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 55/28 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.
