Abstract
재충전가능 배터리 팩의 과방전 또는 과전류가 검출되는 경우, 팩의 VDD와 VSS간의 출력 전압과 출력 전류가 제로로 되며, 이 경우 상기 배터리 팩과 접속된 장치 또는 로드가 데이터를 상실하거나 오동작을 초래한다. 재충전가능 배터리 팩(1)에 있어서, 2차 배터리에 걸리는 전압 V1이 임의의 검출 전압 V2 이하로 감소하는 경우 프리 엔드(pre-end) 신호출력회로(5)가 프리 엔드 출력신호를 발생하는데, 이 신호는 과충전/과방전 및 과전류제어회로(3)가 상기 2차배터리 전압 V1이 과충전방출 전압 V3 이하로 감소된 것을 검출할 때까지 지속되게 된다. 상기 제어회로(3)의 출력신호에 의해 상기 스위치 회로(4)가 상기 2차 배터리의 방전을 정지한다. 따라서 장치 또는 부하는 데이터를 세이브할 수 있거나 달리 동작할 수 있다.When an overdischarge or overcurrent of a rechargeable battery pack is detected, the output voltage and output current between the VDD and VSS of the pack become zero, in which case the device or load connected to the battery pack loses data or causes malfunction. . In the rechargeable battery pack 1, the pre-end signal output circuit 5 generates a pre-end output signal when the voltage V1 applied to the secondary battery decreases below an arbitrary detection voltage V2. This signal is continued until the overcharge / overdischarge and overcurrent control circuit 3 detects that the secondary battery voltage V1 has decreased below the overcharge discharge voltage V3. By the output signal of the control circuit 3, the switch circuit 4 stops discharging the secondary battery. Thus, the device or load can save data or otherwise operate.
