Abstract

본 발명은 전원 절전회로에 관한 것으로, 종래의 배터리를 사용하는 전자제품에 있어서의 회로는 마이크로 컴퓨터가 항상 스탠바이 상태에 있어서만 파워온/오프 신호를 감지할 수 있기 때문에 전력소모가 커서 배터리의 사용시간이 단축되고 배터리전원 스위치 온시 마이크로 컴퓨터 주변 부하에 따른 기동전류변동으로 인해 마이크로 컴퓨터의 래치 가능성이 있는 문제점이 있었다. 본 발명은 이러한 종래의 문제점을 해결하기 위해 마이크로 컴퓨터를 사용자로부터의 파워온 신호에 의해서만 온되게 하고 평상시에는 오프상태에 있게하여 전력 소모를 줄일 수 있는 전원 절전회로를 창안한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power saving circuit. In a conventional battery-based electronic product, the power consumption is large because the microcomputer can detect a power on / off signal only when the microcomputer is always in a standby state. There is a problem that the latch of the microcomputer may be shortened due to a shortening of time and a change in starting current according to the microcomputer peripheral load when the battery power switch is turned on. The present invention has devised a power saving circuit that can reduce the power consumption by turning on the microcomputer only by the power-on signal from the user and usually in the off state to solve the conventional problems.
