MAX6412-MAX6420低功耗微处理器监控电路可监视1.6V至5V的系统电压。一旦V_CC电源电压或RESET IN跌落到它的复位门限、或手动复位输入被置位，这些器件将产生复位信号。当V_CC和RESET IN上升到复位门限以上、手动复位输入被释放时，复位输出将继续保持一个复位延时周期的时间。复位延时可由外部电容设置，提供了更多的灵活性。

MAX6412/MAX6413/MAX6414提供1.575V至5V的固定复位门限，级差约为100mV，带有手动复位输入。MAX6415/MAX6416/MAX6417提供可调节的复位输入，监视电压可低至1.26V；MAX6418/MAX6419/MAX6420提供一个固定输入和一个可调输入，用于监视双电压系统。

MAX6412/MAX6415/MAX6418具有低有效、推挽式复位输出；MAX6413/MAX6416/MAX6419具有高有效、推挽式复位输出；MAX6414/MAX6417/MAX6420则具有低有效、漏极开路复位输出。所有这些器件都采用SOT23-5封装，工作于-40°C至+125°C温度范围。
