Battery

Instant Accuracy – No Learning Cycle

Required

DESCRIPTION

The bq20z80 SBS-compliant gas gauge IC,

incorporating patented Impedance Track technology,

is designed for battery-pack or in-system installation.

The bq20z80 measures and maintains an accurate

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

batteries using its integrated high-performance

analog peripherals. The bq20z80 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 bq29312A analog front-end (AFE)

protection IC to maximize functionality and safety,

and minimize component count and cost in smart

battery circuits.

Supports the Smart Battery Specification SBS

V1.1

Works With the TI bq29312A Analog

Front-End (AFE) Protection IC to Provide

Complete Pack Electronics Solution

•

Full Array of Programmable Voltage, Current,

and Temperature Protection Features

Integrated Time Base Removes Need for

External Crystal with Optional Crystal Input

Electronics for 7.2-V, 10.8-V or 14.4-V Battery

Packs With Few External Components

Based on a Powerful Low-Power RISC CPU

Core With High-Performance Peripherals

Integrated Field Programmable FLASH

Memory Eliminates the Need for External

Configuration Memory

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.
