Texas Instruments High-Performance Analog Integrated Circuits (ICs) - Power Management (PMIC) - Battery Management BQ2084DBT-V140

The BQ2084DBT-V140 is a gas gauge integrated circuit designed for accurate monitoring of lithium-ion and lithium-polymer battery packs. It is compliant with the Smart Battery Specification (SBS) version 1.1 and utilizes a continuous sampling integrating converter for precise measurement of charge and discharge currents. The device features a 16-bit A-to-D converter for temperature and voltage monitoring, and it communicates data to the host controller via the System Management Bus (SMBus) protocol. This IC includes built-in flash memory for configuration storage, allowing for programmable cell modeling and automatic calibration of battery capacity during discharge cycles. It supports charge-control functions and provides LED drivers for visual indication of remaining battery capacity in increments of 20%, 25%, or 33%. The BQ2084DBT-V140 operates within a supply voltage range of 3V to 3.6V and is available in a 38-pin TSSOP package. It is suitable for applications in portable electronics, medical devices, and other battery-powered systems.
