Abstract
전원회로에 관한 것으로, 특히 백업 바테리의 상태를 판단하여 교체시기를 표시하는 회로에 관한 것이다.The present invention relates to a power supply circuit, and more particularly, to a circuit for determining a state of a backup battery and indicating replacement time.
백업 바테리의 전원을 소정의 기준전압과 비교하여 그 상태를 판단함으로써 바테리의 교체시기를 알려주어 사용자가 즉시 바테리를 교체할 수 있도록 유도하여 백업 바테리의 교체시기를 놓치거나 기타 백업 바테리의 상태변화를 감지하지 못한데서 기인하는 메모리의 파괴를 미연에 방지할 수 있도록 한다.By comparing the power of backup battery with a predetermined reference voltage and judging its status, it informs the user of the time to replace the battery and prompts the user to replace the battery immediately. This prevents the destruction of memory due to the failure of detection.
