在工业领域中，HMI触摸屏被广泛地用作人与机械设备交互的窗口，用来连接各类PLC、传感器等。同时随着物联网的不断发展，HMI成了机械设备连接物联网的关键媒介，HMI是“物物互联”不可缺少的一部分。对于HMI的设计者来说，选择一款低功耗的微控制器电压监测芯片是至关重要的，本文推荐圣邦微（SGMICRO）的微控制器电压监测芯片SGM811-SXKA4/TR用于HMI设计中，静态电流典型值13μA。

图1为SGM811-SXKA4/TR的典型应用框图，静态电流典型值13μA，SOT-143封装，工作温度-40—125℃。

圣邦微推出的微控制器电压监测芯片SGM811-SXKA4/TR，应用在HMI上有以下优势：

1、输入电压范围-0.3—6.0V，宽电压范围，复位电压可根据MCU的要求进行选定；

2、静态电流典型值13μA，可满足低功耗的需求；

3、复位阙值电压典型值2.93V，精度±2.49%，温漂系数30ppm/℃，无需做任何调整，可以保证系统稳定性；

4、工作温度-40—125℃，车规级温度范围，可满足HMI的工作范围；

5、上电复位持续时间典型值240ms，在该时间内监控电路保持重置状态，直到状态稳定，可以提高电路稳定性，防止误触发；

6、 SOT-143封装，为常用封装，可与市面上相同功能的品牌进行完全兼容替代，对品牌的替换更有优势。

综上所述，圣邦微（SGMICRO）的微控制器电压监测芯片SGM811-SXKA4/TR非常适合应用在HMI中。
