Hi,
Please let me ask about VBUS condition to enable OTG. In page 24 of datasheet, it describe "VBUS is below VVBUS_UVLO" to enable OTG, but I think that it may be VINDPM threshold, not VVBUS_UVLO. Can you confirm it by using EVM? I actually confirmed it by using EVM on my bench.

Hi Joel,
Today I checked the threshold of VBUS voltage to enable OTG mode and found that it seems VINDPM setting is unrelated. But I actually confirmed that the OTG is enabled with approx. 3.2V VBUS that is higher than VVBUS_UVLOZ clearly. And after that, I tired to increase VBUS step by step, then OTG is not enabled with 3.48V.
I guess that the VBUS threshold to enable OTG is VVBUS_CONVEN, not VVBUS_UVLOZ. So can you also try this on your bench and discuss internally?
Best Regards,
Satoshi
