Three-rail monitoring in a SOT-23-6 footprint
The MAX6719AUTZWD3+T is a multi-voltage supervisor from Analog Devices that monitors up to three supply rails simultaneously. It asserts an active-low reset output when any monitored voltage drops below its threshold, and holds reset for a minimum of 140 ms after all rails return above threshold. The three voltage thresholds are 1.665 V, 2.313 V, and an adjustable input — covering common core, I/O, and memory rails in a single supervisor. The open-drain output allows wired-OR connection with other reset sources in the system.
Temperature grade and package for industrial designs
Housed in a 6-pin SOT-23 package (SOT-6 supplier device package), it occupies minimal board area and is compatible with standard surface-mount assembly processes. The small footprint is a deliberate trade-off: three voltage monitors in a package that would normally hold a single supervisor.
