FAB REQUALIFICATION

The 35XS3400 is one in a family of devices designed for low-voltage automotive lighting applications. Its four low RDS(ON) MOSFETs (quad 35 mOhm) can control four separate 28 W bulbs, 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 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.

This product is undergoing a fab migration and device qualification is not complete. PC samples are available now. For more information contact your local sales office.
