Analog, Mixed Signal and Power Management MC10XS3412 Quad high side switch—dual 10 mOhm, dual 12 mOhm Applications Overview • Low-voltage automotive lighting Freescale Semiconductor’s third generation of its award-winning eXtreme Switch portfolio • Xenon bulbs features devices tailored for automotive lighting applications. These high side power switches • Halogen bulbs include the MC10XS3412, which is designed to drive high-intensity discharge (HID) light sources, • Light-emitting diodes (LEDs) improve efficiency, reduce wire harness size, and provide increased protection for longer bulb • High beam • Low beam life. Featuring four low RDS(ON) MOSFETs (dual 10 mΩ/dual 12 mΩ), the MC10XS3412 can control four separate 55 W/28 W bulbs, and/or Xenon modules, and/or LEDs. Programming, •Flashers control, and diagnostics are accomplished using a 16-bit SPI interface. Its output with selectable • Low-voltage industrial lighting 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 MC10XS3412 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 a damaged MCU.
