For diagnosis purpose, the BTS4160DGA provides a status pin per channel.
7.1
BTS4160DGA status pins are an open drain, active low circuit.
as no “hard” failure mode occurs (Short circuit to GND / Over temperature or open load in OFF), the signal is
permanently high, and due to a required external pull-up to the logic voltage will exhibit a logic high in the
application. A suggested value for the
