GENERAL DESCRIPTION
The ADM811/ADM812 are reliable voltage monitoring
devices which are suitable for use in most voltage
monitoring applications.
The ADM811/ADM812 is designed to monitor 5 different
voltages, each allowing for a 5% or 10% degradation of
standard PSU voltages. These voltages have been carefully
selected for the effective monitoring of +3V, +3.3V and
+5V supply voltage levels.
Included in this circuit is a debounced Manual Reset input.
Reset will be activated with an ordinary mechanical switch
(or an input from another digital device) or a degredation of
the supply voltage. The Manual Reset function is very
useful especially if the circuit in which the ADM811/
ADM812 is operating in, 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 danger that could be
otherwise be caused by an out of control or locked-up
system.
