Abstract

전압 감시회로에 관한 것으로, 특히 최소의 동작 전류로서 배터리의 전압레벨을 감시하여 전압의 이상 상태를 알림하는 전압 감시회로에 관한 것이다. 상기의 전압 감시회로는 싱크전류의 공급에 응답하여 배터리로부터 출력되는 전압의 레벨을 미리 설정된 전압레벨과 비교하고, 이에 따른 알림신호(DS)를 출력하는 전압검출수단과, 상기 전압검출수단의 싱크전류단자와 제2전압단자의 사이에 접속되어 있으며 일정한 주기로 입력되는 제어신호에 응답 스위칭하여 상기 전압검출수단에 싱크전류를 공급하는 싱크전류공급수단으로 구성되어 있다. 상기와 같이 구성된 회로는 소정의 주기로 출력되는 제어신호에 응답하여 동작함으로써 최소의 전류 소비로써 배터리의 전압을 체크할 수 있게 된다.The present invention relates to a voltage monitoring circuit, and more particularly, to a voltage monitoring circuit that monitors a voltage level of a battery as a minimum operating current and reports an abnormal state of a voltage. The voltage monitoring circuit compares the level of the voltage output from the battery in response to the supply of the sink current to a preset voltage level, and outputs a notification signal DS accordingly, and the sink of the voltage detecting means. It consists of a sink current supply means connected between the current terminal and the second voltage terminal and supplying a sink current to the voltage detection means by switching in response to a control signal input at a predetermined period. The circuit configured as described above can check the voltage of the battery with minimum current consumption by operating in response to a control signal output at a predetermined period.
