Abstract
An integrated circuit is described herein. In accordance with one embodiment the circuit includes a transistor coupled between a supply pin and an output pin, a current output circuit configured to provide a diagnosis current at an current output pin, a current sensing circuit coupled to the transistor and configured to generate a first current sense signal indicative of a load current passing through the transistor and a second current sense signal indicative of the load current. The current output circuit is configured to select, dependent on a control signal, one of the following as diagnosis current: the first current sense signal and the second current sense signal.
