DESCRIPTION

D
Based on a Powerful Low-Power RISC CPU  
Core With High-Performance Peripherals  
The bq2085−V1P3 SBS-compliant gas gauge IC for  
battery pack or in-system installation maintains an  
accurate record of available charge in Li-ion or Li-polymer  
batteries. The bq2085−V1P3 monitors capacity and other  
critical parameters of the battery pack and reports the  
information to the system host controller over a serial  
communication bus. It is designed to work with the  
bq29311 analog front-end (AFE) protection IC to maximize  
functionality and safety and minimize component count  
and cost in smart battery circuits. Using information from  
the bq2085−V1P3, the host controller can manage  
remaining battery power to extend the system run time as  
much as possible.  
Integrated Flash Memory Eliminates the Need  
for External Configuration EEPROM  
Measures Charge Flow Using a High  
Resolution 16-Bit Integrating Converter  
− Better Than 3-nVh of Resolution  
− Self-Calibrating  
− Offset Error Less Than 1 µV
