产品概述
描述
STBC02属于高度集成式电源管理装置，其中嵌入了线性电池充电器、150 mA LDO、2个SPDT负载开关、智能复位/看门狗块以及保护电路模块(PCM)，可避免电池在故障状态下受损。
STBC02使用CC/CV算法为电池充电；可通过专用电阻独立设定快速充电和预充电电流。 会默认将终止电流设为已设定的快速充电电流值的5%，但也可改为其它值。 同样，电池浮动电压值也可通过程序设定，最高可设为4.45 V。
STBC02还具有充电器使能输入，可随时停止充电过程。
如果IN引脚未连接至有效电源（电池模式），STBC02会自动切断与电池的电源连接。
可通过外部电路（NTC热敏电阻）检测电池温度过低/过高的情况。
STBC02在装运模式下仅会从已连接电池中消耗不足10 nA的电流，因此可在最终产品保存期限内最大限度地延长电池使用寿命。 提供30um间距的覆晶封装封装。
