Hi,

Please change C546, C549, C565, C568 to 0.33uF, otherwise the schematic looks ok.

Thanks

David

Hi,

Since you are in the GPIO mode, I would have pullup/pulldown the CAD_SNK to disable/enable the AUX snooping.

Thanks

Hi David

Sorry what does this mean?

Hi,

The CAD_SNK goes to TP125 in the schematic. Please have 1k pullup to VCC and pulldown to ground option on the CAD_SNK so you can enable/disable the TUSB1146 AUX snooping in the GPIO mode as needed.

Thanks
