VDD

This is the main STUSB4500L power supply. Whatever the application is VBUS powered or not, VDD mandatory

connection is to USB power line (VBUS). The STUSB4500L can indeed work in dead battery mode, even for self-

powered application, in order to reduce power consumption to ZERO when the port is not attached, therefore

having no impact on application power leakage.
