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 the Lifetime of

the Battery

DESCRIPTION

•

Supports the Smart Battery Specification

SBS V1.1

The bq20z65-R1 SBS-compliant gas gauge and

protection IC, incorporating patented Impedance

Track™ technology, is a single IC solution designed

for battery-pack or in-system installation. The

bq20z65-R1 measures and maintains an accurate

record of available charge in Li-ion or Li-polymer

batteries using its integrated high-performance

analog peripherals. The bq20z65-R1 monitors

capacity change, battery impedance, open-circuit

voltage, and other critical parameters of the battery

pack which reports the information to the system host

controller over a serial-communication bus. Together

with the integrated analog front-end (AFE)

short-circuit and overload protection, the bq20z65-R1

maximizes functionality and safety while minimizing

external component count, cost, and size in smart

battery circuits.

Flexible Configuration for 2 to 4 Series Li-Ion

and Li-Polymer Cells

Powerful 8-Bit RISC CPU With Ultralow Power

Modes

Full Array of Programmable Protection

Features

–

Voltage, Current, and Temperature

•

Satisfies JEITA Guidelines

Added Flexibility to Handle More Complex

Charging Profiles

•

Lifetime Data Logging

Drives 3, 4, and 5 Segment LED Display for

Battery-Pack Conditions

The implemented Impedance Track™ gas gauging

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 with high accuracy.
