Product details

2.925V threshold, SC-70-4 supervisor

The MAX6421XS29+T: It monitors a single supply rail and asserts reset when the voltage drops below the threshold, holding it low for an adjustable timeout period after recovery. Housed in the SC-70-4 (SC-82A, SOT-343) package, this part is suited for space-constrained PCB layouts where a small footprint supervisor is needed for a 3.3V or 3.0V rail.

Active production, ROHS3 compliant

Supplied in tape and reel or cut tape, the part is surface-mount ready for automated pick-and-place assembly. Store the reels dry — the SC-70-4 package is moisture-sensitive per JEDEC level 1, but a dry-bake before reflow is still good practice if the seal is broken.

Frequently asked questions

What is MAX6421XS29+T's listed reset polarity?

The reset output is active-low, meaning the reset signal goes low when the monitored voltage falls below the 2.925V threshold and remains low for the adjustable timeout period after recovery.
