BQ2084DBTR-V143 Description

Short technical summary and product information.

The BQ2084DBTR-V143 from Texas Instruments is an SBS v1.1 compliant gas gauge IC, specifically designed for use with the BQ29312A analog front-end protection IC. This component provides accurate measurement of available charge in Li-Ion and Li-Polymer batteries, supporting battery packs with 2 to 4 series cells.

 

Key features include an SMBus communication interface, a battery capacity range from 500 mAh to 15000 mAh, and an operating temperature range of -20°C to 85°C. The IC integrates a time base, removing the need for an external crystal, and works with the bq29312 AFE to create complete pack electronics for various battery pack voltages.

 

This gas gauge IC is housed in a 38-pin TSSOP package and is suitable for applications such as notebook PCs, medical and test equipment, and portable instrumentation. It utilizes a 16-bit Delta Sigma converter for accurate voltage and temperature measurements and a high-resolution 16-bit integrating converter for charge flow measurement.
