BQ40Z50RSMT-R1

BATT GAUGE/MANAGER, LI-ION/POL, VQFN-32.

The BQ40Z50RSMT-R1 is a Li-ion Battery Fuel (Gas) Gauge 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. This 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.
