As part of this, they have set up a joint laboratory in Pingzhen, Taiwan.

“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,” said TI’s president of Taiwan, Japan, Korea and South Asia. “Establishing this collaboration with Delta is just one more way TI is driving vehicle electrification forward.”

“Delta has been developing automotive power products since 2008,” said Delta head of electric vehicle (EV) business James Tang. “Through the establishment of this joint laboratory with TI, Delta intends to leverage TI’s experience and technology in digital control and GaN to enhance the power density and performance of our EV power systems.”

Three collaboration phases are planned:

• Development of a 11kW on-board charger, using TI’s C2000 MCUs and its active EMI (electromagnetic interference) filtering ICs. Up to 95% power conversion efficiency is one of the product targets.

• Achieve ASIL D (automotive safety integrity level D) readiness using C2000 MCUs. “Highly integrated automotive isolated gate drivers will further enhance the power density of onboard chargers,” added TI.

• Develop automotive power products using TI GaN components.
