The bq20z75 SBS-compliant gas gauge and protection IC is a single IC solution designed for battery-pack or in-system installation. The bq20z75 measures and
maintains an accurate record of available charge in Li-ion or Li-polymer
batteries using its integrated high-performance analog peripherals, monitors capacity change, battery impedance, open-circuit voltage, and other
critical parameters of the battery pack as well and reports the information to the
system host controller over a serial-communication bus. Together with the integrated analog front-end (AFE) short-circuit and overload protection the bq20z75 maximizes functionality, safety and minimize external component count, cost and size in smart battery circuits.
The implemented Impedance Track™ gas gauging technology
continuously analyzes the battery impedance, resulting in superior gas-gauging
accuracy. This enables remaining capacity to be calculated with discharge rate,
temperature, and cell aging all accounted for during each stage of every cycle with high accuracy.
