数据: bq2408x 750-mA Single-Chip Li-Ion and Li-Pol Charge Management IC With Thermal Regulation 数据表
bq2408x系列是高度集成的锂离子和锂聚合物线性充电器,针对空间受限的便携式应用。 bq2408x系列提供多种保护功能和功能选项,同时仍在小型封装中实现完整的充电系统。电池分三个阶段充电:调节,恒定或热调节电流和恒定电压。根据最小电流终止充电。内部可编程充电定时器为充电终止提供备用保护功能,并在热调节阶段动态调整。如果电池电压低于内部阈值,bq2408x会自动重启充电;当移除外部输入电源时,将设置睡眠模式。该器件系列的多个版本可以在底座充电器或终端设备中轻松设计bq2408x,同时使用低成本或高端AC适配器。
