Abstract

According to an embodiment, a diagnostic circuit is configured to be coupled to an output terminal of a switching circuit and to a sense terminal of a sense circuit coupled in parallel with the switching circuit. The diagnostic circuit includes a configurable feedback circuit configured to be coupled to the output terminal and the sense terminal. The configurable feedback circuit is configured to receive a select signal, switch a configuration of the configurable feedback circuit between a first mode and a second mode based on the select signal, sink a current from the sense circuit in the first mode, source a current to the sense circuit in the second mode, and balance a voltage difference between the output terminal and the sense terminal in the first mode and in the second mode.
