Description
General part information
BQ28400 Series
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.
The bq28400 communicates with the system host via a two-wire SMBus 1.1 compatible interface, providing high-accuracy reporting and control of battery pack operation. The FET drive and TSSOP package enable a lower cost and small footprint solution along with a simple layout and routing on narrow pack PCBs.
