Description for the BQ40Z50-R1
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.
The bq40z50-R1 provides software-based 1st- and 2nd-level safety protection against over voltage, under voltage, overcurrent, short-circuit current, overload, and over temperature conditions, as well as other pack- and cell-related faults.
SHA-1 authentication, with secure memory for authentication keys, enables identification of genuine battery packs.
The compact 32-lead QFN package minimizes solution cost and size for smart batteries while providing maximum functionality and safety for battery gauging applications.
