MOTOR CONTROL CIRCUIT OVERCURRENT PROTECTION

摘要

A motor control circuit for controlling a motor, the circuit comprising a microcontroller operable to provide a driving current to the windings of the motor to be controlled and having an interrupt input which, once triggered, stops the driving current to the windings and thresholding circuitry operable to determine if a signal indicative of a winding current exceeds a reference level and, if so, to trigger the interrupt input.
