Hi Thirunavukkarasu P,

Copy that, I will look into this case, but in the beginning, I need confirm with you about below questions.

What is the mean of 'VCC', I can't find the VCC pin in our TPS2549-Q1, you mean the OUT pin? Also, what is requirement of the OTG controller? Only the impedance?

Best Regards,

Kuno

Hi Kuno Wu, 

We are using this USB OTG controller (TPS2549IRTERQ1) IC in our IVI program. 

I mean VCC as the Input power to the IC (IN --> Pin 1)

Regards
Thiru.

Hi Thiru,

Got it, what is the test set up for your test? Set the EN to 0, and test the impedance of Pin1? Right?

Sorry, I am the first time to hear our customer need to pass the OTG, do you have any test spec for it?

Best Regards,

Kuno
