Abstract
A method of protecting a load circuit includes sensing a load current passing through a switch electrically in series with the load circuit, sensing a voltage drop across the switch, determining a rate of change of the voltage drop across the switch, determining whether to deactivate the switch based on the load current and the rate of change of the voltage drop across the switch, in response to determining to deactivate the switch, deactivating the switch to shut off current to the load circuit.
