TPS65987DDJ: Is it possible to change source/sink modes using a GPIO input on the PD?

Part Number: TPS65987DDJ

Hi,

We have an ARM based processor which control TPS65987DDJ through its I2C lines.

In our application, the PD is by default configured to have a 5V, 3A source and data role is UFP. And also we support to switch power role to a Sink on runtime instead of a source by issuing an I2C command called Swap to Sink or vice versa.

Rather than issuing an I2C command, I would prefer to switch the power roles using an GPIO input on the TPS65987DDJ side such as one of the input GPIO is logic-1, then act as a Sink and logic-0 acts as a Source. That would simplify our design in a way that instead of implementing whole I2C command chain, just need to control one IO.

Is it possible?

Regards,
