The BQ20Z655DBT-R1 is a SBS v1.1 compliant Gas Gauge with LED/LCD drive and Impedance Track? technology designed for battery-pack or in-system installation. The BQ20Z655-R1 measures and maintains an accurate record of available charge in Li-ion or Li-polymer batteries using its integrated high-performance analog peripherals. The gauge monitors capacity change, battery impedance, open-circuit voltage and other critical parameters of the battery pack which 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, it maximizes functionality and safety while minimizing 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.
