3 Description

The

bq40z50-R2

device,

incorporating

patented

Impedance Track™ technology, is a fully integrated,

single-chip, pack-based solution that provides a rich

array of features for gas gauging, protection, and

authentication for 1-series, 2-series, 3-series, and 4-

series cell Li-Ion and Li-Polymer battery packs.

Using

its

integrated

high-performance

analog

peripherals, the bq40z50-R2 device measures and

maintains an accurate record of available capacity,

voltage,

current,

temperature,

and

other

critical

parameters in Li-Ion or Li-Polymer batteries, and

reports this information to the system host controller

over an SMBus v1.1 compatible interface.
