QX4054

线性锂电充电控制器; • 电源电压：4.5 V~6.0V\r\n\r\n• 可编程充电电流：最高700mA\r\n\r\n• 预设4.2V充电电压的精度：±1%\r\n\r\n• 涓流充电阈值电压：2.9V\r\n\r\n• 过热保护：保证快速而安全的充电\r\n\r\n• 软启动：有效限制冲击电流\r\n\r\n• 无需外接MOS管、感应电阻和二极管\r\n\r\n• 可从USB口直接给电池充电;

QX4054 是一款完整的单节锂离子电池恒流恒压线性充电控制器，只需要极少的外接元件，便能适用于便携式产品的应用，而且QX4054 是专门为USB电源充电而设计的\r\n\r\n QX4054根据电池电压的不同可分别有涓流充电，恒流充电和恒压充电等三种充电模式。涓流充电模式的充电电流为满充电电流的1/10；恒流充电模式的充电电流为满充电电流；恒压充电模式的充电电压被固定在4.2V，在电池电压达到满电量电压并且充电电流降至满充电电流的1/10时，QX4054将自动停止充电。满充电电流是通过一个外接电阻来设定的。\r\n\r\n QX4054还内置了睡眠模式、关断模式、充电电流监测、过压保护、过热保护、自动再充电、工作状态指示等功能。\r\n\r\n QX4054采用SOT-23-5封装
