The 12XS6 is the latest 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 feedback,
safety, and robustness.
HIGH-SIDE SWITCH
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.
