Operation Mode
1) Output and fault reporting remains latched until falling DEN edge acknowledge.
2) Before fault acknowledgement and latch reset.
3) After fault acknowledgement and latch reset.
7.2
During normal operation, an enabled IS pin provides a sense current, which is proportional to the load current as
long as V
on sense current is provided after a sense settling time
is provided.
The output sense current is limited to I
