GENERAL DESCRIPTION
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
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 manually reset a system can reduce the damage or dan-
ger that could be otherwise caused by an out-of-control or
locked up system.
