The BQ40Z80 device, 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 2-series up to 6-series cell li-ion and li-polymer battery packs.

Using its integrated high-performance analog peripherals, the BQ40Z80 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.

Elliptic Curve Cryptography (ECC) or SHA-1 authentication with secure memory for authentication keys enables identification of genuine battery packs.

The BQ40Z80 device supports TURBO Mode 2.0/Intel Dynamic Battery Power Technology (DBPTv2) by providing the available max power and max current to the host system. The device has eight multifunction pins that can be configured as thermal inputs, ADC inputs, general purpose input/output (GPIO) pins, a presence pin, LED functions, display button input, or other functions. Status and flag registers are mappable to the GPIOs and used as interrupts to the host processor.
