A self-calibrating Hall sensor IC with direction detection.

A monolithic wheel speed sensor integrated circuit based on Hall effect is presented. Speed and motion direction of magnetic encoder wheels or ferromagnetic target wheels are detected. Two specific amplitudes of the magnetic input signal are detected as well. A two-wire current output directly linke...
