Description
The bq2085 is an SBS-compliant gas gauge IC designed for use with Li-ion and Li-polymer batteries. It accurately measures available charge, monitors critical battery parameters, and communicates with the host controller via a serial bus. The bq2085 works in conjunction with the bq29311 AFE protection IC to provide complete pack electronics for 10.8-V or 14.4-V battery packs.
Features
SBS-compliant gas gauge IC
Accurate measurement of available charge
Supports SBS V1.1
Integrated time base eliminates need for external crystal
Works with bq29311 AFE protection IC
Powerful low-power RISC CPU core
Integrated FLASH memory eliminates need for external EEPROM
High-resolution 16-bit integrating converter
16-bit delta sigma converter for accurate voltage and temperature measurements
Programmable cell modeling for maximum accuracy
Drives 3-, 4-, or 5-segment LED display
Applications
Notebook PCs
Medical and test equipment
Portable instrumentation
