Description

General part information

BQ40Z50-R1 Series

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.

The bq40z50-R1 device supports TURBO BOOST mode by providing the available max power and max current to the host system. The device also supports Battery Trip Point to send a BTP interrupt signal to the host system at the pre-set state of charge thresholds.
