Highlights

This advanced single-chip radar sensor designed for satellite architecture extends vehicle sensing range to more than 200 meters and improves the accuracy of advanced driver assistance system (ADAS) decision-making.
The new driver chips enable safe and efficient control of power flow in battery management systems or other powertrain systems, and feature functional safety compliance and built-in diagnostics to reduce development time.

Texas Instruments Incorporated (TI) today introduced new semiconductor products designed to make automobiles safer and smarter . The AWR2544 77GHz millimeter wave radar sensor chip is designed with a satellite radar architecture to achieve a higher level of autonomy by improving sensor fusion and decision-making capabilities in advanced driver assistance systems (ADAS). Texas Instruments' new driver chips DRV3946-Q1 integrated contactor driver and DRV3901-Q1 integrated thermal fuse squib driver support software programming, provide built-in diagnostics and support functional safety for battery management systems and powertrains into a system. Texas Instruments will showcase these new products at the 2024 International Consumer Electronics Show (CES).

Fern Yoon, director of automotive systems at Texas Instruments (TI), said: "Semiconductor innovations like the ones we demonstrated at CES this year are driving the continuous development of automotive systems and helping to bring a safer driving experience. From more advanced driver assistance systems to Smarter electric vehicle powertrain systems, Texas Instruments is working with automakers to envision how to enable safer vehicles through reliable and intelligent technology."

Improve radar performance,

Enable smarter ADAS decisions

Many automakers are adding more sensors around their vehicles, aiming to increase vehicle safety and autonomy. The Texas Instruments AWR2544 single-chip radar sensor is a sensor designed specifically for satellite architecture. In satellite architecture, radar sensors use sensor fusion algorithms to output partially processed data to a central processor for ADAS decision-making, leveraging 360-degree sensor coverage to achieve higher levels of vehicle safety.

The AWR2544 single-chip radar sensor also uses waveguide interface package (LOP ) technology. LOP technology enables 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 up to 30%. LOP technology also enables sensor range to be extended to more than 200m with a single chip. In satellite architecture, these features can help automakers increase the level of ADAS intelligence to increase vehicle autonomy, enabling smarter decisions to be made at greater distances. The AWR2544 is a new addition to Texas Instruments' radar sensor portfolio that supports a variety of ADAS applications and architectures, including sensors for corner radar, front radar, imaging radar, side radar and rear radar systems.

With integrated functionality and security,

Making electric powertrain systems smarter

As the software-defined automotive trend develops, designers are faced with the challenge of developing smarter and more advanced battery management systems (BMS). Texas Instruments has launched two new driver chips that are highly integrated and support software programming, enabling safer and more efficient control of high-voltage disconnect circuits in BMS or other powertrain systems. Both drives comply 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.

The DRV3946-Q1 is a fully integrated contactor driver for BMS and other powertrain systems. This device includes a peak and hold current controller that helps automakers improve system energy efficiency. The device also uses safety diagnostics to monitor the status of the contactor.

Texas Instruments' DRV3901-Q1 fully integrated squib 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.
