| Description & Applications | Protection of Lithium Ion/Lithium Polymer Battery(one cell) 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. 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. |
| 描述与应用 | 保护锂离子/锂聚合物电池（1节电池） 这是一个开发使用1节串联锂离子电池锂聚合物可充电电池的保护集成电路。它提供了一个功能，通过检测充电，过放电，放电过电流等异常，并关闭外部N沟道MOS FET进行电池保护。一个充电过电流检测功能是为充电器提供异常检测。此外，该集成电路有一个内置的定时器电路的（每个检测延迟时间），从而可以由更少的外部元件来保护电路。 |
