Analog, Mixed Signal and Power Management MC07XS3200 Dual High Side Switch (7.0 mOhm) Overview The MC07XS3200 is one in a family of devices designed for low-voltage automotive lighting applications. Its two low RDS(ON) MOSFETs (dual 7.0 mΩ) can control four separate 55 W / 8 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 if desired. The MC07XS3200 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 damage. The MC07XS3200 is packaged in a Pb-free power-enhanced 32 pins SOIC package with exposed pad.
