TF Semi completes spin-off from TSI Semiconductors, focusing on high-voltage power management including eGaN drivers
TF Semiconductor Solutions Inc of Roseville, CA, USA has completed its spin-off as an independent company after being the Products Division of TSI Semiconductors Inc (formerly Telefunken Semiconductors America), a specialty analog and mixed‐signal foundry with ISO, Automotive and Industrial Class Certifications. TF Semi is partnering with TSI Semiconductors Inc and its parent company Telefunken Semiconductor GmbH & Co KG of Heilbronn, Germany.
With design centers in Torrance, CA and Dover, NH, USA, TF Semi is capitalizing on many years of investment in product, IP research & development work from its original high-voltage integrated circuit (HVIC) efforts at Telefunken.
TF Semi is focusing on designing and manufacturing devices for the high-voltage power management market - where its HVIC devices have already won designs with motor and power supply manufacturers – as well as LED drivers, LVDS interface devices, and JTAG system testing solutions. In particular, as well as high-side & low-side drivers, half-bridge drivers and 3-phase drivers, the portfolio includes what is claimed to be the industry’s first 200V enhancement-mode gallium nitride (eGaN) driver, the TFG1200. TF Semi also offers a Specialty Products portfolio with devices targeting the LVDS interface, JTAG system test and power management for high-reliability applications.
The new company is led by Roger Lee, who over the past 25+ years has held senior executive management positions with Micron, SMIC, Founder Microelectronics. Most recently he was chief operating officer and interim president & CEO at TSI Semiconductors, where he continues to serve on the board of directors. “This is a great opportunity to capture a share of the fast-growing international green-power market,” says Lee. “TSI Semiconductor Solutions, as a fabless semiconductor company, is well positioned to participate in the fast-growing HV power management and driver IC market.”
TF Semi has sales and customer service offices in San Jose, CA, Sacramento, CA, Torrance, CA and Dover, NH, USA, in Taipei in Taiwan, and in Shenzhen and Beijing in China. The firm distributes its products through a network of global and regional distributors.
