Jan. 9, 2024 -- Texas Instruments Incorporated (TI) (NASDAQ: TXN) today unveiled new semiconductors designed to improve automotive safety and intelligence.The AWR2544 77GHz millimeter-wave radar sensor chip, designed with a satellite radar architecture, enables a higher level of autonomy by improving sensor fusion and decision-making capabilities in advanced driver assistance systems (ADAS). higher levels of autonomy by enhancing sensor fusion and decision-making capabilities in advanced driver assistance systems (ADAS). TI's new driver chips, the DRV3946-Q1 integrated contactor driver and the DRV3901-Q1 integrated thermal fuse burst driver, are software programmable, provide built-in diagnostics and support functional safety for battery management systems and powertrain systems. TI will showcase these new products at the 2024 International CES.
Semiconductor innovations like the ones we're showcasing at CES this year are driving the evolution of automotive systems and helping to make the driving experience safer," said Fern Yoon, director of automotive systems at Texas Instruments (TI). From more advanced driver assistance systems to smarter electric vehicle powertrain systems, Texas Instruments is working with automakers to envision how reliable and intelligent technologies can enable safer vehicles." Many automakers are adding more sensors around their vehicles, aiming to improve their safety and autonomy. The Texas Instruments AWR2544 single-chip radar sensor is a sensor designed for satellite architecture. In a satellite architecture, the radar sensor uses sensor fusion algorithms to output partially processed data to a central processor for ADAS decision making, and utilizes 360-degree sensor coverage to achieve a higher level of vehicle safety. The AWR2544 single-chip radar sensor also utilizes Waveguide Interface Package (LOP) technology, which supports the installation of a 3D waveguide antenna on the other side of the printed circuit board, helping to reduce the size of the sensor by as much as 30%, and also supports the extension of the sensor range beyond 200m with a single chip. In satellite architectures, these features can help automakers improve ADAS intelligence to increase vehicle autonomy and enable more informed decision making at longer distances. The AWR2544 is a new addition to Texas Instruments' radar sensor portfolio, supporting a wide range of ADAS applications and architectures, with sensors for corner radar, front radar, imaging radar, side radar, and rear radar systems. systems. With the trend toward software-defined vehicles, designers are challenged to develop smarter, more advanced battery management systems (BMS). Texas Instruments has introduced two new highly integrated and software-programmable driver chips that enable safer and more efficient control of high-voltage disconnect circuits in the BMS or other powertrain systems. Both drivers are compliant with the International Organization for Standardization (ISO) 26262 functional safety standard and offer built-in diagnostics and protection features to reduce development time for automotive engineers. For BMS and other powertrain systems, the DRV3946-Q1 is a fully integrated contactor driver. The device includes a peak and hold current controller to help automakers improve system efficiency. The device is also capable of monitoring contactor status using safe diagnostic techniques. The Texas Instruments DRV3901-Q1 fully integrated burst driver enables an intelligent thermal fuse disconnect system by using built-in circuitry to monitor the thermal fuse and provide diagnostic information to the system microcontroller. This gives hybrid electric vehicle (HEV) and electric vehicle (EV) BMS designers the flexibility to use thermal fuses in place of traditional blown fuse systems, while minimizing design complexity.
