Texas Instruments announced a long-term collaboration with Delta Electronics, a global power and energy management manufacturer, to create next-generation electric vehicle (EV) onboard charging and power solutions. This work will leverage both companies’ research and development capabilities in power management and power delivery in a joint innovation laboratory in Pingzhen, Taiwan. Together, TI and Delta aim to optimize power density, performance and size to accelerate the realization of safer, faster-charging and more affordable EVs.
“The transition to electric vehicles is key to helping achieve a more sustainable future, and through years of collaboration with Delta Electronics, we have a solid foundation to build upon,” said Amichai Ron, senior vice president for Embedded Processing at TI. “Together with Delta, we will use TI semiconductors to develop EV power systems like onboard chargers and DC/DC converters that are smaller, more efficient and more reliable, increasing vehicle driving range and encouraging more widespread adoption of electric vehicles.”
“Delta has been developing high-efficiency automotive power products, systems and solutions since 2008 to help reduce transportation-related carbon emissions,” said James Tang, executive vice president of Mobility and head of the Electric Vehicle Solutions business group at Delta Electronics.
“Through the establishment of this joint innovation laboratory with TI, Delta intends to leverage TI’s abundant experience and advanced technology in digital control and GaN to enhance the power density and performance of our EV power systems. With more leading-edge product development and design capabilities, we aim to achieve closer technology exchange and collaboration to accelerate product development and improve product safety and quality. We look forward to furthering our technology leadership and creating a win-win situation in the rapidly developing electric vehicle market.”
Three phases of development for next-generation automotive power solutions
- Phase one for the collaboration focuses on Delta’s development of a lighter-weight, cost-effective 11kW onboard charger, using TI’s latest C2000™ real-time microcontrollers (MCUs) and TI’s proprietary active electromagnetic interference (EMI) filter products. The companies are working together using TI’s products to reduce the charger’s size by 30% while achieving up to 95% power conversion efficiency.
- In phase two, TI and Delta will leverage the latest C2000 real-time MCUs for automotive applications to enable automakers to achieve automotive safety integrity levels (ASILs) up to ASIL D, which represents the strictest automotive safety requirements. Highly integrated automotive isolated gate drivers will further enhance the power density of onboard chargers, while also minimizing overall solution size.
- In phase three, the two companies will collaborate to develop the next generation of automotive power solutions, capitalizing on TI’s more than 10 years of experience in developing and manufacturing products with gallium nitride (GaN) technology.
“The rapid growth of electronics in automotive applications has enabled more feature-rich, efficient and safer vehicles. However, technical challenges remain,” said Luke Lee, president of Taiwan, Japan, Korea and South Asia, Texas Instruments. “Having been in Taiwan for 55 years, coupled with decades of experience in automotive power management, TI has built a strong connection with the local automotive industry. Establishing this collaboration and joint innovation laboratory with Delta is just one more way TI is driving vehicle electrification forward.”

“onsemi’s decision to expand in Czechia is a clear confirmation of our country’s attractiveness for foreign investment and will bring significant momentum for the development of our economy,” said Mr. Jozef Síkela, Minister of Industry and Trade of the Czech Republic. “This investment not only strengthens our position in the semiconductor field but can also contribute to the development of the automotive industry and help us with its adaptation to the rise of electromobility.”
onsemi’s plan to expand SiC manufacturing with a multi-year brownfield investment of up to $2 billion (44 billion CZK) is part of the company’s previously disclosed long-term capital expenditure target. This investment would build on the company’s current operations in the Czech Republic, which include silicon crystal growth, silicon and silicon carbide wafer manufacturing (polished and EPI) and a silicon wafer fab. Today, the site can produce more than three million wafers annually, including more than one billion power devices. Upon completion, the operation would contribute annually more than $270 million USD (6 billion CZK) to the country’s GDP.
Pending all final regulatory and incentive approvals, including the investment incentive approval by the government of the Czech Republic and its notification to the European Commission, this would be one of the largest private sector investments in the Czech Republic’s history and would further contribute to the prosperity and economic dynamism of the Zlín region. onsemi is one of the first companies to invest in advanced semiconductor manufacturing in the Central European region.
With this investment, the company would contribute to the strategic positioning of the region within the EU’s semiconductor value chain and demonstrate that all EU countries can benefit from the European Chips Act. The announcement also reflects onsemi’s strategic alignment with the overarching goals of the European Chips Act of increasing market share and technological advancement to strengthen the resilience of the EU’s semiconductor supply chains in times of ever-growing demand.
Silicon carbide is a critical material for high-power, high-temperature applications, and is extremely difficult to produce. onsemi is one of the only companies in the world with the ability to manufacture SiC-based semiconductors from crystal growth to advanced packaging solutions. By expanding its production facilities in the Czech Republic, onsemi would be faster to provide supply assurance for customers, strengthening its leadership in intelligent power solutions. This integration would also enable onsemi to leverage its latest advancements in research and development (R&D) to maximize manufacturing and production efficiency.

ROHM has developed four models as part of the TRCDRIVE pack™ series with 2-in-1 SiC molded modules (two of 750V-rated: BSTxxxD08P4A1x4, two of 1,200V-rated: BSTxxxD12P4A1x1) optimized for xEV (electric vehicles) traction inverters. TRCDRIVE pack™ supports up to 300kW and features high power density and a unique terminal configuration – help solving the key challenges of traction inverters in terms of miniaturization, higher efficiency, and fewer person-hours.
As the electrification of cars rapidly advances towards achieving a decarbonized society, the development of electric powertrain systems that are more efficient, compact, and lightweight is currently progressing. However, for SiC power devices that are attracting attention as key components, achieving low loss in a small size has been a difficult challenge. ROHM solves these issues inside powertrains with its TRCDRIVE pack™.
A trademark brand for ROHM SiC molded type modules developed specifically for traction inverter drive applications, TRCDRIVE pack™ reduces size by utilizing a unique structure that maximizes heat dissipation area. On top, ROHM’s 4th Generation SiC MOSFETs with low ON resistance are built in – resulting in an industry-leading power density 1.5 times higher than that of general SiC molded modules while greatly contributing to the miniaturization of inverters for xEVs.
The modules are also equipped with control signal terminals using press fit pins enabling easy connection by simply pushing the gate driver board from the top, reducing installation time considerably. In addition, low inductance (5.7nH) is achieved by maximizing the current path and utilizing a two-layer bus-bar structure for the main wiring, contributing to lower losses during switching.
TRCDRIVE pack™ is scheduled to be launched by March 2025 with a lineup of 12 models in different package sizes (Small / Large) and mounting patterns (TIM: heat dissipation sheet / Ag sinter). In addition, ROHM is developing a 6-in-1 product with built-in heat sink that is expected to facilitate rapid traction inverter design and model rollout tailored to a variety of design specifications.
