FEATURES

Provides Accurate Measurement of Available

Charge in Li-Ion and Li-Polymer Batteries

38-Pin TSSOP (DBT)

Supports the Smart Battery Specification

(SBS) V1.1

APPLICATIONS

Integrated Time Base Removes Need for

External Crystal

Notebook PCs

Medical and Test Equipment

Portable Instrumentation

Works With the TI bq29311 Analog Front-End

(AFE) Protection IC to Provide Complete Pack

Electronics for 10.8-V or 14.4-V Battery Packs

With Few External Components

DESCRIPTION

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

Uses 16-Bit Delta Sigma Converter for

Accurate Voltage and Temperature

Measurements

Programmable Cell Modeling for Maximum

Battery Fuel Gauge Accuracy
