SELECTING A FAULT TYPE
One of three fault types can be selected for each input:-
1. Under-voltage:- the input must fall below the programmed
threshold before a reset is generated
2. Over-voltage:- the input must rise above the programmed
threshold before a reset is generated
3. Out-of Window:- either an under-voltage or over-voltage fault
occurs.
The fault type is selected as shown in figure 35 below:-

SELECTING A VOLTAGE RANGE
The input pins of the ADM106x can monitor supplies over a
wide range- from 0.573V to 14.4V. Not all inputs can monitor
over this range- the GUI shows over what range a given input
can detect faults. In order to maximize the resolution of the
programmed threshold, each input has a number of ranges.
These ranges overlap to ensure that any threshold can be
programmed over the full range of an input. The following
table shows the different ranges available at the inputs. Note
that different devices may have a different number of each
input however the range for each type of input will be the same.
These ranges are important when monitoring a supply and an
appropriate range for that supply should be selected to provide
maximum resolution.

select an input to configure
INPUT RANGE
VX1-VX5 0.573V –1.375V
VP1 – VP4 0.573V – 1.375V
1.25V – 3.0V
2.5V – 6.0V
VH 2.5V – 6.0V
6.0V – 14.4V
Table 5 Input voltage ranges
VX1-VX5 are true High impedance inputs therefore a voltage
divider can be used to monitor voltages outside the specified
range. A voltage divider could also be employed at the VP
inputs however an input buffer would also be required.
The input range is selected in the software as shown in figure
