1300 Henley Court Pullman, WA 99163 509.334.6306 www.digilentinc.com 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. 2 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.
