MAX16041/MAX16042/MAX16043是双/三/四通道电压监视器和排序器，采用小型QFN封装。该器件可通过逻辑输入选择固定或可调门限，并可以由小尺寸的外部电容设置排序定时，具有极大的设计灵活性。这一系列通用器件是各种多电压应用的理想选择。

当受监视的输入电压超过各自的门限值时，经过一段传输延迟或一段由电容设置的延迟之后，相应的输出变为高电平。当输入电压低于门限值时，经过一段传输延迟之后，相应的输出变为低电平。每个检测器都包含独立的使能输入，可单独关闭各自的电源就绪输出。每个检测器具有独立的漏极开路输出，支持最高28V的电压，能够与各种DC-DC调节器的关断和使能输入相连。每个检测器均可作为独立的四路监控电路工作，或者采用菊链连接，提供电源排序控制。

MAX16041/MAX16042/MAX16043也包含推挽复位功能，只有当所有被监视的电压都高于各自的门限后，才释放复位信号。复位超时可以内部确定或者外部调整。这些器件采用4mm x 4mm，TQFN封装，工作温度为-40°C至+125°C。
