What the 2.925V threshold means for your rail
The MAX6747KA29+T: That threshold sits just below a nominal 3.0V or 3.3V rail — it catches brownouts before the downstream logic enters an undefined state, but stays high enough to avoid nuisance resets from normal ripple. Pull it up to the supervisor's own supply or to a separate rail — the open collector handles the level translation.
Package, temperature range, and board-fit
Housed in an SOT-23-8 package — 8 pins, roughly 2.9 mm × 1.6 mm footprint. The threshold accuracy and reset timeout hold across the full temperature band — no derating needed.
