Abstract
A Hall effect sensor system includes a Hall effect sensor and a drive-sense circuit (DSC). The Hall effect sensor includes an input port to receive a DC (direct current) current signal and generates a Hall voltage based on exposure to a magnetic field. The DSC generates the DC current signal based on a reference signal and drives it via a single line that operably couples the DSC to the Hall effect sensor and simultaneously to sense the DC current signal via the single line. The DSC detects an effect on the DC current signal corresponding to the Hall voltage that is generated across the Hall effect sensor based on exposure of the Hall effect sensor to the magnetic field and generates a digital signal representative of the Hall voltage.
