描述
BD71631QWZ是一款支持2V以内低电压单节电池的充电控制IC。由于可以通过外置电阻设置充电电压、充电电流和终止电流等参数,因此可以使充电工作更大程度地发挥出电池的性能。另外,还内置有安全定时器功能和通过外置NTC热敏电阻实现的充电停止/重启功能等安全功能。产品采用的是非常适合物联网和可穿戴式设备的超小型封装(1.8mm×2.4mm×0.4mm)。日本碍子株式会社的芯片型陶瓷二次电池“EnerCera®”与ROHM电源IC的超低静态电流技术“Nano Energy™”强强联合,助力实现免维护的物联网设备。 Data Sheet 购买 * * 本产品是标准级的产品。本产品不建议使用于车载设备。
