Hi,

Can you please share the project file for this device?

Also can you please tell me what DFP device you are connected too?

Thank you,

Kevin

Hi

below is the project file Wiko_TBT3_TR_PD_BB_FW_0507_V003.pjt

The DFP device That I connected to is the notebook

Thanks!

Seems like current draw maybe high. Does this happen consistently or intermitently.

Hi

Yes, the peak current of the host is high

This happen intermitently.

How can I optimize it?Can I increase the percentage of peak current?or can I increase the Over Current Clamp timeout value?

Thanks!

Hi,

Hi,

Are you still seeing a fail rate at 150% peak current?

This should help here.

Thank you,
