SBS 1.1-COMPLIANT GAS GAUGE ENABLED WITH IMPEDANCE TRACK™

TECHNOLOGY FOR USE WITH THE bq29330

FEATURES

APPLICATIONS

•

Notebook PCs

Medical and Test Equipment

Portable Instrumentation

•

Next Generation Patented Impedance Track™

Technology accurately Measures Available

Charge in Li-Ion and Li-Polymer Batteries

•

Better than 1% Error Over Lifetime of the

Battery

DESCRIPTION

Instant Accuracy – No Learning Cycle

Required

The bq20z70 SBS-compliant gas gauge IC,

incorporating

patented

Impedance

Track™

technology, is designed for battery-pack or in-system

installation. The bq20z70 measures and maintains

an accurate record of available charge in Li-ion or

Supports the Smart Battery Specification SBS

V1.1

Powerful 8-Bit RISC CPU With Ultra-Low

Power Modes

Li-polymer

batteries

using

its

integrated

high-performance analog peripherals. The bq20z70

monitors capacity change, battery impedance,

open-circuit voltage, 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 bq29330 analog

front-end (AFE) protection IC to maximize

functionality and safety, and minimize component

count and cost in smart battery circuits.

Works With the TI bq29330 Analog Front-End

(AFE) Protection IC to Provide Complete Pack

Electronics Solution

•

Full Array of Programmable Protection

Features

–

Voltage, Current and Temperature

•

Fully Integrated High Accurate Clock

Flexible Configuration for 2 to 4 Series Li-Ion

and Li-Polymer Cells

The Impedance Track technology continuously

analyzes the battery impedance, resulting in superior

gas-gauging accuracy. This enables remaining

capacity to be calculated with discharge rate,

temperature, and cell aging all accounted for during

each stage of every cycle.

•

Integrated Field Programmable FLASH

Memory Eliminates the Need for External

Configuration Memory

•

Smart Battery Charger Control Feature

Two 16-Bit Delta-Sigma Converter
