Abstract: A voltage sensing circuit uses a voltage divider for providing a sense signal indicating the voltage across a circuit component. A current injector is used for injecting current to the sensing terminal. A sense signal is obtained with no current injection, to determine if a fault is present. The sensing terminal is coupled to the external circuit component via a voltage clamping component. A further sense signal is obtained in response to the injection of current. By comparing the sense signal in response to the injected current and a clamping voltage of the voltage clamping component, it can then be determined if the fault is caused by the circuit component or by the voltage divider.
