具有过压、过温保护的充电保护芯片SGM4062，为低功耗手持设备充电提供有效保护
SG Micro Corp(圣邦微电子) （北京）股份有限公司（以下简称圣邦微）是一家专注于高性能、高品质模拟集成电路研发和销售的半导体公司。圣邦微的通用模拟IC产品性能优良、品质卓越，可广泛应用于智能手机、PAD、数字电视、DVD、数码相机、笔记本电脑、可穿戴式设备、各种消费类电子产品以及车载电子、工业控制、医疗设备、测试仪表等众多领域。
SGM4062是圣邦微推出的一款具有LDO模式的过压保护的Li +充电器前端保护IC。该集成电路主要用于充电器前端，具有锂电池过压检测功能、启动过流保护功能主要是为锂离子电池提供充电电路故障保护。SGM4062主要是通过持续监控输入电压和电池电压来实现对电池的故障保护。下图为SGM4062两种封装图：
图1 SGM4062 TDFN-2×2-8L和MSOP-8封装图
SGM4062 Li +充电器前端保护IC的工作方式类似于线性稳压器。在输入电压高达输入过压阈值（VOVP = 6.8V）时，SGM4062依然可以稳定保持5.1V输出。在输入过压条件下，SGM4062会立即关闭内部传输FET，将充电电路与损坏输入源断开，从而保护电池不被过压损伤。此外，如果在充电时电池电压上升到不安全的水平，则会从系统中移除电源，更加有效保护电池。 SGM4062还可以监控其芯片的温度，当芯片温度超过145℃时会关闭电源输入，以保护芯片不被烧坏。当SGM4062由处理器控制时，SGM4062可以向主机提供关于故障状况的状态信息。优越的性能让其可以应用于智能手机、掌上电脑、MP3和低功耗手持设备等产品。
图2 SGM4062 典型应用电路
SGM4062充电器前端IC采用绿色TDFN-2×2-8L和MSOP-8（裸露焊盘）封装，额定温度范围为-40℃至+ 85℃，可以适用于严苛的工业环境。
