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.
High-side switches
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.
