As 48 V electric passenger vehicles replace cars with 12 V electrical systems and internal combustion engines, Littelfuse innovates with solutions for EVs and improves electronics for traditional vehicles. We make battery terminal protectors, power distribution modules, camshaft position sensors, and full portfolios of OEM, custom, and aftermarket overvoltage and overcurrent protection devices.

Electrical systems in high-voltage EVs carry current at between 60 V and 1.5 kV. This demands high-performance circuit protection, and Littelfuse delivers. Our automotive fuses, TVS diodes, and thermal protectors help prevent damage to batteries, wiring harnesses, dc motors, and traction inverters. We also supply many solutions for power distribution, power conversion, and current switching.

Two- and 3-wheelers dominate roadways in much of the world. Whether used as utility, delivery, or passenger vehicles, these scooters, motorcycles, and vans require advanced electronic components. Littelfuse provides solutions for EVs and vehicles with internal combustion engines, including circuit protection devices, battery protectors, and solid-state relays for power management.
