e QMPP PFM 升压型电池充电控制集成电路 +0 概述： 特点： HM4033是一款工作于4V到28V的PFM升压型电池 充电控制集成电路。HM4033内部集成有基准电压 源，＋5V电压调制单元，电感电流检测单元，电 池电压检测电路和片外N沟道MOSFET驱动电路 等，具有外部元件少，电路简单等优点。 当接通输入电源时，HM4033进入充电状态，控制 片外N沟道MOSFET导通，电感电流上升，当上升 到外部电流检测电阻设置的上限时，片外N沟道 MOSFET截止，电感电流下降，电感中的能量转 移到电池中。当电感电流下降到外部电流检测电 阻设置的下限时，片外N沟道MOSFET再次导通， 如此循环。电池电压通过电阻分压网络反馈到FB 管脚，当FB管脚电压达到1.205V(典型值)时，充电 过程结束，片外N沟道MOSFET保持截止状态。当 FB管脚电压下降到再充电阈值时，HM4033再次进 入充电状态。HM4.
