About this document​

Scope and purpose​

As requirements from functional safety standards in automotive, industrial and other fields are a challenging subject, this document series intends to provide a first set of guidelines for users who are unfamiliar using Infineon products in a functional safety scope.

Intended audience​

This application note series is intended for all those evaluating Infineon products, including functional safety engineers on the customer side and application engineers. This includes designers of safety-related systems who:

  • Are new to functional safety

  • Want to know more about functional safety (also called “FuSa”) applications

  • Want to understand in principle how functional safety can be implemented with hardware support

  • Are looking for functional safety details that cannot be found in the user manual of the product

Structure of the document​

This document is a list of released application notes addressing various aspects of functional safety with Infineon products.

The series is divided into three main sections: theory, applications and software (SW) aspects.

Disclaimer​

Documents about application use cases are for training purposes only and are not to be taken as a blueprint for productive development.
