低成本、上电复位与看门狗控制器

MAX698/MAX699可监控微处理器(µP)和数字系统中的+5V电源。它们在上电、关断和低压掉电条件下提供持续时间至少140ms的低电平有效复位脉冲。它们无需任何外部元件，也不用进行调整，以更低的成本提高了电路可靠性。\n\n 除了MAX698的所有特性外，MAX699还提供看门狗输入以监控微处理器活动。如果看门狗输入(WDI)在1秒内未切换，则低电平有效RESET输出会变为低电平。让WDI保持开路可以禁用看门狗功能。\n\n 两款器件均采用8引脚PDIP和16引脚0.3英寸宽体小型(SO)封装，C级器件的额定温度范围为0°C至+70°C，E级器件的额定温度范围为-40 • 精密电压监控器\n\n• 电源正常/复位时间延迟\n\n• 看门狗定时器\n\n• 元件数量最少;
