Advance Information

Quad High Side Switch

(Quad 35 mOhm)

35XS3400

The 35XS3400 is one in a family of devices designed for low-voltage

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

35 mOhm) can control four separate 28 W bulbs, 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 35XS3400 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 35 mΩ high side switches (at 25 °C)

• Operating voltage range of 6.0 V to 20 V with standby current <

5.0 μA, extended mode from 4.0 V to 28 V

FK SUFFIX (PB-FREE)

98ARL10596D

24-PIN PQFN

• 8.0 MHz 16-bit 3.3 V and 5.0 V SPI control and status reporting

with daisy chain capability

ORDERING INFORMATION

• PWM module using external clock or calibratable internal

oscillator with programmable outputs delay management

• Smart over-current shutdown, severe short-circuit, over-

temperature protection with time limited autoretry, and Fail-safe

mode in case of MCU damage
