BQ20Z90-V150 符合 SBS v1.1 的电量监测计，与 bq29330 一起使用

BQ20Z90-V150 描述

The bq20z90 SBS-compliant gas gauge IC, incorporating patented Impedance TrackTM technology, is designed for battery-pack or in-system installation. The bq20z90 measures and maintains an accurate record of available charge in Li-ion or Li-polymer batteries using its integrated high-performance analog peripherals. The bq20z90 monitors capacity change, battery impedance, open-circuit voltage, and other critical parameters of the battery pack, and 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, and minimize component count and cost in smart battery circuits. The Impedance Track technology continuously analyzes the battery impedance, resulting in superior gas-gauging accuracy
