Rechargeable battery protection integrated circuit device, rechargeable battery protection module using the rechargeable battery protection integrated circuit device, and battery pack

摘要

A rechargeable battery protection integrated circuit device, includes a short circuit detecting circuit configured to convert a discharge electric current of a rechargeable battery to a voltage value and detect a short circuit state of the rechargeable battery when the converted voltage value is equal to or greater than a designated short circuit detecting voltage; a discharge control terminal configured to output a control signal when the short circuit state is detected by the short circuit detecting circuit, the control signal being configured to stop a discharge of the rechargeable battery; and an overcharge detecting circuit configured to detect an overcharge of the rechargeable battery, wherein the short circuit detecting circuit includes a short circuit detecting voltage change part, the short circuit detecting voltage change part being configured to change the short circuit detecting voltage when the overcharge is detected by the overcharge detecting circuit.
