Claims (1)

스태핑 모타를 구동시킴에 있어 소정 입력되는 전류 차단신호에 의해 상기 스태핑 모터에 전력을 일시적으로 차단하는 기능을 가진 정전류 쵸퍼드라이버 IC를 구비하여 스태핑 모타 구동 신호(A,A,B,B)가 입력될때 스태핑 모타에 정전류 쵸퍼방식으로 전류를 공급하는 모타구동부(10)를 포함한 스태핑모타 구동회로에 있어서, 상기 모타구동부(10)에서 상기 전류차단 신호에 의해 상기 스태핑 모타(20)에 전류가 차단될때, 소정 신호에 의해 상기 스태핑모타(20)의 여자코일에 소정 정지 전류를 공급하여 상기 스태핑모타가 정지 상태를 소정의 토크로 유지할 수 있도록 하는 정지전류 공급부(30)를 포함함을 특징으로 하는 회로.In driving the stepping motor, a stepping motor driving signal (A, A, B, B) is inputted with a constant current chopper driver IC having a function of temporarily shutting off the power to the stepping motor by a current cutoff signal that is predetermined. In the stepping motor driving circuit including a motor driving unit 10 for supplying a current to the stepping motor in a constant current chopper method, when the current is blocked in the stepping motor 20 by the current blocking signal in the motor driving unit 10 And a stop current supply unit (30) for supplying a predetermined stop current to the excitation coil of the stepping motor (20) by a predetermined signal so that the stepping motor can maintain the stop state at a predetermined torque. . ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
