Abstract

1. 청구 범위에 기재된 발명이 속한 기술 분야1. Technical field to which the invention described in the claims belongs

충전용 베터리를 사용하는 시스템에서 과전압 보호회로.Overvoltage protection circuit in systems using rechargeable batteries.

2. 발명이 해결하려고 하는 기술적 과제2. Technical Challenges to be Solved by the Invention

베터리가 장착되지 않은 경우에는 충전기로부터 제공되는 과전압이 그대로 시스템회로에 제공되어 상기 시스템회로를 구성하는 부품이 파손으로 인한 시스템 전체를 사용할 수 없었다.When the battery is not mounted, the overvoltage supplied from the charger is directly supplied to the system circuit, so that the system constituting the system circuit can not use the entire system due to the breakage.

3. 발명의 해결 방법의 요지3. The point of the solution of the invention

충전전압을 공급하는 충전기와, 상기 충전기로부터 공급되는 충전전압에 의해 충전되어 시스템의 동작 전압을 공급하는 베터리를 구비한 충전용 베터리를 사용하는 시스템에서, 상기 베터리 양단의 전압에 따라 동작 전압의 공급 여부를 제어하는 과전압 차단부를 통하여 과전압으로부터 시스템을 보호하는회로.In a system using a rechargeable battery having a charger that supplies a charging voltage and a battery that is charged by a charging voltage supplied from the charger and supplies an operating voltage of the system, Circuit that protects the system from overvoltage through an overvoltage shutoff that controls whether the system is overvoltage.

4. 발명의 중요한 용도4. Important Uses of the Invention

충전용 베터리를 사용하는 전자 제품.Electronic products that use rechargeable batteries.
