PmodPMON1™ Reference Manual
Revised May 26, 2016
This manual applies to the PmodPMON1 rev. B
Overview
The PmodPMON1 employs the Analog Devices® AD5112 and ADM1191 to create a system power monitor.
Features include:
Monitor current draw less than 1.058 A
Wide range of configurable alert conditions
Monitor voltages from 3.16 V to 26 V
Configurable device address for up to nine
modules in a single system
Small PCB size for flexible designs 1.2“ × 0.8”
(2.8 cm × 2.0 cm)
2×4-pin connector with I2C interface
Follows Digilent Pmod Interface
Specification
The PmodPMON1.
1
Functional Description
Customers can configure the PMON1 to a wide range of possible alert conditions from the ADM1191 by using the
configurable AD5112 potentiometer. The AD5112 upper potentiometer connection ties to DVDD through a filtering
ferrite bead and the lower connection connects to GND. (See Table 1 for Connector Descriptions.) The wiper
directly connects to the SETV pin on the ADM1191 to allow for the wide range of alert conditions. If an alert
condition occurs, LD1 on the PMON1 will illuminate and the alert pin will go to a logic low state.

Using Multiple PmodPMON1s
In order to use multiple PMON1’s on a single I2C bus, each individual PMON1 will need to be connected; and the
desired potentiometer value programmed into the EEPROM on the AD5112. Any stored value will become the
default starting value for the potentiometer. The alert functionality available on the ADM1191 will not function
properly without programming each individual device. (See Table 2 for jumper descriptions.)
