MOTOR DRIVING APPARATUS

PROBLEM TO BE SOLVED: To provide a motor driving apparatus.SOLUTION: There is provided a motor driving apparatus capable of stably performing operation conversion between a normal mode and a sleep mode by counting a duty of a PWM signal according to a preset clock signal. The motor driving apparatus includes: a pulse width modulation (PWM) signal generating unit providing a PWM signal for driving a motor; a driving unit operating normally in the normal mode and waiting for operation in the sleep mode according to a control, and driving the motor in response to the PWM signal of the PWM signal generating unit; and a driving controlling unit counting the duty of the PWM signal according to the preset clock signal to determine an operation mode of the driving unit.
