bq25600/bq25600C/bq25600D 3 A Switch-Mode Battery Chargers

Texas Instruments' bq25600, bq25600C, and bq25600D are I²C controlled 3 A single-cell battery chargers

Image of Texas Instruments' bq25600/bq25600D 3 A Switch-Mode Battery ChargersTexas Instruments'  bq25600, bq25600C, and bq25600D devices are highly-integrated 3 A switch-mode battery charge management and system power path management devices for single-cell Li-Ion and Li-polymer batteries. The low impedance power path optimizes switch-mode operation efficiency and reduces battery charging time. The I²C serial interface with charging and system settings make the devices a truly flexible solution.
