Functional description

The STUSB4710 is an autonomous USB power delivery controller optimized as a provider.

It offers an open-drain GPIO interface to make direct interconnection with a power

regulation stage.

The STUSB4710 offers the benefits of a full hardware USB PD stack allowing robust and

safe USB PD negotiation in line with USB PD standard. The STUSB4710 is ideal for

provider applications in which digital or software intelligence is limited or missing.

The STUSB4710 main functions are:



Detect the connection between two USB ports (attach detection)



Establish a valid host to device connection



Discover and configure VBUS: Type-C low, medium or high current mode



Resolve cable orientation



Negotiate a USB power delivery contract with a PD capable device



Configure the power source accordingly



Monitor VBUS, manage transitions, handle protections and ensure user and device

safety

Additionally, the STUSB4710 offers 5 customizable power data objects (PDOs), 5 general

purpose I/Os, an integrated discharge path, and is natively robust to high voltage peaks.
