bq25618/bq25619 Single-Cell Buck Battery Chargers

Texas Instruments bq25618/bq25619 Single-Cell Buck Battery Chargers are highly integrated 1.5A switch-mode battery charge management and system power path management devices for a single-cell Li-Ion and Li-polymer battery. They feature fast charging with high input voltage support for a wide range of applications, including wearables, and earphone charging cases. The low-impedance power path optimises switch-mode operation efficiency, reduces battery charging time and extends battery run time during the discharging phase. The input voltage and current regulation, low termination current, and battery remote sensing deliver maximum charging power to the battery.
