Quad High Side Switch (Dual 10m Ω, Dual 12mΩ) The 10XS3412 is one in a family of devices designed for low-voltage automotive lighting applications. Its four low RDS(ON) MOSFETs (dual 10m Ω/dual 12mΩ) can control four separate 55W / 28W bulbs, and/or Xenon modules, and/or LEDs. 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 10m Ω and 12mΩ high side switches (at 25°C) • Operating voltage range of 6.0V to 20V with sleep current < 5.0 μA, extended mode from 4.0V to 28V • 8MHz 16-bit 3.3V and 5V SPI control and status reporting with daisy chain capability • 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.
