For diagnosis purpose, the BTS50090-1TMB provides an IntelliSense signal at the pin IS.
The pin IS provides during normal operation a sense current, which is proportional to the load current as long as
V
the forward voltage drops below
The pin IS provides in case of any fault conditions a defined fault current
conditions are overcurrent (
The pin IS provides no current during open load in ON and de-energisation of inductive loads.
