Hi, I designed the PCB where used STUSB4500. I encountered a problem: when I plug USB Type-C connector, USB PD adapter disconnects from my PCB. Could you advise what may reason to disconnect USB PD adapter?

Resolved! Will the STUSB4500 assert (pull low) the ATTACH pin if it is connected to a USB 2.0 port? For example in the case a USB 2.0-A to USB-C cable is used where there is no host USB PD communication on the CC pins and only 5V appears on VBUS.

Also, will the VBUS_EN_SNK pin get asserted (pulled low) in this case, allowing the power path to enable 5V from the USB 2.0 cable to power the device?
