500毫安USB接口兼容的线性锂离子电池充电器电路

CN3052A是可以对单节锂离子或者锂-聚合物可充电电池进行恒流/流/恒压充电的充电器电路。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。CN3052A只需要极少的外围元器件,并且符合USB总线技术规范，非常适用于便携式应用的领域。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。调制输出电压为4.2V，精度达1%。充电电流的大小可以通过一个外部电阻调整。当输入电压（交流适配器或者USB电源）掉电时，CN3052A自动进入低功耗的睡眠模式，此时电池的电流消耗小于微安。其它功能包括输入电压过低检测，自动再充电，芯片使能输入端,电池 ·可以用USB口或交流适配器对单节锂离子或者锂-聚合物可充电电池充电\n·片内功率晶体管\n·不需要外部阻流二极管和电流检测电阻\n·输出电压4.2V，精度可达>1%\n·为了激活深度放电的电池和减小功耗，在电池电压较低时采用小电流的预充电模式\n·用户可编程的持续恒流充电电流可达500mA\n·采用恒流/恒压/恒温模式充电，既可以使充电电流最大化，又可以防止芯片过热\n·电源电压掉电时自动进入低功耗的睡眠模式\n·状态指示输出可驱动LED或与单片机接口\n·C/10充电结束检测\n·自动再充电\n·电池温度监测功能\n·芯片使能输入端\n·封装形式SOP8\n·无铅产品;
