The TPS65987Ds opponent is a DRP so I want to controll the TPS65987Ds power roll.
Like making the TPS65987D to a sorce and a sink at the required timing.
So I want to know if I can controll this power roll by using I2C.
And I also want to know if I can controll this power roll by only using hardware controll.
Hi Kei-san,
TPS65987D can be configured to be a DRP using the Application Customization Tool, for quick tutorials on how to configure TPS65987D you can check out this link: https://www.ti.com/video/6122862051001
If your system has a MCU that act as a host controller to TPS65987D, you can use I2C to send 4cc commands to force TPS65987D to do a power role swap to either source or sink (see excerpt from the Technical Reference Manual below, linked here https://www.ti.com/lit/ug/slvubh2b/slvubh2b.pdf?ts=1699292152476&ref_url=https%253A%252F%252Fwww.ti.com%252Fproduct%252FTPS65987D):
Thanks and Regards,
