Abstract
본 발명은 모니터의 릴레이 구동회로에 관한 것으로, 릴레이 구동 신호에 따라 온/오프되는 릴레이구동트랜지스터(Q1)가 턴 오프되는 순간에 다이오드(D1)을 통해 흐르는 역전류를 방지하기 위한 역전류방지 수단(20)이 추가로 구비되어, 릴레이의 채터링 현상을 방지하여 릴레이의 신뢰성을 향상시킬 수 있는 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a relay driving circuit of a monitor, wherein a reverse current preventing means for preventing reverse current flowing through a diode D1 at the moment when a relay driving transistor Q1 turned on / off in response to a relay driving signal is turned off. 20 is further provided to prevent chattering of the relay, thereby improving reliability of the relay.
