Overview
The BQ40Z50-R2 device employs the patented Impedance Track™ technology. It is a fully integrated, single-chip, battery pack-based solution that offers various features such as charge monitoring, protection, and authentication for 1-cell, 2-cell, 3-cell, and 4-cell series-connected lithium-ion and lithium-polymer battery packs. The BQ40Z50-R2 device utilizes its integrated high-performance analog peripherals to measure the available capacity, voltage, current, temperature, and other key parameters of lithium-ion or lithium-polymer batteries, maintains accurate data records, and reports this information to the system host controller via an SMBus v1.1 compatible interface. The BQ40Z50-R2 device supports TURBO Mode 2.0 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 preset state of charge thresholds. The BQ40Z50-R2 provides software-based 1st- and 2nd-level safety 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 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.
