Part Number : BQ20Z65-R1
Function : SBS 1.1-COMPLIANT GAS GAUGE AND PROTECTION ENABLED WITH IMPEDANCE TRACK
Manufacturers : Texas Instruments
The bq20z65-R1 SBS-compliant gas gauge and protection IC, incorporating patented Impedance Track technology, is a single IC solution designed for battery-pack or in-system installation.
The bq20z65-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 bq20z65-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 bq20z65-R1 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. 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.
