Onsemi is an American semiconductor company that was spun out of Motorola in 1999 and has since narrowed itself from a broad commodity chip supplier into a focused power and sensing business. Its silicon carbide and silicon power devices go into electric vehicle traction inverters, chargers and industrial drives, while its image sensors are used in automotive cameras and industrial vision, and it has deliberately exited lower-margin product lines to concentrate on these markets. Headquartered in Scottsdale, Arizona and listed on Nasdaq, it owns its own silicon carbide substrate manufacturing to secure supply.
