MAX16000–MAX16007是低压、四/六/八路电压µP监控电路，采用小尺寸薄型QFN封装。这些器件可为复杂的多电压系统提供监控功能。MAX16000/MAX16001/MAX16002可监视4路电压，MAX16003/MAX16004/MAX16005可监视6路电压，而MAX16006/MAX16007可监视8路电压。

MAX16000/MAX16001/MAX16003/MAX16004/MAX16006为监视的每路电压提供独立的输出。当任一路被监视电压跌落至其门限以下，或触发手动复位输入时，MAX16001/MAX16002/MAX16004–MAX16007将会产生复位输出，当所有电压都恢复至高于其门限以上且未触发手动复位输入时，复位输出在复位超时周期内仍保持有效。最小复位超时内部设置为140ms，也可通过外部电容进行调节。

所有开漏极输出内部均有30µA上拉电路，无需外部上拉电阻。但每一路输出都可由高达5.5V的外部电压来驱动。此外，该系列器件还具有手动复位输入，一个可将输入门限容差设置为5%或10%的引脚，以及可在状态测试过程中解除所有报警输出的状态控制功能。

MAX16001/MAX16002/MAX16004–MAX16007提供一个看门狗定时器，当时间超出看门狗超时周期(典型值1.6s)时，产生/RESET或独立的看门狗输出(MAX16005)。可通过悬空该输入禁用看门狗定时器。

这些器件采用12、16、20和24引脚薄型QFN封装(4mm x 4mm)，并可工作在-40°C至+125°C温度范围内。
