[{"type":"text","content":" DALLAS, May 1, 2019 /PRNewswire/ -- Texas Instruments (TI) (NASDAQ: TXN) today introduced fully tested reference designs for battery management and traction inverter systems, along with new analog circuits with advanced monitoring and protection features to help reduce carbon dioxide emissions and enable hybrid electric vehicles and electric vehicles (HEV/EVs) to drive farther and longer.\n\n \nSpeed time to market while achieving more accurate battery monitoring \nScalable across six to 96-series cell supervision circuits, TI's new battery management system (BMS) reference design features the advanced BQ79606A-Q1 precision battery monitor and balancer. Engineers can get their automotive designs to market quickly using the reference design, which implements the battery monitor in a daisy chain configuration to create a highly accurate and reliable system design for three- to 378-series, 12-V up to 1.5 kV lithium-ion battery packs. \nThe highly integrated BQ79606A-Q1 accurately monitors temperature and voltage levels and helps maximize battery life and time on the road. Additionally, the BQ79606A-Q1 battery monitor features safe-state communication that helps system designers meet requirements up to Automotive Safety Integrity Level D (ASIL D), which is the highest functional safety goal defined by the ISO 26262 road vehicles standard.\nReliable thermal management across the traction inverter system\nWith so many kilowatts of power filtering through an electric vehicle's traction inverter and batteries, high temperatures could potentially damage expensive and sensitive powertrain elements. Excellent thermal management of the system is crucial to vehicle performance, as well as protecting drivers and passengers. \nTo protect powertrain systems such as a 48-V starter generator from overheating, TI introduced the TMP235-Q1 precision analog output temperature sensors. This low-power, low-quiescent-current (9-µA) device provides high accuracy (±0.5°C typical and ±2.5°C maximum accuracy across the full operating temperature from -40°C to 150°C) to help traction inverter systems react to temperature surges and apply appropriate thermal management techniques. \nAdvanced protection without sacrificing space in traction inverter systems \nThe TMP235-Q1 temperature sensing device joins the recently released UCC21710-Q1 and UCC21732-Q1 gate...
