    Hi Sudheer,

    TI currently does not have a battery charger with integrated CCx lines for USB-C communication.  A 2 chip solution would be BQ25616 with TUSB320.  TI's higher current charger's expect to charge a battery pack with pack protector that opens when V(BAT)<2.5V, not a bare cell.

    Regards,

    Jeff

    Thanks Jeff,

    USB Lines will be used for OTG data purpose hence can you suggest the chip without D+ and D- Lines.

    Regards,

    HI Sudheer,

    A USB-C source requires communication over the CCx lines in order to provide 5-V.  The D+/D- lines are used to determine output power capability of legacy USB BC1.2 ports only for the first 2 seconds after initial power up and then data communications.  BQ25616 is the still the best standalone option.

    Regards,

    Jeff
