NXP Semiconductors Document Number: MC10XS3435 Rev. 12.0, 8/2018 Technical Data Quad high-side switch 10XS3435 (dual 10 mOhm, dual 35 mOhm) The 10XS3435 is one in a family of devices designed for low voltage automotive lighting applications. Its four low R MOSFETs (dual 10 mOhm/dual DS(on) 35 mOhm) can control four separate 55/28 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. The 10XS3435 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. This device is powered using SMARTMOS technology.
