STUSB4710AQ1TR Descripción general
A USB PD controller is a power-management IC that negotiates voltage and current contracts between a Type-C source (such as a wall adapter or docking station) and a sink device. Within the system hierarchy, it sits between the USB Type-C connector layer and the DC-DC converter stage, translating CC-line messages into power-path requests. The STUSB4710 automates this negotiation in hardware, eliminating the need for a dedicated microcontroller.
Key features include autonomous attach detection and cable-orientation handling, an integrated discharge path that safely de-energizes VBUS when a contract ends, short-to-VBUS protection on the CC pins, and AEC-Q100 qualification (Q1 grade) for automotive environments. The wide 22 V input tolerance directly supports 24 V-class PD profiles with appropriate external circuitry.
Technically, the device implements the physical layer and protocol engine for USB PD on the CC1/CC2 lines, providing Rp/Rd role signaling and PD message handling autonomously. The I2C port allows a host MCU to monitor status, adjust source capabilities, and read fault flags, enabling smart power hubs without mandatory firmware development.
Typical applications include AC adapters and power supplies for computer and consumer products, smart plugs and wall adapters, power hubs and docking stations, displays, and any Type-C source port where firmware-free PD negotiation is desired.
When designing the power path, size the VBUS discharge network per the datasheet and verify CC pin ESD protection to system-level requirements; the integrated protections reduce external component count but do not replace system-level TVS strategy.

Aplicaciones típicas
STUSB4710AQ1TR es adecuado para 6 aplicacións: AC Adapters and Power Supplies, Smart Plugs and Wall Adapters, Power Hubs and Docking Stations, Displays and Monitors, Automotive USB-C Charging Ports, Generic Type-C Source Devices.
AC Adapters and Power Supplies
The STUSB4710AQ1TR is purpose-built for AC adapters and power supplies serving computer, consumer, and portable consumer products. Its autonomous hardware negotiation eliminates the firmware development and certification burden of MCU-based PD stacks, while the 4.1 V to 22 V supply range natively covers the full USB PD voltage span negotiated at 5V/9V/12V/15V/18V/24V. The integrated VBUS discharge path ensures the output capacitor bank is safely drained when a contract ends or the cable is unplugged, meeting PD sink discharge expectations without extra circuitry. Short-to-VBUS protection on the CC lines guards the controller against fault events common in adapter connectors, improving field reliability and reducing external protection component count in space-constrained adapter housings.
Recomendado
Smart Plugs and Wall Adapters
In smart plugs and wall adapters, the STUSB4710AQ1TR provides firmware-free USB-C PD source capability where board area and BOM cost are tightly constrained. The 3x3 mm QFN-16 footprint fits miniaturized wall-wart housings, and AEC-Q100 (Q1) qualification gives headroom for the elevated ambient temperatures and humidity cycling typical of wall-plate installations. Because attach detection and cable orientation are handled autonomously, no host processor is needed even in simple products; the I2C port can be left unconnected or used for production calibration. The integrated discharge path satisfies PD safety requirements for de-energizing VBUS when a phone or tablet is removed, avoiding the external discharge MOSFET and resistor networks otherwise required.
Recomendado
Power Hubs and Docking Stations
Multi-port power hubs and docking stations benefit from the STUSB4710AQ1TR's stand-alone operation: each Type-C source port can be served by one controller, distributing the PD negotiation load away from a central MCU and simplifying hot-swap behavior. The controller reports attach, contract, and fault status over I2C, allowing a hub microcontroller to manage total power budgeting across ports while each port negotiates independently at 5V/9V/12V/15V/18V/24V. Short-to-VBUS CC protection is particularly valuable in docking environments where connectors experience frequent mating cycles and accidental contact with charged cables. The integrated discharge path accelerates safe re-negotiation between successive sink attachments, improving perceived responsiveness of shared desks and hot-desk installations.
Recomendado
Displays and Monitors
USB-C monitors use PD source controllers to deliver upstream power to connected laptops while carrying DisplayPort video over the same cable. The STUSB4710AQ1TR handles the power-contract side autonomously at up to 24 V-class profiles within its 22 V supply rating, letting the monitor's main board set high-wattage contracts (for example 20 V) for notebook charging. Cable orientation detection ensures the contract establishes regardless of plug flip, and the short-to-VBUS protection tolerates hot-plug events at the monitor's easily accessed front panel. The firmware-free operation removes a software dependency from the monitor firmware release cycle, while optional I2C monitoring lets the display scaler track charging status for on-screen-indicator user interfaces.

Automotive USB-C Charging Ports
With AEC-Q100 qualification, the STUSB4710AQ1TR addresses in-vehicle USB-C charging modules for infotainment systems and rear-seat passenger ports. Automotive cabins demand robust connector protection: the controller's CC short-to-VBUS protection handles faulted cables and foreign objects, and its autonomous operation guarantees PD negotiation even during CAN-bus or host-MCU sleep states, enabling charge-before-ignition behavior. The 22 V maximum supply tolerates automotive load-transient conditions on the accessory rail with appropriate front-end filtering, while the integrated discharge path meets PD de-energization requirements when a passenger unplugs a device. One controller per port also allows independent left/right seat port contracts without a shared firmware state machine.
Recomendado
Generic Type-C Source Devices
Any product implementing a USB-C source port - battery packs, kiosks, industrial equipment, test fixtures - can use the STUSB4710AQ1TR as the plug-and-play PD front end. Because negotiation is autonomous, adding a compliant Type-C port reduces to connecting CC1/CC2, VBUS sense, and supply pins, dramatically shortening design cycles for teams without USB-IF firmware expertise. The I2C interface remains available for products that want to expose contract information, enforce vendor power policies, or log fault events. The integrated discharge path keeps the port compliant when devices are removed mid-contract, and Q1-grade qualification plus the 4.1 V to 22 V operating window give margin across consumer and industrial supply conditions alike.

Notas de diseño
The STUSB4710 is NRND per ST Community (February 2026). For new designs, do not start with this part - consult ST's recommended firmware-free successor first. For legacy production, secure last-time-buy stock from authorized distributors (LCSC showed only 110 units as of 2026-10-19) and consider a dual-footprint strategy: the STUSB4700AQ1TR shares the QFN-16 footprint but requires an external VBUS discharge circuit, so reserve board area for that network if a swap may be needed.
Place the controller close to the Type-C receptacle to keep CC1/CC2 traces short, matched in length, and routed away from high-dv/dt switching nodes of the downstream DC-DC converter. Provide a solid low-inductance ground via the QFN backside pad with an array of vias to the ground plane. ESD on the VBUS line is not fully handled by the IC's short-to-VBUS protection - add system-level TVS diodes rated for the full 20 V PD contract voltage per USB PD and IEC system-level ESD practice.
The 4.1 V to 22 V operating range allows direct connection to a VBUS-derived rail, but verify the upstream DC-DC converter can regulate down to the lowest negotiated contract (5 V) while the controller stays above its 4.1 V minimum under all load and line conditions. Estimated: at a 20 V contract delivering 3 A, converter dissipation - not the controller - dominates thermal design; the QFN-16 controller itself dissipates minimal power. Confirm minimum-load behavior of the main converter, since PD contracts can drop to near-zero current.
