BQ2085-V1P3 符合 SBS 的电量监测计 IC,与 bq29311 一起使用

BQ2085-V1P3 描述

The bq2085-V1P3 SBS-compliant gas gauge IC for battery pack or in-system installation maintains an accurate record of available charge in Li-ion or Li-polymer batteries. The bq2085-V1P3 monitors capacity 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 bq29311 analog front-end (AFE) protection IC to maximize functionality and safety and minimize component count and cost in smart battery circuits. Using information from the bq2085-V1P3, the host controller can manage remaining battery power to extend the system run time as much as possible.

The bq2085-V1P3 uses an integrating converter with continuous sampling for the measurement of battery charge and discharge currents
