Abstract: Method and apparatus for providing error compensation for a magnetic field sensing element in a three-phase motor. In embodiments, a driving angle is determined from zero-crossings of the magnet pole-pairs and error compensation levels for the pole-pairs is determined to reduce distortions in the motor current waveform.

Abstract: A motor driver includes at least two terminals suitable for being coupled to a motor controller and to receive a motor command signal and transmit a motor status signal when the motor driver is controlling a motor. A serial data communication circuit may be configured to send and receive serial data over the at least two terminals when the at least two terminals are idle.
