Automotive precision electronic fuse reference design

TIDA-00795

 
Overview

Fuses are used in many products to protect against possible damage caused by current surges and overcurrents. Traditional fuses used in the automotive space have lower accuracy and longer response times. The TIDA-00795 Automotive Precision Electronic Fuse Reference Design is an alternative to traditional fuses that is more accurate and offers capabilities not found in traditional fuses. This electronic fuse reference design can be used as a building block for implementing a multi-channel electronic fuse box. It can also be used in body control modules (BCM) and electronic control units (ECU).
