Hi team,

We plan to use this device like  port1 is sink and port 2 is source.

Is this configuration possible? Should we use external FET as either sink or source line?

Best regards,

    Hi,

    Yes, in the datasheet there should be a reference to how the power paths are connected. You can change the configuration how you described in the Global System Configuration register using the TPS6598x GUI. You may also take a look at the TPS65988EVM and reference the EVM User's Guide to configure the external power path if you would like.

    I would recommend referencing the Technical Reference Manual for more details about the register.

    Thank you,

    Hari
