Part Number: TPS65987D

I test TPS65987D and TPS65982EVM.

When I connect 987D and Non-PD sink, 987D send Source_Capabilities message 150 times.

When I connect 982 and Non-PD sink, 982 send Source_Capabilities message 200 times.

Would you tell me why the retry times of 987D is less than 982?

Hi Anderson,

For 987D we found that 150 times is enough times to send the Source Caps retry for all cases.

Thank you,
Eric

Hi
Thank you.
Can I change this value?
For example change to 200 times.

Hi Anderson,

No, this value cannot be changed. There is no need to change it.

Thanks,
Eric
