The BQ2085DBT from Texas Instruments is an SBS-compliant gas gauge IC suitable for battery pack or in-system installation. It accurately maintains a record of available charge in Li-ion or Li-polymer batteries. The IC monitors capacity and other critical battery pack parameters, reporting this information to the system host controller over a serial communication bus (SMBus).
Key features include support for the Smart Battery Specification (SBS) V1.1, an integrated time base that eliminates the need for an external crystal, and compatibility with the TI bq29311 Analog Front-End (AFE) Protection IC. It is built on a low-power RISC CPU core with high-performance peripherals and integrated flash memory, removing the need for external configuration EEPROM.
The BQ2085DBT measures charge flow using a high-resolution 16-bit integrating converter with better than 3-nVh resolution and self-calibrating offset error less than 1 µV. It also utilizes a 16-bit Delta Sigma converter for accurate voltage and temperature measurements. Programmable cell modeling ensures maximum battery fuel gauge accuracy, and it can drive 3-, 4-, or 5-segment LED displays for remaining capacity indication.
This IC is housed in a 38-pin TSSOP package and operates within a temperature range of -20°C to 85°C. Its primary applications include notebook PCs, medical and test equipment, and portable instrumentation.
