Abstract

본 발명은 사용상의 부주의로 인하여 CPU의 구동전압이 잘못인가되어 장시간 사용에 따른 회로소자의 손상을 미연에 방지코자한 키보드 콘트롤러를 이용한 씨피유 전압 검출장치에 관한 것이다.The present invention relates to a CPI voltage detecting device using a keyboard controller designed to prevent damage to a circuit device caused by a long time use due to an incorrect driving voltage of a CPU due to careless use.

종래에는 컴퓨터의 주요부품인 CPU가 구동할 때 전압차이가 크면 시스템 동작이 전혀 이루어지지 않게 될뿐만 아니라 전압차가 심한 상태로 시스템을 장시간 사용할 때에는 회로소자의 손상을 초래하게 되는 문제점이 있었다.Conventionally, when the CPU, which is a main component of a computer, has a large voltage difference, system operation is not performed at all, and there is a problem that damages a circuit element when the system is used for a long time with a severe voltage difference.

이를 개선코자하여 본 발명은 저전력 시스템 개발에 부응하여 컴퓨터의 주요 부품인 CPU의 구동전압이 소정 전압레벨(DC5V)에서 DC3.3V 또는 DC3.45V로 저하됨에 따라 DC3.3V용 CPU를 DC3.45V전원에서 사용할 때 야기될 수 있는 시스템의회로소자의 손상을 미연에 방지코자한 것이다.In order to improve this, the present invention responds to the development of a low-power system, and as a result, the driving voltage of the CPU, which is a major component of the computer, is reduced to DC3.3V or DC3.45V at a predetermined voltage level (DC5V). This is to prevent damage to the circuit elements of the system that may be caused when using the power supply.
