... If this shutdown function is not needed, the pin can simply be connected to the V pin. Allowing this pin to IN float will cause erratic operation. Error Flag (FAN2501 only) To indicate conditions such as input voltage dropout (low V ), overheating, or overloading (excessive output cur- IN rent), the ERR pin indicates a fault condition open- ...
