Newly released 48V integrated hot-swapable electronic fuses with power path protection simplify data center design and help designers reach power levels above 6kW.

The new integrated Gallium nitride (GaN) power stage combines Texas Instruments' GaN and high-performance gate drivers with advanced protection features in an industry-standard transient-shaped Toll-less package.

Shanghai, China (April 9, 2025) - Texas Instruments (TI) (NASDAQ: TXN) today introduced new power management chips to meet the rapidly growing power needs of modern data centers. With the increasing adoption of high-performance computing and artificial intelligence (AI), data centers demand higher power density and more efficient solutions. Texas Instruments' new TPS1685 is a 48-V integrated hot-swappable electronic fuse with power path protection that helps customers meet their data center hardware and processing needs. To simplify data center design, Texas Instruments also introduced a new family of integrated GaN power stages in the industry-standard TOLL package, the LMG3650R035, LMG3650R025 and LMG3650R070.

"With the increasing demand for energy in data centers, the global digital infrastructure is powering with smarter and more efficient semiconductors," said Robert Taylor, general manager, Industrial Power Design Services, Texas Instruments. "Advanced chips drive the computing power of artificial intelligence, and analog semiconductors are key to improving energy efficiency. Our innovative power management technology enables data centers to reduce their environmental impact while helping us meet the growing demands of the digital world."

Power levels above 6kW are achieved through intelligent system protection

As power demand surges, data center designers are turning to 48V power architectures to improve efficiency and scalability to better support components such as cpus, graphics processing units, and AI hardware accelerators. Texas Instruments' 48V stackable integrated hot-swappable electronic fuses with power path protection enable designers to meet high-power (>6kW) processing needs with a scalable device that simplifies design and reduces solution size by half compared to existing hot-swappable controllers on the market.

Texas Instruments' GaN power stages in industry-standard packages achieve greater efficiency

In addition, Texas Instruments introduced a new family of integrated GaN power stages. The LMG3650R035, LMG3650R025, and LMG3650R070 take advantage of TI Gans in industry-standard TOLL packages, allowing designers to take advantage of the efficiency of TI Gans without the need for costly and time-consuming redesigns.

The new power stage integrates a high-performance gate driver with a 650V GaN field-effect transistor (FET), achieving both high efficiency (>98%) and high power density (>100W/in3). These devices also incorporate advanced protection features, including overcurrent protection, short circuit protection, and overtemperature protection. This is particularly important for AC/DC applications such as server power, where designers are challenged to deliver more power in a smaller space.
