概览

MC34164 系列为欠电压感应电路，专门用作重置控制器，适用于较长电池寿命至关重要的、基于便携式微处理器的系统。此类器件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。MC34164 系列具有禁带参考、带精确阈值和内置磁滞以防错误重置运行的比较、能够汲取 6.0 mA 以上电流的开路集极重置输出，保证运行电压低至 1.0 V 输入，且具有极低待机电流。此类器件采用 3 引脚 TO-226AA、8 引脚 SO-8 和 Micro-8 表面贴装封装。NCV 器件采用 SO-8 封装。应用包括设备、汽车、消费品和工业设备中使用的 3.0 或 5.0 V MPU/逻辑电源直接监控。

  • Temperature Compensated Reference
  • Monitors 3.0 V (MC34164-3) or 5.0 V (MC34164-5) Power Supplies
  • Precise Comparator Thresholds Guaranteed Over Temperature
  • Comparator Hysteresis Prevents Erratic Reset
  • Reset Output Capable of Sinking in Excess of 6.0 mA
  • Internal Clamp Diode for Discharging Delay Capacitor
  • Guaranteed Reset Operation With 1.0 V Input
  • Extremely Low Standby Current: As Low as 9.0 µA
