Abstract
In accordance with one example, the electronic switch has a load current path operably coupled to a load via a wire; the electronic switch is configured to connect or disconnect a load current supply node and the load via the wire dependent on a drive signal. Further, the electronic fuse circuit includes a monitoring circuit configured to receive a current sense signal representing the load current passing through the wire and to determine a first protection signal based on the current sense signal and at least one wire parameter. The first protection signal is indicative of whether to disconnect the load current supply node from the load. Moreover, the electronic fuse circuit includes a logic circuit configured to receive at least one selection signal and to set the at least one wire parameter based on the at least one selection signal.
