Abstract

본 발명은 마이콤에 인가되는 전류가 일시적으로 부족하게 될 때에도 마이콤이 오동작하지 않도록 하기에 적합한 마이콤의 오동작 방지 장치에 관한 것으로, 종래에는 전원 라인에 과부하가 걸리거나 다수의 전기제품들이 일시에 동작될 때, 일시적으로 전류가 부족하게 됨으로써 전압이 높아져서 마이콤의 전원단에 전원인가와 마이콤의 리세트단에 전원인가가 동시에 이루어져, 마이콤이 리세트되지 않음에 의해 마이콤이 오동작하게 되는 결점이 있었으나, 본 발명에서는 지연부(50)에 의한 지연과 저항(R11) 및 캐패시터(C11)에 의해 형성되는 시정수만큼의 지연이 이루어진 후에 마이콤(40)의 리세트단(RESET)에 전원 발생부(30)이 출력전원이 인가되므로써 이상 상태 등에 의해 전원 발생부(30)의 출력전압에 따른 전류가 줄어들어도 마이콤(40)이 정상적으로 리세트될 수 있는 것이다.The present invention relates to a microcomputer malfunction prevention device suitable for preventing the microcomputer from malfunctioning even when the current applied to the microcomputer temporarily becomes short. In the related art, a power line may be overloaded or a plurality of electrical appliances may At this time, the shortage of current caused the voltage to increase, and at the same time, power was applied to the power supply terminal of the microcomputer and power was applied to the reset terminal of the microcomputer simultaneously. In the present invention, after the delay by the delay unit 50 and the delay by the time constant formed by the resistor R11 and the capacitor C11 are made, the power generation unit 30 is reset at the reset end of the microcomputer 40. Since the output power is applied, even if the current according to the output voltage of the power generating unit 30 decreases due to an abnormal state or the like, the microcomputer 40 is normally operated. It can be reset to.
