24VQFN Lithium Battery Charger IC 3A 4.2V BQ24296RGET Original

 BQ24296RGET SMD LED Chip Battery Chargers IC Lithium Ion/Polymer 24-VQFN

Charger IC Lithium Ion/Polymer 24-VQFN (4x4) IC BATT CHG LI-ION 1CELL 

Its low impedance power path optimizes switch-mode operation efficiency, reduces battery charge time and

extends battery life during discharging phase. The I2C serial interface with charging and system settings makes

the device a truly flexible solution.
