Texas Instruments  BQ25910YFFR

The BQ25910 is an integrated three-levelswitch-mode parallel battery charge management device for single cell Li-ion and Li-polymerbatteries. Utilization of the three-level converter maintains highest switch-mode operationefficiency while reducing solution footprint and increasing power density. The device supports fast chargingwith high input voltage for a wide range of portable devices. The solution integratesreverse-blocking FET (QBLK), and four switching FETs(QHSA, QHSB, QLSB,QLSA). The I2C serial interface with charging andsystem settings makes the device a truly flexible solution.
