The BQ79631-Q1 from Texas Instruments is a high-accuracy UIR sensor designed for voltage, current, and insulation resistance monitoring in electric vehicle (EV) and hybrid vehicle (HV) battery management systems (BMS).
This device is qualified for automotive applications and AEC-Q100 certified, ensuring reliability in demanding environments with an operating temperature range of -40°C to +125°C. It supports functional safety applications, with systematic and hardware capabilities up to ASIL D, and provides documentation to aid ISO 26262 system design.
Key features include differential voltage measurements with integrated filtering for Pack+, Fuse, Link, and Charge nodes, integrated precision current measurement supporting low-side shunt resistors, and insulation resistance monitoring capability. It also offers 8 GPIO inputs for various functions like temperature sensing and SPI communication. The device simplifies system design with isolated differential daisy-chain communication, eliminating the need for a safety MCU and CAN transceivers in some configurations. It communicates via UART and SPI.
The BQ79631-Q1 is available in a 64-pin HTQFP package with a surface mount type. It is designed for applications in full electric, plug-in hybrid, and hybrid vehicles, providing critical data for battery pack monitoring and management.
