This is a protection IC developed for use with 1-serial cell lithium-ion/lithium polymer rechargeable batteries. It provides a function to protect the batteries by detecting overcharge, overdischarge, discharge overcurrent, and other abnormalities and turning off the external Nch MOS FET. The outputs of COUT pin(charge FET control pin) and DOUT pin(discharge FET control pin) are CMOS outputs, so that the external Nch MOS FET can be driven directly. A charge overcurrent detection function is provided for abnormal charger detection. In addition, the IC has a built-in timer circuit (for each detection delay time), so that the protection circuitly can be comprised with fewer external components. Furthermore, by setting the DS pin at VDD level, overcharge, overdischarge, discharge overcurrent can be detected, and the delay time during release can be shortened. The device returns from an overdischarge state if the battery voltage is higher than the overdischarge release voltage when a charger is connected or even not connected.
