General Description

The bq28400 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 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.
