3 to 5 Serial Cell Li-Ion / Li-Polymer Battery Protection IC with Temperature Protection

PublishTime： 2025-11-18 Manufacturer： Nisshinbo Type： Datasheet Language： English

R5654T是一款适用于3至5节锂离子/锂聚合物可充电电池组的过充、过放和过流保护集成电路，还包括短路和温度保护电路。R5654T可以通过在SEL引脚上施加一定电压来选择任意数量的电池。该IC具有低电阻RSENSE，可用于控制电路的发热，并具有细胞不平衡检测功能，可以有效检测电池之间的不平衡。当过充检测超过指定次数时，R5654T会检测到电池异常，并强制关闭充电/放电FET。
