Description

The power management bus (PMBus) is a variant

of the system management bus (SMBus) which is

targeted at digital management of power supplies.

Like SMBus, it is a relatively slow speed two wire

communications protocol based on I²C. The

PMBus protocol helps to establish the first truly

open communications standard for the digital

control of power systems facilitating the

programming, control and real-time monitoring of

compliant power conversion products.

The objective of this demonstration board is to

show to the user the features and capabilities of

PMBus using ST7 I2C peripheral, to support the

standard PMBus commands.

This demonstration board has ST72651AR6

Microcontroller (MCU) that has an I2C peripheral.

This microcontroller acts as the PMBus master.

This demonstration board works with PC GUI and

controls one or more PMBus compatible slaves

connected on the shared bus. Even though its

main purpose is to interface with ST PMBus

devices (PM881x), it could be used to interface

with other devices making use of the supported

set of command.
