BQ28400 集成电量监测计和电池保护管理与 SBS

BQ28400 描述

The bq28400/bq28401 device is a fully integrated gas gauge and analog monitoring management solution that provides protection and control for 2-series cell Li-Ion battery packs in a single TSSOP package.

Implementing the optimum balance of quick response analog hardware-based monitoring and control along with an integrated fast CPU provides the ideal pack-based or in-system Li-Ion battery solution. The bq28400/bq28401 also provides flexible user programmable settings stored in flash memory for control of critical system parameters such as overcurrent, short circuit, under/overvoltage, and over/undertemperature conditions.

The bq28400/bq28401 communicates with the system host via a two-wire SMBus 1
