【选型】国产复位芯片SGM809B-SXN3G/TR应用于AGV中，复位延迟时间仅110μs
AGV小车控制系统中，一般会搭载MCU，在系统工作时，我们的电源信号、通信信号都有可能受到干扰。在外部干扰的影响下，有可能引起程序跑飞，系统陷入死循环。MCU都有一个最低工作电压（比如1.8V、3.3V），当电源电压跌落到低于MCU所要求的最低值时，MCU工作可能发生混乱，造成程序跑飞，引起整机死机、误动作等现象。 因此需要引入复位芯片，在系统异常时快速提供复位信号。

图2 SGM809B典型应用电路
主要性能参数：
表1 SGM809B-SXN3G/TR主要参数
由上表可知，SGM809B-SXN3G/TR供电电压范围1V~5.5V，可满足在主控3.3V供电条件下工作；300nA的工作电流可有效降低系统功耗；VCC到nRESET延迟时间110μs，在系统需要复位时提供快速响应；工作温度范围-40~125°C，可满足大多数工业应用。
封装尺寸信息：
SGM809B-SXN3G/TR为SOT-23-3封装，小尺寸规格可满足设计布局中的空间受限的要求。
综上所述，SGM809B-SXN3G/TR应用于AGV中的系统复位，在适用范围、复位响应速度、低功耗等方面具有一定优势。

【应用】复位芯片SGM821GN6G/TR用于智能锁，低功耗电源电流仅35nA，采用体积小封装SOT-23-6
当前智能锁应用十分广泛，包括门口的智能门锁、厂库门的智能挂锁等等。在一些需要移动，不方便供电的场合中，智能锁往往是电池供电，对内部器件的功耗要求就比较高。本文就此介绍了圣邦微的低功耗的复位芯片SGM821GN6G/TR在智能锁中的应用。
【应用】圣邦微复位芯片SGM706应用于机器视觉，兼具看门狗和掉电检测功能
有客户在之前设计的产品中是使用看门狗芯片和电压检测芯片，组合在一起共同实现复位功能，对体积和功耗有着较高要求。推荐圣邦微（SGMICRO）SGM706复位芯片，具备看门狗功能和掉电检测功能，体积仅5*6mm，且静态功耗电流低至50μA。
SGMICRO微处理器复位芯片选型表
SGMICRO微处理器复位芯片包含复位芯片、看门狗和计时器和电压检测器；手动复位、看门狗复位、电压排序，推挽/开漏输出，复位时间可调，最大10S复位时，复位电压可调。
