Note: This document applies to REV B of the board.
Overview
The PmodPMON1 employs the Analog
Devices® AD5112 and ADM1191 to create a
system power monitor.
Features include:
•
•
monitor current draws less than 1.058A
monitor voltages from 3.16V to 26V on
the J3 VIN pin
•
•
•
DVDD input ranges from 3V to 5.5V
standard I2C interface
configurable device address allows for
up to nine PMON1s in a single system
Device Configuration
Functional Description
For specific information related to device
configuration on the AD5112 and ADM1191,
please refer to the data sheets available at
www.analog.com
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.

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.)
