锂电池充电管理

采用 ThinSOT 封装并具终止功能的线性锂离子电池充电器

LTC®4056 是一款低成本、单电池、恒定电流 / 恒定电压锂离子电池充电器控制器，其具有一个可编程终止定时器。当与少量外部组件相结合时，LTC4056 可打造一种适用于单节锂离子电池且非常小巧的独立型充电器。\n\n 充电电流和充电时间分别利用单个电阻器和电容器在外部设定。LTC4056 充电至一个准确度达 ±0.6% 的最终浮动电压。手动停机是通过把 TIMER/SHDN 引脚接地来完成的，而拿掉输入电源则自动地将 LTC4056 置于一种睡眠模式。停机模式和睡眠模式从电池消耗的电流接近于零；停机模式将电源电流减小至 40µA。\n\n 对输出驱动器提供了电流 • 具终止功能的独立型锂离子电池充电器\n\n• 可编程终止定时器\n\n• 无需检测电阻器或隔离二极管\n\n• 适合 USB 供电型充电\n\n• 欠压充电电流限制\n\n• 准确度达 ±0.6% 的预设充电电压\n\n• 可编程充电电流：200mA 至 700mA\n\n• 充电周期缩短的自动再充电\n\n• 针对过流 / 过热的自我保护能力\n\n• 在停机模式中电源电流为 40µA\n\n• 停机模式中的电池消耗电流可忽略不计\n\n• 低电量电池充电调节 (涓流充电)\n\n• CHRG 状态输出包括 AC 接入\n\n• PCB 总解决方案面积仅为 75mm2 (700m;
