Abstract
A Hall sensor component includes an assembly unit with a Hall sensor and a processing device. The Hall sensor has an electric current input for providing a Hall sensor output signal depending on a magnetic field acting on the Hall sensor and depending on the electric current. The processing device is arranged for receiving an input signal including the Hall sensor output signal and processing the input signal to provide an output signal associated with the Hall sensor output signal. A signal generator generates a diagnosis signal. The signal generator sends the diagnosis signal to the assembly unit as one of a control signal of the electric current input, to form a Hall sensor mixed output signal dependant on said diagnosis signal, and as a mixing signal to mix with said Hall sensor output signal to form a Hall sensor mixed output signal dependant on said diagnosis signal. The Hall sensor mixed output signal is provided as the processing device input signal.
