For diagnosis purpose, the BTS 6142D 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
During switch-on no current is provided, until the forward voltage drops below
typ. The output sense current is limited to
The pin IS provides in case of any fault conditions a defined fault current I
conditions are over-current (
The pin IS provides no current during open load in ON, de-energisation of inductive loads
and inverse current mode.
