Description
Claims (3)
- 전원선(17)과 접지사이에 저항(1)과 다이오드(2) (3)을 차례로 직렬 접속하고, 상기 저항(1)과 다이오드(2)사이에는 서로의 출력측이 서로의 일입력측에 접속되고 래치기능을 갖는 NOR 게이트(4) (5)중 NOR 게이트(4)의 타입력측을 접속함과 함께 NOT 게이트(15) (16)로 이루어진 제1지연부의 입력측을 접속하고, 상기 NOR 게이트(4)의 출력측과 제1지연부의 출력측은 NOR 게이트(6)의 두 입력측에 이 NOR 게이트(6)의 출력측은 NOR 게이트(7)를 통해 전달게이트(8) (9)이 온, 오프 제어단자에 접속하고, 상기 전달게이트(8) (9)의 입력측은 공통으로 DC 전압측(Vcc)에 전달게이트(8)의 출력측은 NOT 게이트(11~14)로 이루어진 제2지연부를 통해 상기 NOR 게이트(5)의 타입력측에 전달게이트(9)의 출력측은 내부전자회로에 접속하고, 상기 제1지연부의 입력측과 전달게이트(8)의 출력측 사이에 풀다운용 저항(10)이 병렬 접속하여 구성함을 특징으로 하는 파워 리셋트 회로.
- 제1항에 있어서, 리셋트 신호의 전압 조정을 위해 상기 두개의 다이오드(2) (3)에 동일방향으로 또다른 다이오드를 추가로 직렬 접속한 것을 특징으로 하는 파워 리셋트 회로.
- 제1항에 있어서, 지연시간의 조정을 위해 제1지연부와의 제2지연부의 NOT 게이트(15~16, 11~14)에 동일방향으로 또다른 NOT 게이트를 추가로 직렬 접속한 것을 특징으로 하는 파워 리셋트 회로.
