NXP 800V Silicon Carbide (SiC) based Traction
Inverter Reference Design for EVs

The latest NXP 800V traction inverter reference design supports automotive EV applications and is aligned with the growing adoption of 800 V silicon carbide (SiC)–based inverter architectures. It has the latest generation of NXP MCU, gate drivers, Software packages and other high performance electrification devices.

Additionally, this is a production-ready platform for EV applications. It combines the best of hardware and software stack with architecture supporting up to ASIL D. This enables OEMs and Tier-1s to reduce integration effort, lower certification risk, and accelerate the implementation of next-generation 800V SiC traction inverters.
