SBS 1.1-COMPLIANT GAS GAUGE AND PROTECTION-ENABLED IC

WITH IMPEDANCE TRACK™

FEATURES

DESCRIPTION

•

Next Generation Patented Impedance Track™

Technology accurately Measures Available

Charge in Li-Ion and Li-Polymer Batteries

The bq20z75 SBS-compliant gas gauge and

protection IC is a single IC solution designed for

battery-pack or in-system installation. The bq20z75

measures and maintains an accurate record of

available charge in Li-ion or Li-polymer batteries

using its integrated high-performance analog

peripherals, monitors capacity change, battery

impedance, open-circuit voltage, and other critical

parameters of the battery pack as well and 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 bq20z75 maximizes

functionality, safety and minimize external component

count, cost and size in smart battery circuits.

–

Better than 1% Error Over Lifetime of the

Battery

–

Instant Accuracy – No Learning Cycle

Required

•

Supports the Smart Battery Specification

SBS V1.1

Flexible Configuration for 2 to 4 Series Li-Ion

and Li-Polymer Cells

Powerful 8-Bit RISC CPU With Ultra-Low

Power Modes

Full Array of Programmable Protection

Features

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.
