Supervisor for low-voltage rails — 1.67V threshold
The Analog Devices MAX6824WUK+T is a simple reset/power-on reset supervisor IC that monitors a single voltage rail. Its 1.67V threshold is sized for low-voltage core supplies.
140 ms reset timeout — what it buys you
That's margin against a brown-out or a slow-ramping supply. For a board that powers up from a regulated rail with known rise time, this timeout is standard; for a design with a large input capacitor or a long power-good delay, check that 140 ms is enough headroom before the processor expects its reset released.
The SOT-23-5 package is a small five-pin surface-mount footprint that fits tight layouts.
It is ROHS3 compliant.
