BQ20Z95中文资料采用了 Impedance Track 的符合 SBS 1.1 的电量监测计数据手册TI规格书

描述 Description

The bq20z95 SBS-compliant gas gauge and protection IC is a single IC solution designed forbattery-pack or in-system installation. The bq20z95 measures and maintains an accurate record of available charge in Li-ion or Li-polymer batteries using its integrated high-performance analogperipherals, 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 bq20z95 maximizes functionality and safety while minimizing external component count, cost, and size in smart battery circuits.

The implemented Impedance Track TM 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.
