3 Description
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 7-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.
