Three-rail monitoring in a single SOT-23-6
The MAX6355LSUT-T is a multi-voltage supervisor from Analog Devices that monitors three supply rails simultaneously — 2.93 V, 4.63 V, and one adjustable threshold — with a single active-low reset output. The open-drain output pulls low when any monitored voltage falls below its threshold and holds the reset state for a minimum of 100 ms after all rails recover, giving the downstream system time to stabilize before releasing the processor. This consolidates three discrete supervisor ICs or resistor-divider comparators into one SOT-23-6 package, saving board area and reducing the component count on a multi-rail power tree.
