GENERAL DESCRIPTION
The ADM811/ADM812 is a reliable voltage monitoring device
suitable for use in most voltage monitoring applications. The
ADM811/ADM812 is designed to monitor six 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 2.5 V, 3 V, 3.3 V, and 5 V supply
voltage levels.
Included in this circuit is a debounced manual reset input.
Reset can be activated using an electrical switch (or an input
from another digital device) or by a degradation of the supply
voltage. The manual reset function is very useful, especially if
the circuit in which the ADM811/ADM812 is operating enters
into a state that can only be detected by the user. Allowing the
user to reset a system manually can reduce the damage or
danger that could otherwise be caused by an out-of-control or
locked system.
