For diagnosis purpose, the BTS4300SGA provides a status pin.
7.1
BTS4300SGA status pin is an open drain, active low circuit.
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 R
