M68732L中文资料

简单的限流开关模式Li +电池充电控制器

--------------------------------------------------------------------------概述

低成本的MAX1873R/S/T提供所有功能需要对高达4A或以上的2 - ，3 - 或4 - 系列的锂离子电池进行简单而有效的充电。它提供调节充电电流和电压，少于±0.75％时，总电压在

电池端出现错误。在降压的DC - DC配置下，外部P沟道MOSFET有效地为电池充电，这是

低成本的设计。

MAX1873R/S/T使用两个控制回路调节电池电压和充电电流，一起工作的两个控制回路在电

压和电流调节之间顺利转换。一个额外的控制回路限制电流来自输入端，可以使AC适配器

尺寸和成本最小化。模拟电压还提供其输出正比于充电电流，以便ADC或微控制器可以监控

充电电流。

在多化学充电器设计时，MAX1873也可能被用来作一个有效的有限电流源对镍镉或镍氢电池

充电。MAX1873R/S/T采用节省空间的16引脚QSOP封装是可用的。使用评估板

（MAX1873EVKIT），可以帮助减少设计时间。
