描述 Description

The STUSB4700 is a new family of USB power delivery controllers communicating over Type-C? configuration channel pin (CC) to negotiate a given amount of power to be sourced to an inquiring consumer device.

The STUSB4700 addresses provider/DFP devices such as notebooks, tablets and AC adapters. The device can handle any connections to a sink or DRP without any MCU control, from the device attachment to power negotiation, including VBUS discharge and protections.
