Abstract

본 발명은 인터럽트(Interrupt) 회로에 관한것으로, 오피 엠프(OP AMP)를 이용한 히스테리시스(Hysteresis)원리를 적용하여 인터럽트(Interrupt)회로의 노이즈나 기생펄스를 최소화함으로써, 이를 전자레인지에 적용하여 전자레인지의 조리시간 카운트 및 시계기능의 타임오차를 줄일 뿐 아니라 노이즈에 의한 마이컴의 오동작을 최소화하는 데에 그 목적이 있다. 이러한 본 발명의 목적은, 반전단자(-)는 기준전압(Verf)을 비반전단자(+)는 저항을 통해 교류전원(Ej)을 인가받고 마이컴의 INT신호를 출력하며 비반전단자(+)와 INT신호의 사이에 피드백저항(nR)을 포함하는 오피엠프(POMP)로 이루어지는 인터럽트 회로를 구성함으로써 달성된다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an interrupt circuit, which minimizes noise and parasitic pulses of an interrupt circuit by applying a hysteresis principle using OP AMP, and applies it to a microwave oven, And it is an object of the present invention to minimize the malfunction of the microcomputer due to the noise as well as to reduce the time error of the counting of the cooking time and the clock function. The non-inverting terminal (+) receives the AC power (Ej) through the resistor and outputs the INT signal of the microcomputer and outputs the non-inverting terminal (+). And an operational amplifier POMP including a feedback resistor nR between the INT signal and the INT signal.
