Power system management design

Michael Jones- July 27, 2012

The focus of the blog will be power system design and integration of PMBus-controlled devices. It will be oriented to the analog engineer who may not be familiar with these devices, what problems they solve, or how to architect high-availability multi-rail systems.

The PMBus 1.3 specification addresses faster alert response, device discovery and system control by introducing Zone Reads and Zone Writes

02.08.2014

Previously I discussed the idea of Global Process Call as a method of getting prioritized data from every PMBus device within a system. The industry listened and responded with a request for getting data from a targeted subset of devices. A desire for data writes to all or some devices was also voiced. Read More...
