    Hi Jimmy, 

    PMP41083 design is intended for sink-only application (from BQ perspective, this system is only enabled for Forward Mode to charge the battery).

    If you need DRP (Dual Role Power) capabilities, please refer to PMP41062 which also uses TPS25751+BQ25756: https://www.ti.com/tool/PMP41062 

    Let us know if you have any further questions or concerns!

    Thanks and Regards,
