Texas Instruments today introduced new semiconductors designed to improve automotive safety and intelligence. The AWR2544 77GHz millimetre-wave radar sensor chip is the industry’s first for satellite radar architectures, enabling higher levels of autonomy by improving sensor fusion and decision-making in ADAS.

TI’s new software-programmable driver chips, the DRV3946-Q1 integrated contactor driver and DRV3901-Q1 integrated squib driver for pyro fuses, offer built-in diagnostics and support functional safety for battery management and powertrain systems. TI is demonstrating these new products at the 2024 Consumer Electronics Show (CES) underway from January 9-11 in Las Vegas.

“Semiconductor innovations like the ones we’re showcasing this year at CES are helping automotive systems continue to evolve and contribute to a safer driver experience,” said Fern Yoon, director of Automotive Systems at Texas Instruments. “From more advanced driver assistance systems to smarter electric vehicle powertrain systems, TI is working alongside automakers to reimagine how reliable and intelligent technology can enable safer vehicles.”

 Increased radar performance for smarter ADAS decision-making

Many automakers are adding more sensors around the car to improve vehicle safety and autonomy. TI’s AWR2544 single-chip radar sensor is the industry’s first designed for satellite architectures. In satellite architectures, radar sensors output semi-processed data to a central processor for ADAS decision-making using sensor fusion algorithms, taking advantage of the 360-degree sensor coverage to achieve higher levels of vehicle safety.

The AWR2544 single-chip radar sensor is also the industry’s first with launch-on-package (LOP) technology. LOP technology helps reduce the size of the sensor by as much as 30% by mounting a 3D waveguide antenna on the opposite side of the printed circuit board. LOP technology also enables sensor ranges to extend beyond 200m with a single chip. In satellite architectures, these features enable automakers to increase ADAS intelligence for higher vehicle autonomy levels to make smarter decisions from farther away.

The AWR2544 is the latest in TI’s radar sensor portfolio, which supports a wide range of ADAS applications and architectures with sensors developed for corner, front, imaging, side and rear radar systems.
