NXP Semiconductors High Side Switch IC Part #MC10XS3412CHFKR2 | IC | DEX

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 55/28 W 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. 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 functionality of the outputs in case of MCU damage.

Features

• Four protected 10 mΩ and 12 mΩ high-side switches (at 25 °C)
• Operating voltage range of 6.0 to 20 V with sleep current < 5.0 μA, extended mode from 4.0 to 28 V
• 8.0 MHz 16-bit 3.3 V and 5.0 V SPI control and status reporting with daisy chain capability
• PWM module using external clock or calibratable internal oscillator with programmable outputs delay management • Smart overcurrent shutdown, severe short-circuit, overtemperature protection with time limited autoretry, and Fail-safe mode in case of MCU damage
• Output OFF or ON openload detection compliant to bulbs or LEDs and short to battery detection
• Analog current feedback with selectable ratio and board temperature feedback
