Hello,
I have a custom board using tps65987D. When a device is plugged in the 5V is enabled and looking on the CC1 lines you can see some activity when a button is pressed on the Sink EVM board but no response comes from the TPS65987D.
Due to a fault on the board Drain 1's pad was shorted to GND internally so the traces were cut to isolate it and VBUS1. Could these being isolated cause cc1 to not communicate?
Kind Regards,
