Input / OutputLow-side and high-side drivers with open-circuit and short-circuit detectionjeudi, 21 février 2008 | Stephane
According to Failure Mode Effects Analysis (FMEA), you may implement a circuitry in order to detect the failures on a digital output.
The following schematics allows to detect open-circuits and short-circuits on low-side and high-side drivers. The 'Control' and 'Status' wires are connected... + Full Story

These US Satellites from the National Oceanic and Atmospheric Administration (NOAA) are operating in the 137MHz and 1.7GHz bands. They fly on polar orbits at about 850km above the Earth's surface and their orbital period is about 100min.
These sateliites are transmitting continuously... + Full Story
Design rules, guidelines and toolsIntroduction to FMEAlundi, 17 mars 2008 | Stephane
FMEA is a way to check that any failure mode has been taken into account in the design. This step is essential in a product design. This analyse is reported in a FMEA document.
The Preliminary Risk Assessment is the first assessment done before re-designing a product.
