5V及3.3V MicroMonitor

DS1814 5伏MicroMonitor和DS1819 3.3V MicroMonitor可监视微处理器的三个重要条件：电源、软件执行和外部覆盖。首先，精密的温度补偿基准电压源和比较器电路监控VCC的状态。当出现超出容差的情况时，会产生内部电源故障信号，强制复位为有效状态。当VCC返回到容差范围内的条件时，复位信号将保持有效状态至少140ms，以便电源和处理器稳定下来。DS1814/DS1819“A”和“C”执行按钮复位控制。它们对按钮输入进行去抖处理，并生成140ms（最小值）宽度的有效复位脉冲。DS1814/9“A”和“B”版本执行看门狗功能。看门狗是一个内部定时器，如果选通输入没有每1 • 停止并重新启动失控的微处理器\n\n• 在电源瞬变期间对微处理器进行限制\n\n• 发生电源故障后自动重启微处理器\n\n• 监控按钮的外部覆盖情况\n\n• 精度为5%、10%或20%（仅限3V）的微处理器电源监控\n\n• 无需分立元件\n\n• 20%容差，适用于3.0V系统\n\n• 与MAX823/24/25产品引脚和功能兼容\n\n• 低成本SOT-23-5封装\n\n• 工业温度范围：−40°C至+85°C;
