Smart Rear Corner Light Switch
(Penta 35 mOhm)
35XS3500
The 35XS3500 is designed for low-voltage automotive and
industrial lighting applications. Its five low RDS(ON) MOSFETs (five
35 m) can control the high sides of five separate resistive loads
(bulbs and LEDs).
HIGH SIDE SWITCH
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.

This input wakes the device. This pin has a passive internal pull-down.
When this signal is high, SPI signals are ignored. Asserting this pin low
starts a SPI transaction. The transaction is signaled as completed when
this signal returns high. This pin has a passive internal pull-up resistance.
This input pin is connected to the master microcontroller providing the
required bit shift clock for SPI communication. This pin has a passive
