Smart Rear Corner Light Switch (Penta 35 mOhm)

The 35XS3500 is designed for low-voltage automotive and industrial lighting applications. Its five low RDS(ON) MOSFETs (five 35 mΩ) can control the high sides of five separate resistive loads (bulbs and LEDs).

Programming, control and diagnostics are accomplished using a 16-bit SPI interface (3.3 V or 5.0 V). Each output has its own pulsewidth modulation (PWM) control via the SPI. The 35XS3500 has highly sophisticated failure mode handling to provide high availability of the outputs. Its multiphase control and output edge shaping improves electromagnetic compatibility (EMC) behavior.

The 35XS3500 is packaged in a power-enhanced 12 x 12 mm nonleaded PQFN package with exposed tabs.
