Abstract

본 발명은 기존의 백업(Back up)배터리를 사용하지 않고 저전압 검출장치를 사용하여 제품 소형화 및 코스트 절감화를 도모함으로써 포터블 장치에 채용하기에 적합하도록 한 시간 저장회로에 관한 것이다.The present invention relates to a time storage circuit that is suitable for use in a portable device by miniaturizing a product and reducing a cost by using a low voltage detection device without using a conventional back up battery.

종래 기술은 시계기능이 구비된 장치 특히 포터블 장치에서 전원을 교환할 경우 장치가 리세트 상태가 되어 시간을 다시 조정해야만 하는 불편을 제거하기 위해 백업 배터리를 사용하기 때문에 이로인해 장치의 부피가 커짐은 물론 제품 코스트가 상승되는 문제점이 있었다.The prior art uses a backup battery to eliminate the inconvenience of having to adjust the time again when the device is reset when power is exchanged in a device equipped with a clock, especially a portable device. Of course, there was a problem that the product cost is rising.

이를 개선코자하여 본 발명은 고가이면서 부피가 큰 백업 배터리의 사용을 배제하고 그 대신에 저전압 검출장치를 사용하여 시간 저장을 용이하게 할 수 있는 시간 저장회로를 제공코자 한 것이다.To improve this, the present invention aims to provide a time storage circuit that can eliminate the use of expensive and bulky backup batteries and instead facilitate time storage using a low voltage detection device.
