Hybrid Electric Vehicle (HEV)

Hybrid Electric Vehicles utilize a battery system that works in conjunction with an electric motor drive system to power the automobile. Silicon Labs’ multi-channel isolators, isolated gate drivers and isolated current sensors provide higher levels of integration when compared to traditional digital optocouplers and optocoupler plus gate driver solutions.
