SGM4064过压保护IC是一款充电器前端集成电路，专门用于为锂离子电池提供充电电路故障保护。SGM4064可以持续监控输入电压和电池电压。该器件的工作方式类似于线性稳压器，保持5.1V输出，输入电压高达输入过压阈值（VOVP = 6.8V）。在输入过压条件下，SGM4064立即关闭内部传输FET，将充电电路与损坏输入源断开。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。 SGM4064还可以监控其芯片温度，如果温度超过145℃则关闭。该器件的软启动和软停止功能可以有效防止涌入电流和电压尖峰，以更好的保护电池。此外，该器件最高支持1.5A 的负载电流。SGM4064的额定温度范围为-40℃至+ 85℃，可以在工业温度环境中，依然稳定可靠运行。
当过压保护IC SGM4064由处理器控制时，该器件可以向主机提供关于故障状况的状态信息，用来帮助控制器了解设备电源信息。
