Abstract
In one aspect, an integrated circuit (IC) includes a magnetic field sensor to detect speed and direction of angular rotation of a rotating magnetic structure. The magnetic field sensor includes at least two magnetic field sensing elements configured to sense changes in a magnetic field caused by rotation of the magnetic structure. The IC also includes an output port configured to provide an output signal of the magnetic field sensor. The output signal indicates the speed and one of the direction or a fault.
