[原创] ST STUSB4710 USB PD控制器解决方案

ST公司的STUSB4710是USB供电( PD)控制器新系列产品,不需要MCU就能连接到UFP或DRP,提供5个定制的电源数据目标(PDO),5个通用I/O和一个集成的放电通路,完全和 USB Type-C™ rev 1.2以及USB PD rev 2.0兼容,主要用在AC适配器和电源,智能插座和墙适配器,电源集线器和坞站,显示器和任何的Typs-C源设备.本文介绍了STUSB4710主要特性,功能框图,应用电路,以及评估板STEVAL-ISC003V1主要特性,框图,电路图,材料清单和PCB设计图.

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.

STUSB4710主要特性:

• USB power delivery (PD) controller
• Type-C attach and cable orientation detection
• Single role: provider - DFP
• Full hardware solution - no software
• I2C interface (optional connection to MCU)
• Support all USB PD profiles: up to 5 power data objects (PDO)
• Configurable startup profiles
• Integrated VBUS voltage monitoring
• Internal and/or external VBUS discharge path
• Short -to-VBUS protections on CC pins (22 V) and VBUS pins (28 V)
• Wide power supply input: − VDD = [4.1 V; 22 V]
• Temperature range: -40 °C up to 105 °C
• Fully compatible with: − USB Type-C™ rev 1.2
− USB PD rev 2.0
STUSB4710应用:
• AC adapters and power supplies for: computer, consumer or portable consumer applications
• Smart plugs and wall adapters
• Power hubs and docking stations
• Displays
• Any Type-C source device

评估板STEVAL-ISC003V1

The STEVAL-ISC003V1 evaluation board is a ready-to-use USB PD source using the STUSB4710 and ST1S14 ICs. It is used to demonstrate the features of the STUSB4710 controller by converting a single-voltage power supply into a Type-C power delivery source.

The STUSB4710 controls the Type-C port ensuring power delivery advertising and negotiation, controls the DC-to-DC converter and power paths, and monitors VBUS voltage.

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

The various LEDs indicate the operating status of the STUSB4710 and USB PD port. The USB PD port is pre-configured with five different PDO voltages, covering all main applications (5 V, 9 V, 12 V, 15 V and 20 V).
