35XS3500

Freescale Semiconductor Advance Information Document Number: MC35XS3500 Rev. 4.0, 5/2011 Smart Rear Corner Light Switch (Penta 35 mΩ) 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 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 nonleaded Power QFN package with exposed tabs.
