STUSB4710 Stand-alone USB PD controller (with short-to-VBUS protection) Features USB power delivery (PD) controller Type-C attach and cable orientation detection Single role: provider Full hardware solution - no software 2 I C interface (optional connection to MCU) Support all USB PD profiles: up to 5 power data objects (PDO) Configurable start-up profiles Integrated V voltage monitoring BUS Internal and/or external V discharge path BUS Short -to-V protections on CC pins (22 V) and V pins (28 V) BUS BUS Wide power supply input: V = 4.1 V 22 V DD Temperature range: -40 C up to 105 C Fully compatible with: USB Type-C rev 1.2 USB PD rev 2.0 Certification test ID: 1000125 (QFN24) Applications Product status link AC adapters and power supplies for: computer, consumer or portable consumer applications STUSB4710 Smart plugs and wall adapters Power hubs and docking stations Displays Any Type-C source device Description The STUSB4710 is a new family of USB power delivery controllers communicating over Type-C configuration channel pins (CC) to negotiate a given amount of power to be sourced to an inquiring consumer device. The STUSB4710 addresses provider/DFP devices such as notebooks, tablets and AC adapters. The device can handle any connections to a UFP or DRP without any MCU attachment support, from the device attachment to power negotiation, including V discharge and protections.

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 the device connection Discover and configure V : Type-C low, medium or high current mode BUS Resolve cable orientation Negotiate a USB power delivery contract with a PD capable device Configure the power source accordingly Monitor V , manage transitions, handle protections and ensure user and device safety BUS 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.
