客户需要一款电源芯片用于MCU复位，输入电压范围必须包含3.3~5V，向客户推荐国产品牌圣邦微的SGM893B。SGM893B是具有高精度检测的低功耗电压检测器，工作电压1~6V，工作温度-40~125℃。SGM893B提供了极大的灵活性，具有可调的阈值，可从1V到5V，增量为0.1V，客户的需求为2.5V，SGM893B符合客户的需求。

表1 SGM893B主要参数

VOUT引脚是一个具有有源低电平复位的N通道开路漏极输出。SGM893B中有一个有效的低手动复位输入（nMR）引脚，非常适合用于电源排序、复位排序和电源切换应用。客户使用该器件用于MCU复位。当nMR被拉低时，即使VIN电压高于出厂设置电压(VDET + VHYs) ，VOUT也会被强制降低。当nMR返回到逻辑高电平，VIN电压超过阈值电压(VDET + VHYs)后，复位延迟时间（t_D）过后，VOUT解除警报。

SGM893B有绿色SOT-23-5和UTDFN-1×1-4L封装，客户选择封装较小的UTDFN-1x1-4L。综上介绍，SGM893B通过了客户的评估。
