微处理器监控电路

MAX690A/MAX692A/MAX802L/MAX802M/MAX805L监控电路减少了微处理器(µP)系统中的电源监控和电池控制功能所需的复杂性和元件数量。与单独的IC或分立元件相比，它们显著提高了系统的可靠性和准确性。\n\n 这些器件提供四个功能：1) 启动、关断和掉电情况下的复位输出。2) CMOS RAM、CMOS µP或其他低功耗逻辑的备用电池切换。3)如果可选的看门狗定时器在1.6秒内未切换，则提供复位脉冲。4) 1.25V阈值检测器，用于电源故障警告、低电池电量检测或+5V以外电源的监控。\n\n 这些器件的复位电压阈值电平和复位输出有所不同。MAX69 • 精密电源电压监控器：\n• MAX690A/MAX802L/MAX805L为4.65V\n\n• MAX692A/MAX802M为4.40V\n\n\n\n\n• 复位时间延迟：200ms\n\n• 看门狗定时器：1.6s超时\n\n• 备用电池电源开关\n\n• 静态电源电流：200µA\n\n• 备用电池模式下的静态电源电流为50nA\n\n• 电压监控器，监控有无电源故障或低电池电量警告\n\n• 电源故障精度高达±2% (MAX802L/M)\n\n• 低至 VCC = 1V 时确保低电平有效RESET置位\n\n• 8引脚SO和DIP封装;
