onsemi to supply EliteSiC technology to BMW for 400V DC bus in next-gen EVs

onsemi, a provider of intelligent power and sensing technologies, announced a long-term supply agreement (LTSA) with BMW AG for onsemi’s EliteSiC technology in BMW’s electric drivetrains for 400 V DC Bus. onsemi’s latest EliteSiC 750 V M3 die is used in a full bridge power module delivering several hundred kilowatts of power.

The companies’ strategic collaboration during the development and integration of the electric drivetrain enabled onsemi to provide differentiated and application-specific die solutions, including optimized size and layout as well as high performance and reliability.

Enhanced electrical and mechanical characteristics produce high efficiency and lower overall losses while delivering the highest system-level performance.

With maximum range being a primary consideration for purchasing an EV, onsemi’s system approach for optimized performance across all of BMW’s electric vehicles provides a key competitive advantage. In addition, we are able to support the rapidly increasing demand for BMW’s premium EVs by continuously ramping all production steps of our robust, vertically integrated SiC supply chain.
