电压监控器,欠电压感应电路

Favorite

概览

MC33064/MC34064 是一款欠电压感应电路,特别适合用作基于微处理器的系统中的重置控制器。它为设计人员提供了一种经济的方案,通过一个外部电阻实现低电压检测。MC33064/MC34064 具有封装内微调禁带参比,以及带有精确阈值的比较器和内置的迟滞,可防止错误重置运行。开路采集器重置输出能够汲取超过 10 mA 的电流,在低至 1.0 V 的输入下可以保证运行且待机电流低。MC 器件采用 3 引脚 TO-226AA、8 引脚 SO-8、微型 8 和 5 引脚 SOT-23/TSOP-5 表面贴装封装。NCV 器件采用 SO-8 和 TO-226AA 封装。应用包括设备、汽车、消费品和工业设备中使用的 5.0 V MPU/逻辑电源直接监控。
