Protection Circuitry for Reversed Charger Connections to the DS2784 High-Side nFET Protector

The DS2784 high-side nFET protector has no protection circuitry for reversed charger connections. Therefore, it is possible for the DC FET to stay on during a fault condition if the charger is connected in reverse polarity. This article explains the external circuitry that can be used so that the DC FET turns off in the event of a reversed charger connection.
