TI unveils automotive semiconductors at CES 2024: mmwave radar sensor chip and driver ICs
Date: 11/01/2024
Texas Instruments introduces industry's first 77GHz millimeter-wave radar sensor chip for satellite radar architectures, enhancing sensor fusion and decision-making in Automotive ADAS for higher autonomy levels and safer driver experience. TI announed this at CES 2024.
The new AWR2544 chip provides semi-processed data to centalized ADAS computer to decide using sensor fusion algorithms, taking advantage of the 360-degree sensor coverage. AWR2544 also feature another industry’s first by using launch-on-package (LOP) tech which 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. 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. AWR2544 extend sensor ranges beyond 200m, contributing to smarter ADAS decisions from farther away.
TI also launched the new software-programmable driver chips, a fully integrated contactor driver DRV3946-Q1 and a fully integrated squib driver DRV3901-Q1.
DRV3946-Q1 offers peak-and-hold current controller that helps automakers increase system power efficiency. The device also implements safety diagnostics to monitor the condition of the contactor.
DRV3901-Q1 supports intelligent pyro fuse disconnect system by using built-in circuitry to monitor the pyro fuse and provide diagnostic information to the system microcontroller. With this chip hybrid electric vehicle (HEV) and EV BMS designers can opt pyro fuse instead of traditional melting fuse systems to simpify their designs.
TI is demonstrating these innovations at CES 2024.
