The 12XS6 is the latest SMARTMOS achievement in automotive lighting drivers.

It belongs to an expanding family, which helps to control and diagnose

incandescent lamps and light-emitting diodes (LEDs), with enhanced precision.

It combines flexibility through daisy chainable SPI 5.0 MHz, extended digital and

analog feedbacks, safety, and robustness.

Output edge shaping helps to improve electromagnetic performance. To avoid

shutting off the device upon inrush current, while still being able to closely track

the load current, a dynamic overcurrent threshold profile is featured. Current of

each channel can be sensed with a programmable sensing ratio. Whenever

communication with the external microcontroller is lost, the device enters a fail

operation mode, but remains operational, controllable, and protected.

This new generation of high-side switch products family facilitates ECU design

due to compatible MCU software and PCB foot prints for each device variant.
