Abstract
A motor driving device with stop mode setting and driving method thereof comprises a PWM converting circuit, an oscillator circuit, a first comparator, a second comparator, and a control unit. The second comparator compares a tunable stop setting signal with an analog signal to output a stop setting signal to the control unit. Therefore, the control unit determines a duty cycle for stopping a motor, and thus reducing energy loss of the motor and promoting motor efficiency.
