<p>Disclosed herein is a motor driving circuit including: a duty ratio detection unit that detects a duty ratio of input pulse-width-modulation applied to control a speed of a motor; and a driving control unit that detects an output duty ratio corresponding to the duty ratio of the input pulse-width-modulation by using relationship data between the duty ratio of the input pulse-width-modulation and an output duty ratio that are previously stored and controls a duty ratio of a driving signal applied to the motor according to the output duty ratio. By this configuration, a speed of the motor can be accurately controlled.</p> |
