The active-low, open-drain output lets multiple supervisors share a common reset bus — a common topology in multi-rail FPGAs and SoCs where all supplies must be valid before the processor releases from reset. The 140ms minimum reset timeout holds the processor in reset long enough for the slowest rail to stabilize, preventing brown-out or power-on glitches from reaching the core logic. ## Industrial temperature grade and compact package Housed in a 6-WFDFN package (supplier device package 6-uDFN 1.5x1), the footprint is 1.5mm x 1.0mm — small enough for space-constrained designs like handheld instruments or sensor nodes.","metaTitle":"MAX6389LT31D3+T Multi-Voltage Supervisor, Active, 6-uDFN","metaDescription":"MAX6389LT31D3+T Multi-Voltage Supervisor from Analog Devices.
