Disclosed is a motor status detection circuit. The motor status detection circuit of the present invention comprises: a motor driving unit in which a motor relay switch is turned on or off according to a PWM signal outputted from a motor pre-driver; a counter electromotive force output control unit including a switch unit turned on by the motor relay switch, which outputs a counter electromotive force generated by the motor driving unit, when the switch unit is turned on; and a state determining unit which senses whether a motor is opened using the counter electromotive force outputted through the counter electromotive force output control unit. |
