Protect, Recover, Repeat: Inside a Smart Automotive eFuse (Download)
In the first part of this series, we explored how an electronic fuse (eFuse) assembled out of power switches and high-speed comparators can protect against common short conditions. In this second part, we examine what happens after the occurrence of a fault. We dive into the recovery dynamics of the design after a short-to-ground condition and how to add diagnostic capabilities to it. In addition, test results are presented that show how this approach to automotive circuit protection performs with actual hardware.
