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 device attachment to power negotiation, including VBUS discharge and protections.

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.

评定板STEVAL-ISC004V1

The STEVAL-ISC004V1 evaluation board is a ready-to-use USB PD source based on STUSB4710A and ST1S14 ICs. It demonstrates how to convert a fixed voltage DC power input into a USB PD variable voltage output.

The STUSB4710A acts as a Type-C port interface that ensures power delivery advertising and negotiation, drives the DC-to-DC converter and power paths, and monitors VBUS voltage.

The ST1S14 device manages the step down conversion from the DC input port to the negotiated VBUS voltage.

The various LEDs indicate the operating status of the STUSB4710A and USB PD port. The USB PD port is pre-configured with five different PDOs to address a broad range of applications (5V, 9V, 12V, 15V and 20V).
