NiCd/NiMH电池快速充电控制器; • 快速充电镍氢或镍镉电池\n\n• 电压斜率、温度和定时器快速充电截止\n\n• 为1至16节串联电池充电\n\n• 充电时为电池负载供电（线性模式）\n\n• C/4至4C快速充电速率\n\n• C/16涓流充电速率\n\n• 自动从快速充电切换到涓流充电\n\n• 线性模式功率控制\n\n• 不充电时电池消耗5µA（最大值）\n\n• 5V分流稳压器为外部逻辑供电;

MAX712/MAX713使用比最大电池电压至少高1.5V的直流电源对镍氢(NiMH)和镍镉(NiCd)电池进行快速充电。1至16节串联电池的速率充电可以高达4C。电压斜率检测模数转换器、定时器和温度窗口比较器用于确定充电完成。MAX712/MAX713通过板载+5V分流稳压器从直流电源供电。不充电时，它们从电池中消耗的最大电流为5µA。通过低侧电流检测电阻可以调节电池充电电流，同时仍然向电池负载供电。\n\n MAX712通过检测零电压斜率来终止快速充电，而MAX713则采用负电压斜率检测方案。这两个器件均采用16引脚DIP和SO封装。外部元件仅需一个外部电源PNP晶体管、阻断二极管、三个电阻和三个电容。\n\n 提供评估套件：要对该线性充电器进行快速评估，请订购MAX712EVKIT-DIP。\n\n  \n\n
