The SOT-23-8 package is small enough for space-constrained designs but still hand-solderable with practice. If your board lives in a heated office or consumer gadget, the temperature range is overkill — but it means the part won't be the weak link if the environment gets hot or cold.
You can specify it into a new design today without worrying about obsolescence mid-run.
Yes — the 2.313V threshold is designed for a 2.5V rail. It will assert reset when the supply drops below that level, protecting 2.5V logic.
No — the 2.313V threshold is too low for a 3.3V rail. The supervisor would never trip under normal 3.3V operation. Use a threshold variant rated for 3.3V monitoring instead.
Push-pull, totem-pole output — it drives the reset line high or low without an external pull-up resistor.
The MAX6752KA24 has a different threshold voltage. The MAX6752KA23 is set for 2.313V; check the MAX6752KA24's threshold to confirm compatibility. Both share the same SOT-23-8 package and pinout, so if the thresholds match your rail, it's a drop-in swap.
