onsemi’s EliteSiC technology to be used in BMW’s EV drivetrains
Power semiconductor IC supplier onsemi of Phoenix, AZ, USA has announced a long-term supply agreement (LTSA) for its EliteSiC technology to be used by German premium car manufacturer BMW AG in its electric drivetrains for 400V DC bus. onsemi’s latest EliteSiC 750V M3 die is used in a full-bridge power module delivering several hundred kWs of power.
onsemi says that the companies’ strategic collaboration during the development and integration of the electric drivetrain enabled it 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, the firm adds.
“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,” says Asif Jakwani, senior VP & general manager, Advanced Power Division, Power Solutions Group, onsemi. “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.”
