ANALOG DEVICES ADM811/ADM812 handbook (1)
The ADM811/ADM812 are reliable voltage monitoring devices suitable for use in most voltage monitoring applications. The ADM811/ADM812 are designed to monitor five different voltages, each allowing for a 5% or 10% degradation of standard PSU voltages before a reset occurs. These voltages have been selected for the effective monitoring of +3 V, +3.3 V, and +5 V.

Questions answered in these manuals
What does the manual reset input do?
The manual reset (MR) pin is an active‑low debounced input that ignores pulses shorter than 100 ns and accepts pulses longer than 10 µs, allowing a user to reset the circuit manually.
What are the reset output logic levels for ADM811 and ADM812?
ADM811 provides an active‑low reset output, while ADM812 provides an active‑high reset output.
What is the typical supply voltage range for the ADM811/ADM812?
The devices operate from 1.0 V up to 5.5 V supply voltage.
How long does the reset output stay active after power‑up?
The reset output remains active for about 140 ms (ADM811) or 240 ms (ADM812) after Vcc rises above the threshold.
