BQ20Z60-R1中文资料采用 Impedance Track™ 技术且符合 SBS 1.1 标准的电量监测计数据手册TI规格书

描述 Description

The bq20z60-R1 SBS-compliant gas gauge and protection IC, incorporating patented Impedance Track™ technology, is designed for battery-pack or in-system installation. The bq20z60-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 bq20z60-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. It is designed to work with the bq29330 analog front-end (AFE) protection IC to maximize functionality and safety, while minimizing external component count and cost in smart battery circuits.

The Impedance Track™ technology continuously analyzes the battery impedance, resulting in superior gas-gauging accuracy. This enables the remaining capacity to be calculated with discharge rate, temperature, and cell aging, which are all accounted for during each stage of every cycle with high accuracy.
