Li-ion电池充电管理

XT2063是一款对单节锂电池进行恒流/恒压充电的充电管理芯片。内部包括基准，偏置、电压比较器和温度检测等模块，采用DC-DC控制模式，频率为1.5MHz，充电电流由外部电阻设置，最大可达2A。\r\n\r\n 当输入电压低于4.35V时，芯片进入SLEEP MODE工作模式，此时功耗会降低到60µA以下，同时关断充电。该芯片充电过程由涓流、恒流、恒压和再充电等过程组成，外部有2个LED可以对各种充电状态进行显示。\r\n\r\n 内置温度保护与负载短路保护，确保IC的高可靠性。\r\n\r\n 通过调节MODE端口的信号，可以选择输出电流为编程电流或者0.6倍编程电流 ● 恒流PWM电流模DC-DC控制\r\n\r\n● 恒压LDO控制\r\n\r\n● 防反灌功能\r\n\r\n● 充电电压精度为±1%，充电电流精度为±10%\r\n\r\n● 低功耗工作\r\n\r\n● 充电状态指示标志和充满状态指示标志\r\n\r\n● 自动再充电\r\n\r;
