PROBLEM TO BE SOLVED: To prevent overcharge, and at the same time to regenerate charge energy by providing a switch circuit that drives the primary side of a first insulating transformer, and an oscillation circuit that is controlled by a voltage comparison circuit and drives the switch circuit....
An overcharge protection circuit includes: a voltage detection portion which detects a terminal voltage of a secondary battery; and a control portion, having a normal state in which the secondary battery can be charged, a judgment execution state in which judgement as to whether the secondary batte...
PROBLEM TO BE SOLVED: To enable an overcharge protective circuit to detect the overcharging of a battery and stop the charging of the battery even when a capacitor short- circuits. SOLUTION: An overcharge protective circuit for battery is provided with a first comparing means 16 which compares th...
When overcharge protection or abnormal charge current are detected, the output voltage of OC pin changes to low voltage while OD pin remains high voltage. On the other hand, when overdischarge protection, discharge overcurrent or short-circuiting are detected, the OC pin remains high voltage ...

The control circuit controls a charge/discharge pass transistor in the pack to provide overcharge protection. An always-on trickle charge resistor insures that the controller is in operation during charging even when the cells associated with the controller are completely discharged. A Schottky diode ...
