BQ24095 1A、单输入、单节锂离子和锂聚合物电池充电器

描述

bq2409x系列器件是高度集成的锂离子和锂聚合物线性充电器器件，面向空间受限的便携式应用。这些设备可通过USB端口或AC适配器运行。具有输入过压保护的高输入电压范围支持低成本的非稳压适配器。

bq2409x具有单电源输出，可为电池充电。系统负载可以与电池并联放置，只要平均系统负载不能使电池在10小时安全定时器期间不能完全充电。

电池分三个阶段充电：调节，恒定电流和恒定电压。在所有充电阶段，内部控制环路监控IC结温，并在超出内部温度阈值时降低充电电流。

充电器功率级和充电电流检测功能完全集成。充电器功能具有高精度电流和电压调节环路，充电状态显示和充电终止。预充电电流和终止电流阈值通过外部电阻编程。快速充电电流值也可通过外部电阻编程。
