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.
