DescriptionThe BQ40Z50RSMR-R2 device, incorporatingpatented 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 andLi-Polymer battery packs.
Using its integrated high-performance analog peripherals, the BQ40Z50RSMR-R2 device measures and maintains an accurate record of availablecapacity, voltage, current, temperature, and other critical parameters in Li-Ion or Li-Polymerbatteries, and reports this information to the system host controller over an SMBus v1.1 compatibleinterface.
The BQ40Z50RSMR-R2 device supports TURBO Mode 2.0 by providingthe available max power and max current to the host system. The device also supports Battery TripPoint to send a BTP interrupt signal to the host system at the preset state of charge thresholds.
The BQ40Z50RSMR-R2 provides software-based 1st- and 2nd-levelsafety protection against overvoltage, undervoltage, overcurrent, short-circuit current, overload,and overtemperature conditions, as well as other pack- and cell-related faults.
SHA-1 authentication, with secure memory for authentication keys, enables identificationof genuine battery packs.
The compact 32-lead QFN package minimizes solution cost and size for smart batterieswhile providing maximum functionality and safety for battery gauging applications.
