ABSTRACT:
A two-lead Hall effect sensor (10) has a combined voltage supply and output terminal (12) and a ground or reference terminal (14). A Hall device (16), a comparator (18) and a voltage/current converter (20) are each connected between terminals (12) and (14). Hall device (16) supplies a first signal to comparator (18) when it senses a magnetic field strength above a predetermined amount, and supplies a second signal in the absence of the magnetic field strength. Comparator (18) in turn supplies either a first voltage state or a second voltage state to the converter (20). Converter (20) converts the first voltage state into a first current appearing at terminal (12), indicating the sensing of a magnetic field, and similarly converts the second voltage state to a second current, indicating a weak or absent magnetic field.
