TI's bq40z50-R2 devices use patented impedance tracking technology. It is a fully integrated single-chip packaging solution for 1-series, 2-series, 3-series and 4-lithium-ion battery series batteries, with rich gas metering, protection and certification functions, and lithium polymer battery packs.
& Nbsp; Using integrated high-performance analog peripherals, the device can measure and maintain the available capacity, lithium ion or lithium polymer in accurate records of batteries, voltage, current, temperature and other key parameters, and report this information to System host controller with SMBus v1.1 compatible interface.
& Nbsp; The device supports TURBO mode 2 by providing the maximum power and current available to the host system. The device also supports a battery trip point and sends a BTP interrupt signal to the host system at a preset charge threshold state.
& Nbsp; The device provides software-based first- and second-level safety protection against overvoltage, undervoltage, overcurrent, short-circuit current, overload and overheat conditions, and other package and battery failures.
& Nbsp; SHA-1 authentication with secure memory for authentication key can identify the real battery pack.
& Nbsp; The compact 32-pin QFN package maximizes the cost and size of the smart battery solution, while providing maximum functionality and safety for battery measurement applications.
