Abstract: A sensor device is provided with a magnetic field sensitive element being positioned in a magnetic field of a magnet. The magnetic field sensitive element is configured to sense an orientation angle of the magnetic field in the range between 0° and 360° and generate a sensing signal. The electronic circuitry is configured to receive and process the sensing signal from the magnetic field sensitive element to generate an angle signal indicating the orientation angle of the magnetic field and an angular speed of the shaft.

Abstract: A system includes a magnetic field sensor arrangement and a controller. The magnetic field sensor arrangement includes a first sensor chip having an integrated circuit differential magnetic field sensor circuit configured to generate a first output signal comprising first signal pulses, a second sensor chip having an integrated second differential magnetic field sensor circuit configured to generate a second output signal comprising second signal pulses, and at least one output signal terminal configured to output the first and the second output signals. The controller receives the first and the second signal pulses from the at least one output signal terminal, evaluates the first and the second signal pulses, and detects an error of an operation of the magnetic field sensor arrangement in response to the first and the second signal pulses not satisfying an expected output pattern of the first and the second signal pulses.
