provide high availability of the
outputs. Its multiphase control and output edge shaping improves
electromagnetic compatibility (EMC) behavior.
The 10XS3535 is packaged in a power-enhanced 12 x 12 mm
nonleaded PQFN package with exposed tabs.

SPI Logic power supply.
SPI data is sent to the MCU by this pin. This data output changes on the
negative edge of SCLK and when CS is high, this pin is high-impedance.
This pin controls an external SMART MOSFET by logic level. This output is also
called OUT6.
If OUT6 is not used in the application, this output pin is set to logic high when
the current sense output becomes valid when CSNS sync SPI bit is set to logic

41. Not production tested.
42. The PWM ratio is measured at VOUT = 50% of VBAT in nominal range of PWM frequency. It is possible to put the device fully on (PWM
duty cycle = 100%) and fully off (PWM duty cycle = 0%). Between 4%-96%, OCHI1,2, OCLO and open load are available in ON state.
See Figure 6, Output Slew Rate and Time Delays.
43. Linear range is defined by output duty cycle to SPI duty cycle configuration +/-1 LSB. For values outside linear duty cycle range, a
calibration curve is available.
44. Full diagnostic corresponds to the availability of the following features: output current sensing, output status and open load detection. Not
production tested.

FUNCTIONAL DESCRIPTION
INTRODUCTION
FUNCTIONAL DESCRIPTION
INTRODUCTION
The 10XS3535 is designed for low-voltage automotive and
industrial lighting applications. Its five low RDS(ON) MOSFETs
(three 10 mΩ and two 35 mΩ) 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 10XS3535 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.

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 duty cycle (bits D[6:0]).
The following table describes the PWM resolution.

The timing includes four programmable PWM switching
phases (0°, 90°, 180°, and 270°) to improve overall EMC
behavior of the light module.
The amplitude of the input current is divided by four while
the frequency is 4 times the original one. The two following
pictures illustrate this behavior.

The synchronization of the switching phases between
different IC is provided by an SPI command in combination
with the CS 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:
•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.
If RST=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.

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 is used to control an external MOSFET
(OUT6).
FLASHER INPUT (FLASHER)
The high level of the FETOUT Output is VCC, if VBAT and
VCC are available, in case FETOUT is a controlled ON.
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.
FETOUT is not protected if there is a short-circuit or undervoltage on VBAT.
In case of a reverse battery, OUT6 is OFF.
FOG INPUT (FOG)
FET IN INPUT (FETIN)
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.
This input pin gives the current recopy of the external
MOSFET. It can be routed on CSNS output by a SPI
command.
RESET INPUT (RST)
SPI PROTOCOL DESCRIPTION
This input wakes the device when the RST 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 7 and Table 10 are reset. The fault
management is not affected by RST.
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 (CS).
The SI/SO pins of the 10XS3535 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:
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. So, the current sense
monitoring can be synchronized with a rising edge on the
FETOUT pin (tCSNS(SYNC)) if CSNS sync SPI bit is set to logic
[1]. 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 timeslot, upon a switch-off command, this feature may be used to
implement maximum current control.
CHARGE PUMP (CP)
An external capacitor is connected between this pin and
the VBAT pin. It is used as a tank for the internal charge
pump. Its value is 100 nF ± 20%, 25 V maximum.
SERIAL CLOCK (SCLK)
The SCLK pin clocks the internal shift registers of the
10XS3535 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 CS makes any transition.
For this reason, it is recommended the SCLK pin be in a logic
[0] whenever the device is not accessed (CS logic [1] state).
SCLK has a passive pull-down, RDWN. When CS is logic [1],
signals at the SCLK and SI pins are ignored and SO is tristated (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 CS 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 10XS3535 device
latches in data from the Input Shift registers to the addressed
registers on the rising edge of CS. The device transfers
status information from the power output to the Shift register
on the falling edge of CS. The SO output driver is enabled
when CS is logic [0]. CS should transition from a logic [1] to a
logic [0] state only when SCLK is a logic [0]. CS 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 CS 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.

OPERATIONAL MODES
SLEEP MODE
The Sleep mode is the default mode of the 10XS3535.
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 RST 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 10XS3535 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 RST or FOG or FOG_ON
• Fail = VCC fail or SPI fail or External limp
NORMAL MODE
The 10XS3535 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
under-voltage on VBAT.
• The outputs 1 to 5 are protected by the selectable overcurrent double window and over-temperature shutdown
circuit.
• The digital diagnosis feature transfers status of the
smart outputs via SPI.
• The analog current sense output (current recopy
feature) can be routed by SPI.
• The outputs 1 and 5 can be configured to control LED
loads: RDS(ON) is increased by a factor of 2 and the
current recopy ratio is scaled by a factor of 4.
• The SPI reports NM=1 in this mode.
The figure below describes the PWM, outputs and overcurrent behavior in Normal mode.

FAIL MODE
The 10XS3535 is in Fail mode when:
• Wake = 1
• Fail = 1
In Fail mode:
• The outputs are under control of external pins (see
Table 5)
• The outputs are fully protected in case of an overload,
over-temperature and under-voltage (on VBAT or on
VCC).
• The SPI reports continuously the content of address 11,
disregard to previous 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
under-voltage 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 circuitry is used to supervise the outputs
and reactivate high side switches in cases of overload or
under-voltage failure conditions, to provide a high availability
of the outputs.
Autorestart feature is available in Fail mode when no
supervising intelligence of the microcontroller is available.
Autorestart is activated in case of overload condition (OCHI2
or OCLO) or under-voltage condition on VBAT (see
Figure 12).
The autorestart 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
In case of under-voltage in Fail mode, the outputs 1 to 5
will be latched off. The corresponding output is switched on
only after its autorestart period (tAUTORST-T1 or tAUTORST-T2).
The Autorestart is not limited in time.
TRANSITION FAIL TO NORMAL MODE
To leave the 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; 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 VCC, 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]).

SERIAL INPUT COMMUNICATION
Table 6. SI Message Bit Assignment
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 6. 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.

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 to the section entitled Serial
Output Communication (Device Status Return Data)
beginning on page 30.) Table 8 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 7,
page 28) and to active the LED Control.
The Configuration Current Sense register is used to
disable the high over-current shutdown phase (OCHI1 and
OCHI2 dynamic levels) in order to activate immediately the
current sense analog feedback.
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.
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.
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. And the current
sense is immediately available if it is selected through SPI, as
described in Figures 13. The NO_OCHI bit per output is
automatically reset at each corresponding ONoff bit transition
from logic [1] to [0] and in case of over-temperature or overcurrent fault. All NO_OCHI bits are also reset in case of
under-voltage fault detection.

Bit D7 at logic [1] turns ON OUT1. OUT1 is turned OFF
with bit D7 at logic [0]. This register allows the master to
control the duty cycle and the switching phases of OUT1. The
duty cycle resolution is given by bits D6 : D0.
D7 = 0, D6 : D0 = XX output OFF.
D7 = 1, D6 : D0 = 00 output ON during 1/128.
D7 = 1, D6 : D0 = 1A output ON during 27/128 on PWM

SERIAL OUTPUT COMMUNICATION (DEVICE
STATUS RETURN
DATA)
When the CS pin is pulled low, the output register is
loaded. Meanwhile, the data is clocked out MSB first as the
new message data is clocked into the SI pin. The first 16 bits
of data clocking out of the SO, and following a CS 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 CS pin first transitioned to a logic [0]. This
feature is useful for daisy chaining devices.
A valid message length is determined following a CS
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 CS
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 SPI register, except the UVF fault
reporting (OD13).
SERIAL OUTPUT BIT ASSIGNMENT
The contents of bits OD15 : OD0 depend on bits D1: D0
from the most recent initialization command SOA[1:0] (refer
to Table 7, page 28), as explained in the paragraphs that
follow.
The register bits are reset by a read operation and also if
the fault is removed.

PROTECTION AND DIAGNOSIS FEATURES
OUTPUT PROTECTION FEATURES
The 10XS3535 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
•Over-temperature
•Severe and resistive Over-current
•Open Load during ON state
These protections are provided for each output (OUT1:5).
Over-temperature detection
The 10XS3535 provides over-temperature shutdown for
each output (OUT1:OUT5 ). It can occur when the output pin
is in the ON or OFF state. An over-temperature fault condition
results in turning OFF the corresponding output. The fault is
latched and reported via 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.
OCHI (IOCHI1 and then IOCHI2) is only activated after
toggling D7 bit in Normal Mode. During the switch-on, a
severe short-circuit condition provided on the module
connector 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 driver. After t2, OCLO current threshold is set 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
expand dynamically the transient overcurrent profile.
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 SPI. To delatch the
fault, the failure condition must be removed and:
For OCHI1:
•if the device was in Normal Mode: the output
corresponding register (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:
Over-current detections
The 10XS3535 provides intelligent over-current shutdown
(see Figure 12) in order to protect the internal power
transistors and the harness in the event of overload (fuse
characteristic).

DIAGNOSTIC
Open Load
The 10XS3535 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 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 diagnosis, 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 10XS3535 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 Ω < RCSNS < 5.0 kΩ. Typical value is 1.0 kΩ for
5.0 V application. The routing of the current sense sources is
SPI programmable (MUX[2,0] bits).

With a calibration strategy, the output current sensing

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, over voltage

This bit allows synchronizing current sense and diagnosing
short-circuit between OUT and VBAT terminals.
TEMPERATURE PREWARNING
The 10XS3535 provides a temperature prewarning
reported via the SPI (OTW bit) in Normal mode. The

needed. In case of a Power on Reset, the fault will be reset.

EXTERNAL PIN STATUS
The 10XS3535 provides the status of the FLASHER, FOG,

FAILURE HANDLING STRATEGY
A highly sophisticated failure handling strategy enables
light functionality even in case of failures inside the
component or the light module. Components are protected
against:
• Reverse Polarity
• Loss of Supply Lines
• Fatal Mistreatment of Logic I/O Pins
REVERSE POLARITY PROTECTION ON VBAT
In case of a permanently reverse polarity operation, the
output transistors are turned ON (Rsd) to prevent thermal
overloads and no protections are available.
An external diode on VCC is necessary in order to not to
destroy the 10XS3535 in cases of reverse polarity.
In case of negative transients on the VBAT line (per
ISO 7637), the VCC line is still operating, while the VBAT line
is negative. Without loads on OUT1:5 terminal, an external
clamp between VBAT and GND is mandatory to avoid
exceeding maximum rating. 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.
LOSS OF SUPPLY LINES
The 10XS3535 is protected against the loss of any supply
line. The detection of the supply line failure is provided inside
the device itself.
LOSS OF VBAT
During an under-voltage of VBAT (VBATPOR1 <
VBAT < VBATUV), the outputs [1-5] are switched off
immediately. No current path from VBAT to VCC. The
external MOSFET (OUT6) can be controlled in Normal Mode
by the SPI if VCC remains and is above VCCUV. The fault is
reported to the UVF bit (OD13). To delatch the fault, the
under-voltage 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.
In case of VBAT < VBATPOR1 (Power OFF mode), the
behavior depends on VCC:
• 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)
During loss of VCC (VCC < VCCUV ) and with wake=1, the
10XS3535 is switched automatically into Fail mode (no
deglich time). The external SMART MOSFET is 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.
LOSS OF GROUND (GND)
During loss of ground, the 10XS3535 cannot operate 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 (1kohm 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 15.
