Abstract
A method includes receiving a first signal at an input of a device driver included at an electronic device, the first signal representing first information. A second signal representing the first information is provided at an output of the device driver. The output of the device driver, under normal operating conditions, is coupled to an output terminal of the electronic device. A third signal at the output terminal is received at feedback circuitry of the electronic device. The feedback circuitry identifies a fault at the output terminal based on the third signal and the first signal.
