Fault Management Architecture
Jul 11th 2013
I recently had some enquiries into using PMBus communication to manage faults vs. built-in fault management. The question was two fold: what is the impact of using PMBus to make fault-off decisions, and what can be done to build system wide fault logs?
Before I dig into these two uses of PMBus, let’s consider what is ...
Digital Point of Load Converters vs. Digital Managers
Sep 1st 2012
When should you use a Point of Load Converter (POL) with PMBus, and when should you use a Digital Manager with old school POLs? In this post I will provide some heuristics for making this choice.
So as to not mislead, my goal is modest: to provide enough intuition to make a first pass choice, that becomes an area to explore ...
Digital Power Supervision and Telemetry
Aug 21st 2012
What does a Digital Power device do between start-up and shutdown? Two core functions are supervision and telemetry. Supervision is a fast acting safety feature that prevents damage to the device and/or load. Telemetry is an ongoing quality management feature.
A recent advertisement in Bodo’s Power Systems listed the ...
