Technical Data
Smart Rear Corner Light Switch
(Penta 35 mOhm)
The 35XS3500 is designed for low-voltage automotive and
industrial lighting applications. Its five low R_DS(ON) MOSFETs (five
35 m) 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 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.
