Threshold voltage and reset timing
The MAX6365LKA31+T: With a threshold of 3.08V, this part is a direct fit for monitoring a 3.3V rail — the reset asserts before the supply falls below the minimum operating voltage of most 3.3V logic, giving the system time to perform an orderly shutdown. The 150ms minimum reset timeout holds the processor in reset long enough for the supply to stabilise on power-up, preventing spurious boot sequences from a glitching rail.
Package and temperature grade
Housed in an SOT-23-8 package (supplier device package SOT-23-8), the part is intended for surface-mount assembly on standard FR-4 boards — the 8-pin footprint keeps the board area small, suitable for space-constrained designs like portable or battery-backed equipment.
