Abstract
A sensor integrated circuit includes a sensing circuit configured to generate the sensor output signal and a fault circuit to detect a fault and generate a fault signal indicative of the fault. A combined signal indicative of the fault signal when a fault is detected and indicative of a reference voltage associated with the sensor IC at other times is provided at a shared connection of the sensor IC. Embodiments include a current sensor IC and fault detectors configured to detect one or more faults.
