DESCRIPTION

The bq40z50 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.

Full Array of Programmable Protection

Features

Using its integrated high-performance analog

peripherals, the bq40z50 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.
