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.
Features
• Four protected 10 mΩ and 35 mΩ high side switches (at 25 °C)
• Operating voltage range of 6.0 to 20 V with sleep current <
5.0 μA, 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
