Abstract
A circuit may comprise an electronic switch with a load current path, which is switched between an output node and a supply node and is designed to connect or disconnect the output node to or from the supply node in accordance with a control signal. The circuit further comprises a control circuit which is designed to generate the control signal based on an input signal, and a current monitoring circuit which is designed to receive a current measurement signal that represents the load current flowing through the load current path, and to generate a protective signal, based on the current measurement signal, which indicates whether the output node should be disconnected from the supply node. The circuit further comprises a reverse current detection circuit, which is designed to detect that the load current is flowing in the reverse direction, namely from the output node to the supply node.
