3 Description
The bq20z655-R1 SBS-compliant gas gauge and protection IC, incorporating patented Impedance TrackTM technology, is a single IC solution 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 bq20z655-R1 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, the bq20z655-R1 maximizes functionality and safety while minimizing external component count, cost, and size in smart battery circuits.
The implemented Impedance TrackTM 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.
