It produce aregulated output voltage from a 2.7V to 4.5Vinput. Low external parts count (one flyingcapacitor and two small bypass capacitors atVIN and VOUT) make the HE9119A ideallysuited for small, battery-powered applications.The HE9119A have thermal shutdowcapability and can survive a continuous shortcircuit from VOUT to GND. A low currentshutdown feature disconnects the load from VINand reduces quiescent current to <1uA.The HE9119A is available in the indu

最短，当电池接近完全饱和，大概在 4.15V 左右， 将自动转换为恒压(CV)的充电周期。在恒压充电周期， 充电电流将会减小使电池逐渐饱和而没有过饱和的危险，这是必要的，因为锂电池不能过饱和 50mV，否则就有爆炸 的危险。
