Li-ion电池充电管理

XT2052是可以对单节可充电锂电池进行恒流/恒压充电的充电器电路芯片。该器件内部包括功率晶体管，应用时不需要外部的电流检测电阻和阻流二极管。XT2052只需要极少的外围元器件，并且符合USB总线技术规范，非常适合于便携式应用的领域。\r\n\r\n 热调制电路可以在器件的功耗比较大或者环境温度比较高的时候将芯片温度控制在安全范围内。内部固定的恒压充电电压为4.2V，充电电流通过一个外部电阻设置。当输入电压（交流适配器或者USB电源）掉电时，XT2052自动进入低功耗的睡眠模式，此时电池的电流消耗小于0.1µA。内置防反灌保护电路，当电池电压高于输入电压时，自动关闭内置功率MOSFET。 ● 可编程，充电电流可达1.0A\r\n\r\n● 不需要外部MOSFET、传感电阻和阻流二极管\r\n\r\n● 小尺寸，实现对锂离子电池的完全线形充电管理\r\n\r\n● 恒流/ 恒压运行和热度调节使得电池管理效率最高，没有热度过高的危险\r\n\r\n● 从USB接口管理单片锂离子电池\r\n\r\n● 充电状态指示标志和充满状态标志\r\n\r\n● 1/10充电电流终止\r\n\r\n● 自动再充电\r\n\r\n● 停止工作时提供40mA电流\r\n\r\n● 2.9V涓流充电阈值电压\r\n\r\n● 软启动限制浪涌电流\r\n\r\n● 当拔掉VIN时，IC不消耗电池能量\r;
