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
25. 2016 1 单片具有热调节功能的微型线性电池管理芯片 ■ 产品概述 HE4054B 是一个完善的单片锂离子电池恒流/恒压线形 电源管理芯片。它薄的尺寸和小的外包装使它便于便携应 用。更值得一提的是,HE4054B
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。
