Technical Data

Quad High Side Switch

(Quad 15 mOhm)

15XS3400

The 15XS3400 is one in a family of devices designed for low-voltage

automotive lighting applications. Its four low R_DS(ON)MOSFETs (quad

15 mOhm) can control four separate 55 W/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 15XS3400 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.
