Six-rail supervisor in a 5×5 QFN
The MAX6885ETP+ is a multi-voltage supervisor from Analog Devices that monitors six independent supply rails simultaneously, with six selectable threshold combinations to match common core, I/O, and auxiliary voltages in a system. Each monitored channel can assert either an active-high or active-low reset, and the output stage is configurable as open-drain or push-pull — so the same part serves both wired-OR and direct-drive reset topologies without an external pull-up or inverter. The reset timeout period is adjustable via an external capacitor, giving the designer control over the power-good hold-off time after all rails are valid.
