VC pin Under-Voltage

Reverse current is the only fault condition that

initiates gate turn-off of the MOSFET (as well as a

fault flag signal).

Forward Over-Current and

Forward Low-Current fault conditions issue a fault

that a fault condition may be present. This

information can be reported to a Host to signal that

some system level maintenance may be required.

ground through the internal shunt.
