Introduction

Functional Safety has become increasingly crucial for numerous industrial and automotive systems, not only across a variety of applications but also in achieving higher safety levels. In this application note, Microchip presents an evolutive path to implement advanced functional safety levels (SIL 3, ASIL D) while mitigating common challenges users may face. After reviewing the theory of operation, the principles are practically applied to an e-Fuse, a widely used application for protecting loads in various end markets.
