Theory of Operation
Analog Monitor Inputs
The ispPAC-POWR1014/A provides 10 independently programmable voltage monitor input circuits as shown in
Figure 2-7. Two individually programmable trip-point comparators are connected to an analog monitoring input.
Each comparator reference has 370 programmable trip points over the range of 0.672V to 5.867V. Additionally, a
75mV ‘zero-detect’ threshold is selectable which allows the voltage monitors to determine if a monitored signal has
dropped to ground level. This feature is especially useful for determining if a power supply’s output has decayed to
a substantially inactive condition after it has been switched off.
