Hi, Was planning to implement a design based on STUSB4500. have some queries about the working of STUSB4500 under different conditions.

STUSB4500 Dual power supply and communication circuitry enabling option using ATTACH pin

STUSB4500 ATTACH pin use for detection of Cable attached to the Type C port

Hi, As a part of our new product, we have decided to run the product on PD capability. So, we have decided the product to be developed with two USB PD ports, so that one port can be used for Wall PD charger and other port for PD by laptop.
