Abstract
An integrated circuit has drive circuitry to drive the windings of an electrical motor, means to make a measurement from the drive circuitry during rotation of the motor, suitable for use as motor control feedback, and has an output contact through which the motor control feedback measurement is available as an analog output signal. It can be used with an external motor control circuit coupled to receive the analog output signal to generate motor control signals, to control the drive circuitry. The analog feedback output gives more flexibility to the design of a motor control loop in terms of bit resolution, bandwidth and choice of discrete time or continuous time control.
