Texas Instruments debuts new EV chips at CES

January 16, 2024

Texas Instruments introduced new semiconductors aimed at enhancing automotive safety and intelligence.

For EV powertrains, TI’s new driver chips, the DRV3946-Q1 and DRV3901-Q1, address the need for safer and more efficient control of high-voltage disconnect circuits in battery management systems (BMS) or other powertrain systems. Both drivers are International Organization for Standardization (ISO) 26262 functional safety-compliant and offer built-in diagnostics and protection to reduce automotive engineers’ development time.

The AWR2544 single-chip radar sensor is the first designed for satellite architectures, which allows radar sensors to output semi-processed data to a central processor for ADAS decision-making. This takes advantage of the 360-degree sensor coverage to achieve higher levels of vehicle safety. The AWR2544 also features launch-on-package (LOP) technology, which reduces the size of the sensor by up to 30% and extends sensor ranges beyond 200m with a single chip.

Preproduction quantities of the AWR2544, DRV3901-Q1 and DRV3946-Q1 and evaluation modules are now available for purchase on TI.com
