BQ25176K Overview
The BQ25176K is an integrated 800mA linear charger for 1-cell Li-Ion, Li-Polymer, and LiFePO4 batteries targeted at space-limited portable applications. The device has a single power output that charges the battery. The system load can be placed in parallel with the battery, as long as the average system load does not prevent the battery from charging fully within the safety timer duration.
