Abstract

A motor driver having a temperature sensing mechanism is provided. A control circuit determines a time for outputting a controlling signal according to a pulse-width modulation signal received from an external pulse-width modulation circuit. A driving circuit outputs a driving signal according to the controlling signal. An output stage circuit operates according to the driving signal to output an output stage signal to a motor to drive the motor to rotate. In a temperature sensing mode, a thermal sensor circuit senses a temperature inside the motor driver to output a temperature sensing signal. An external system circuit determines whether or not the motor driver causes overheating to the motor when being adapted to the motor according to the temperature sensing signal, and evaluates whether or not the motor driver is applicable to the motor.
