The MAX6423US22-T: The reset timeout is adjustable via an external capacitor, so you set the delay to match the power-on ramp time of your downstream regulator or the oscillator start-up of the microcontroller. No fixed timeout means one BOM line serves different board variants by changing a single passive.
It is supplied in a SOT-23-4 package (TO-253AA), surface-mount. The four-pin footprint is compact — about 2.9 mm × 1.3 mm — suitable for space-constrained designs where a single supervisor sits near the processor.
