Abstract

A circuit may include an electronic switch that has a load current path coupled between an output node and a supply node and that is configured to connect or disconnect the output node and the supply node in accordance with a drive signal. Further, the circuit includes a monitoring circuit that is configured to receive a current sense signal, which represents the load current passing through the load current path, and that is further configured to determine a protection signal based on the current sense signal, a state of the monitoring circuit, and at least one wire parameter. The wire parameter characterizes a wire that is—during operation—connected to the output node, and the protection signal is indicative of whether to disconnect the output node from supply node. Further, the circuit includes a protection circuit connected to the monitoring circuit.
