Abstract
A electrical circuit includes an excitation voltage connected via a first circuit path to an output, a switching device having a control terminal and first and second controlled terminals connected to the first circuit path, and a controller that generates a control signal provided to the control terminal of the switching device to selectively supply the excitation voltage to the output. Faults in the electrical circuit are detected by monitoring the switching device voltage at one of the controlled terminals of the switching device.
