hm4054h

 HM4054H 描述 / Descriptions HM4054H是一款完整的单节锂离子电池采用恒定电流/恒定电压线性充电器。其SOT封装与较 少的外部元件数目使得HM4054H成为便携式应用的理想选择。HM4054H可以适合USB电源 和适配器电源工作。 The HM4054H is a complete constant-current/constant voltage linear charger for single cell lithium-ion batteries. Its Thin SOT package and low external component count make the HM4054H ideally suited for portable applications. Furthermore, the HM4054H is specifically designed to work within USB power specifications. 由于采用了内部PMOSFET架构，加上防倒充电路，所以不需要外部检测电阻器和隔离二极管。热反 馈可对充电电流进行调节，以便在大功率操
