3 Description
The bq40z50-R1 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-R1 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.
