Littelfuse In-Vehicle Communication Solutions

Littelfuse provides a wide portfolio of fuses, diode arrays, and suppressors suitable for in-vehicle communication applications. The automotive environments are divided into domain architecture and zonal architecture. The domain architecture controls and divides by function, and computation can be performed locally. Zonal architecture environments require a software-based approach, and a central computer is linked to sensors and devices through zonal gateways.
