Quad High Side Switch
(Dual 10 mOhm, Dual 12 mOhm)
10XS3412
The 10XS3412 is one in a family of devices designed for low-voltage
automotive lighting applications. Its four low RDS(ON) MOSFETs (dual
10 mOhm/dual 12 mOhm) can control four separate 55 W / 28 W
bulbs, and/or Xenon modules, and/or LEDs.
HIGH SIDE SWITCH
Programming, control and diagnostics are accomplished using a
16-bit SPI interface. Its output with selectable slew rate improves
electromagnetic compatibility (EMC) behavior. Additionally, each
output has its own parallel input or SPI control for pulse-width
modulation (PWM) control if desired. The 10XS3412 allows the user to
program via the SPI the fault current trip levels and duration of
acceptable lamp inrush. The device has fail-safe mode to provide fail-
safe functionality of the outputs in case of MCU damaged.
Features
• Four protected 10 mΩ and 12 mΩ high side switches (at 25°C)
• Operating voltage range of 6.0 V to 20 V with sleep current
< 5.0 μA, extended mode from 4.0 V to 28 V

98ARL10596D
24-PIN PQFN
• 8.0 MHz 16-bit 3.3 V and 5.0 V SPI control and status reporting
with daisy chain capability
ORDERING INFORMATION
Temperature
• PWM module using external clock or calibratable internal
oscillator with programmable outputs delay management
• Smart over-current shutdown, severe short-circuit, over-
temperature protections with time limited autoretry, and fail-safe
mode in case of MCU damage
• Output OFF or ON open-load detection compliant to bulbs or
LEDs and short to battery detection. Analog current feedback
with selectable ratio and board temperature feedback.
