The BQ40Z50EVM-561 device, incorporating patented ImpedanceTrack technology, is a fully integrated, single-chip, pack-based solution that providesa 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 BQ40Z50EVM-561 device measures andmaintains an accurate record of available capacity, voltage, current, temperature, and othercritical parameters in Li-Ion or Li-Polymer batteries, and reports this information to the systemhost controller over an SMBus v1.1 compatible interface.

The BQ40Z50EVM-561 devicesupports 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 atthe pre-set state of charge thresholds.

The BQ40Z50provides software-based 1st- and 2nd-level safety protection against overvoltage, undervoltage,overcurrent, short-circuit current, overload, and overtemperature conditions, as well as otherpack- 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.
