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 six different voltages, each allowing 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.
