The present invention relates to a high-side driver circuit. According to an embodiment of the present invention, the high-side driver circuit comprises: a high-side driver unit having one end connected to a load, and activated or deactivated for driving the load; a first circuit unit having one end connected to the other end of the high-side driver unit, and activating a passive lock function to deactivate the high-side driver unit; a second circuit unit having one end connected to the other end of the first circuit unit and generating a pull-down path to activate the passive lock function of the first circuit unit; and a control unit including a Zener diode, and controlling activation or deactivation of the second circuit unit.

    본 발명의 일 실시 예에 따른 하이 사이드 드라이버 회로는 일단이 부하와 연결되며, 상기 부하의 구동을 위해 활성화 또는 비활성화되는 하이 사이드 드라이버부, 일단이 상기 하이 사이드 드라이버부의 타단과 연결되며, 패시브 락(Passive Lock) 기능을 활성화하여 상기 하이 사이드 드라이버부를 비활성화하는 제1 회로부, 일단이 상기 제1 회로부의 타단과 연결되며, 폴-다운 경로(Pull-down Path)를 생성하여 상기 제1 회로부의 패시브 락 기능을 활성화하는 제2 회로부 및 제너 다이오드를 포함하며, 상기 제2 회로부의 활성화 또는 비활성화를 제어하는 제어부를 포함한다.
