Quad High Side Switch
(Dual 10 mOhm, Dual 12 mOhm)
10XS3412
The 10XS3412 is one in a family of devices designed for low-voltage
automotive lighting applications. Its four low R_DS(ON) MOSFETs (dual
10 mOhm/dual 12 mOhm) can control four separate 55 W / 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 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.
