Know Your Safety Application Notes (Part 3): Pin FMEA

The article discusses the importance of an IC’s pin failure mode and effects analysis (FMEA) to meet functional-safety standards like IEC 61508 and ISO 13849. It highlights how Analog Devices’ safety application notes provide crucial information for technical safety analysis by system integrators designing safety-related systems. The article delves into what a pin FMEA entails, how it helps determine failure-rate distribution, and its significance in deriving the safe failure fraction (SFF) and probability of dangerous failure. It also touches on compliance with standards like IEC 61508 and ISO 13849, emphasizing the role of safety application notes in providing essential safety information for system integrators.
