POWER SUPPLY
The 10XS3412 is designed to operate from 4.0 V to 28 V
on the VPWR pin. Characteristics are provided from 6.0 V to
20 V for the device. The VPWR pin supplies power to internal
regulator, analog, and logic circuit blocks. The V DD supply is
used for Serial Peripheral Interface (SPI) communication in
order to configure and diagnose the device. This IC
architecture provides a low quiescent current Sleep mode.
Applying V PWR and V DD to the device will place the device in
the Normal mode. The device will transit to Fail-safe mode in
case of failures on the SPI or/and on V DD voltage.
HIGH SIDE SWITCHES: HS0 – HS3
These pins are the high side outputs controlling
automotive lamps located for the front of vehicle, such as
65 W/55 W bulbs and Xenon-HID modules. Those N-channel
MOSFETs with 10 m ? & 12 m ? R DS(ON) are self-protected
and present extended diagnostics in order to detect bulb
outage and short-circuit fault condition. The HS output is
actively clamped during turn off of inductive loads and
inductive battery line. When driving DC motor or Solenoid
loads demanding multiple switching, an external recirculation
device must be used to maintain the device in its Safe
Operating Area.
MCU INTERFACE AND OUTPUT CONTROL
In Normal mode, each bulb is controlled directly from the
MCU through SPI. A pulse width modulation control module
allows improvement of lamp lifetime with bulb power
regulation (PWM frequency range from 100 to 400 Hz) and
addressing the dimming application (day running light). An
analog feedback output provides a current proportional to the
load current or the temperature of the board. The SPI is used
to configure and to read the diagnostic status (faults) of high
side outputs. The reported fault conditions are: open load,
short circuit to battery, short circuit to ground (overcurrent
and severe short-circuit), thermal shutdown, and under/
overvoltage. Thanks to accurate and configurable
overcurrent detection circuitry and wire-harness optimization,
the vehicle is lighter.
In Fail-safe mode, each lamp is controlled with dedicated
parallel input pins. The device is configured in default mode.
