Claims (3)
- 전위차를 탐지하고 그 전위차가 미리 정해진 값을 초과할때 제1신호를 발생하는 모니터링 회로수단과, 제1신호가 제공되지 않을때 전력전이(轉移)중에 제1회로가 디스에이블되도록 제1회로를 디스에이블시키며 상기 모니터링회로 수단에 연결된 디스에이블링 회로수단을 포함하고, 저전압에서 상이한 특성들을 지니는 반도체들로 제조되며 전위차에 의해 구동되는 제1회로를 전력전이 중에 보호하는 보호회로.
- 제1항에 있어서, 상기 제1회로는 BiCMOS회로로 구성되는 보호회로.
- 제1항에 있어서, 입력신호가 제공될때 제1회로를 디스에이블시키도록 제2신호를 공급하며 입력신호가 공급되는 로드를 모니터하는 추가 모니터링 회로를 포함하는 보호회로.※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
