MAX708S

监视+3V电压、低成本、微处理器监控电路; • µMAX封装，小型8引脚SO封装\n\n• 精密电源电压监控器\n• 2.63V（MAX706P/R、MAX706AP/AR和MAX708R）\n\n• 2.93V（MAX706S、MAX706AS和MAX708S）\n\n• 3.08V（MAX706T、MAX706AT和MAX708T）\n\n\n\n\n• 复位时间延迟：200ms\n\n• 去抖TTL/CMOS兼容手动复位输入\n\n• 静态电流：100µA\n\n• WDI禁用特性(MAX706AP/AR/AS/AT)\n\n• 看门狗定时器：1.6s超时\n\n• 复位输出信号：\n• 仅高电平有效（MAX706P、MAX706AP）\n\n• 仅低电平有效（MAX706R/S/T、MAX706AR/AS/AT）\n\n• 高电平有效和低电平有效(MAX708R/S/T)\n\n\n\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• 8引脚表贴封装\n\n• 低至VCC = 1V时确保低电平有效RESET置位;

MAX706P/R/S/T、MAX706AP/AR/AS/AT和MAX708R/S/T微处理器(µP)监控电路减少了监控5V µP系统中的+3V至+3V电源电平所需的复杂性和元件数量。与单独的IC或分立元件相比，这些器件显著提高了系统的可靠性和准确性。\n\n MAX706P/R/S/T和MAX706AP/AR/AS/AT监控电路提供以下四个功能：\n\n 1) 启动、关断和掉电情况下的复位输出。 2) 如果看门狗输入在1.6秒内未触发，则独立看门狗输出会变为低电平。 3) 1.25V阈值检测器，用于电源故障警告、低电池电量检测或用于监控主电源以外的电源。 4) 一个低电平有效的手动复位输入。 MAX706R/AR、MAX706S/AS和MAX706T/AT之间只有复位阈值电压电平有所不同，分别为2.63V、2.93V和3.08V。所有器件都具有低电平有效复位输出信号。除了复位输出信号为高电平有效外，MAX706P/AP与MAX706R/AR相同。当WDI输入悬空或连接到低漏电三态输出的高阻态时，MAX706AP/AR/AS/AT的看门狗定时器功能禁用。\n\n MAX708R/S/T提供的功能与MAX706R/S/T和MAX706AR/AS/AT相同，只它们没有看门狗定时器，而是提供低电平有效RESET和RESET输出。与MAX706一样，带有R、S和T后缀的器件的复位阈值分别为2.63V、2.93V和3.08V。\n\n 这些器件采用8引脚SO、DIP和µMAX®封装，并在整个温度范围内提供额定性能。\n\n  \n\n
