Other Parts Discussed in Thread: TPS65987D

I am designing a USB-C with USB2.0 OTG, Power sink 12V/5A, Powers source 5V/0.5A, and alternate mode Displayport source. Which part should I use, TPS65982 or TPS65987D? Can you review the schematics? Does GPIO provide an ID signal for USB 2.0 OTG?

I would suggest the TPS65987D, but either device will be sufficient for your design. However, if you want your device to be USB IF compliant, you should use the TPS65987D as the USB-IF is no longer running compliance testing on USB2 only devices after this summer

Adam,

Does TPS65987D or TPS65982 provide ID signal for USB OTG? Can you review the attached schematic, please?USB-C_Interface_sch_01.pdf

No neither device handles signal for USB OTG. They are PD controllers that handle Type-C PD messaging, and pass through any voltage provided to them that is negotiated on VBUS. And your schematic looks fine
