Document Number: MC35XS3500 Freescale Semiconductor Rev. 8.0, 8/2013 Technical Data Smart Rear Corner Light Switch 35XS3500 (Penta 35 mOhm) The 35XS3500 is designed for low-voltage automotive and industrial lighting applications. Its five low R MOSFETs (five DS(ON) 35 m ) can control the high sides of five separate resistive loads HIGH SIDE SWITCH (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 pulse- width 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.
