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.","metaTitle":"MAX6421XS29+T Simple Reset/Power-On Reset, 2.925V, SC-70-4","metaDescription":"MAX6421XS29+T active supervisor IC, 2.925V threshold, active-low reset, SC-70-4.
