ABSTRACT:
A motor driving circuit includes a control device, a detection module and a driving module. The control device is controlled by a control signal and is coupled to a motor. The control device includes a first terminal, a second terminal and a control terminal, wherein a driving current flowing through the motor flows through the first terminal and the second terminal. The detection module is used for detecting a voltage of the first terminal. The driving module is used for generating the control signal to control the driving current, wherein the detection module adjusts the driving capability of the driving module, thereby adjusting a slew rate of the control signal.
