Quad high-side switch
(dual 10 mOhm, dual 35 mOhm)
10XS3435
The 10XS3435 is one in a family of devices designed for low voltage automotive
lighting applications. Its four low RDS(on) MOSFETs (dual 10 mOhm/dual
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.
Features
• Four protected 10 mOhm and 35 mOhm high-side switches (at 25 °C)

extended mode from 4.0 to 28 V
• 8.0 MHz 16-bit 3.3 V and 5.0 V SPI control and status reporting with daisy
chain capability
