【应用】国产复位芯片SGM809B-SXN3G/TR用于彩屏温控器，最小上电脉冲时延低至150ns
对于很多电子设计，尤其是医疗，军工，工业控制等设备来说，在面对突发故障时的保护和复位都是一项必须设计的功能，温控器作为一种典型的工业控制设备，故障检测和重启功能也是必不可少的。
圣邦微的国产微处理器监控芯片系列，集成度高，性价比好，是进行复位功能设计的优秀选择之一，在此选择的具体型号是SGM809B-SXN3G/TR。以下是温控器的结构框图：
SGM809B-SXN3G/TR是一款圣邦微的微控制器检测与复位集成芯片，在上电状态下，内部计时器维持一个240ms的重置断言，它使微处理器处于重置状态，直到条件稳定。 而在面对下电，甚至是降压停电的条件，即使当VCC低至1V时，复位输出仍可工作。并且在面对突发式故障时，SGM809B-SXN3G/TR复位比较器内部的故障免疫可以保护它免受VCC上的快速瞬变，从而进行正常重置。最后，复位芯片作为一种长时间处于检测待机状态下的芯片，其待机功耗对整体系统的平均功耗影响是较大的，而在待机检测状态下，SGM809B-SXN3G/TR有低至300nA的静态电流，对降低温控器整体功耗有着较为显著的作用。
