It monitors two independent voltage rails, with one threshold fixed at 3.08V and the second adjustable via an external resistor divider. The reset timeout is a minimum of 140 ms, giving the downstream processor time to stabilize after the supply rails come into regulation. Surface-mount assembly on a standard SC-70 footprint keeps the board area small. ## Active lifecycle and supply The part ships in bulk packaging (tube or tray, not tape-and-reel), which is typical for small-quantity engineering samples or repair-stock orders. If reel packaging is needed for automated pick-and-place, confirm the reel option with your distributor at quote time.","metaTitle":"MAX6388XS31D3+ Power Supply Monitor, 2-Volt","metaDescription":"MAX6388XS31D3+ from Analog Devices: dual-voltage power supply monitor, active high push-pull reset, 140ms timeout, SC-70-4.

The push-pull output drives the reset line directly without an external pull-up resistor, simplifying the connection to the processor's reset input. The reset stays asserted for a minimum of 140 ms after the supply recovers."},{"question":"What voltages does the MAX6388XS31D3+ monitor?","answer":"It monitors two voltages: one fixed threshold at 3.08V and a second adjustable threshold set by an external resistor divider. This allows one rail to be precisely monitored at 3.08V (e.g., a 3.3V supply) while the second rail can be tailored to any lower voltage the design requires."},{"question":"What package does the MAX6388XS31D3+ come in?","answer":"It is supplied in a 4-lead SC-82A (SOT-343) package, also referred to as SC-70-4. The footprint is compact, measuring approximately 2.0 mm x 2.1 mm, suitable for space-constrained designs.
