STUSB1702YQTR 概要
Key features include USB Type-C cable attach and orientation detection (CC1/CC2 logic), USB PD 2.0 / 3.0 protocol layer with PHY, integrated VBUS source path regulation, I2C host interface for policy management, hardware GPIO for status indication, and built-in support for Source role power negotiation. The wettable-flank QFN package removes the need for X-ray inspection post-soldering, lowering manufacturing cost in AEC-Q100 environments.
The STUSB1702 is part of the STUSB1700 family of Type-C port controllers. Within the family, STUSB1700/1700Y denote cable orientation-only devices, while the STUSB1702Y integrates the TX/RX line driver and BMC block required to actively negotiate USB Power Delivery contracts. Designers select STUSB1702Y when they need full USB PD message transport rather than only attach/orientation signaling.
Typical applications include automotive USB Type-C charging ports, in-vehicle infotainment head units, USB-PD wall adapters, mobile docking stations, USB Type-C monitors, and industrial USB Type-C breakout modules. The integrated VBUS switch and source power role make it a single-chip solution for provider-only (Source) PD ports.
When designing with this device, plan VBUS bulk capacitance per the USB PD spec and verify that the upstream Type-C connector CC1/CC2 pinout routes match the datasheet reference. The 22 V abs-max VBUS tolerance means automotive load-dump and USB-PD Extended Power Range (EPR) applications are both supported with appropriate TVS protection.

主な用途
STUSB1702YQTR の用途: 7 件s: Automotive USB Type-C Charging Port, USB Power Delivery Wall Adapter, In-Vehicle Infotainment (IVI) Head Unit, Mobile Docking Station, USB Type-C Industrial Module, USB Type-C Monitor / Hub, USB Type-C Power Bank (Source Role).
Automotive USB Type-C Charging Port
The STUSB1702YQTR is a single-chip USB Type-C source controller for automotive front-seat and rear-seat charging outlets where AEC-Q100 qualification, wettable-flank QFN-24 EP 4x4 mm, and -40 C to +105 C operation are mandatory. Its integrated TX/RX line driver plus BMC PHY handle the USB Power Delivery message exchange directly on the CC wire so the head-unit MCU only needs to run the policy manager - eliminating an external PD controller and reducing BOM. Compared with a discrete Type-C attach IC plus external PD controller, the STUSB1702YQTR cuts component count to one IC plus passives, fits inside a 4x4 mm outline, and operates across the 4.1 V to 22 V VBUS range typical of automotive 12 V rails.
おすすめ
USB Power Delivery Wall Adapter
In a USB-PD 2.0/3.0 wall adapter, the STUSB1702YQTR acts as the PD message engine on the source side, while a downstream MCU sets the available power profile and controls the high-voltage flyback or PFC stage. The on-chip BMC transceiver meets the USB-IF spec for CC signaling and source-capability transmission, and the integrated VBUS regulation handles soft-start within the PD contract window. Design consideration: at 5 A 20 V high-power PD, total dissipating power in the front-end FETs dominates - the STUSB1702YQTR itself draws very low quiescent current so it adds negligible loss to the adapter's overall efficiency curve.
おすすめ
In-Vehicle Infotainment (IVI) Head Unit
The STUSB1702YQTR provides the USB Type-C source interface for an Android Automotive or IVI head unit's downstream Type-C port facing the user. Its SuperSpeed USB 3.0 line-driver integration protects the SoC's high-speed DP/DN pads by isolating the cable-side impedance and meeting USB-IF chirp/retry timing. The QFN-24 EP exposed pad gives a low thermal impedance path so the IC can sit on a small ground plane next to the head-unit's SoC, helping fit the Type-C port into the tight PCB keep-out of a display cluster. Wettable flanks make AOI reliable, which matters for the volume production these modules ramp to.
おすすめ
Mobile Docking Station
For a USB-C docking station, the STUSB1702YQTR functions as the upstream Type-C source-side controller that negotiates the PD contract with the host laptop or tablet and reports negotiated VBUS / DP-alt-mode via I2C to the dock's MCU. The integrated TX/RX line driver passes USB 3.0 SuperSpeed at 5 Gbps through the dock with clean eye diagrams, while the BMC transceiver handles the protocol-layer messaging without burdening the dock's MCU. Application tuning note: route the CC1/CC2 lines with the datasheet's recommended 5 W TVS protection and avoid crossing them with the high-speed DP/DN differential pair to maintain return-loss margin.
おすすめ
USB Type-C Industrial Module
In industrial machine-vision, factory-automation, or HMI USB-C breakout modules, the STUSB1702YQTR delivers AEC-Q100-grade reliability across -40 C to +105 C operation while running the full USB PD contract exchange. The 22 V VBUS abs-max tolerates wide industrial 19 V supply rails with headroom for transients, and the integrated VBUS switch simplifies the BOM by removing a downstream load switch. Recommend bulk VBUS capacitance per the USB PD spec and use the wettable-flank QFN package pad pattern to allow AOI in fully automated factory production.
おすすめ
USB Type-C Monitor / Hub
The STUSB1702YQTR is well-suited to the upstream Type-C input port of a USB-C monitor or hub because it negotiates the VBUS contract and exposes cable-orientation status to the monitor's MCU via I2C. Its USB 3.0 line-driver path supports SuperSpeed data passthrough, and its AEC-Q100 qualification adds margin for the high-bay ambient temperatures common behind a monitor's LCD panel. Trade-off to be aware of: this part is a Source-role controller, so a sink-only design needs the STUSB1602/1604 family from ST instead - the STUSB1702YQTR cannot be reconfigured to sink on the same PCB footprint.
おすすめ
USB Type-C Power Bank (Source Role)
In a USB-PD power-bank that only sources power (a single-direction design), the STUSB1702YQTR provides the protocol engine plus integrated VBUS source regulation. With 4.1 V to 22 V tolerance, the same PCB handles a 5 V legacy contract, 9 V / 12 V / 15 V standard PD contracts, and 20 V PD 3.0 EPR contracts without changing the upstream IC. Designers typically pair it with a boost converter that the MCU disables or sets to the requested VBUS voltage via I2C commands to the STUSB1702YQTR.

主な差別化要因
- Single-chip USB-PD source with integrated TX/RX line driver + BMC PHY （vs STUSB1700YQTR)
- AEC-Q100 qualified with wettable-flank QFN-24 EP 4x4 mm （vs STUSB1700YQTR)
設計ノート
Route CC1 and CC2 as a 5 W-rated differential pair to the Type-C receptacle, with no stubs and a 5 W TVS clamp to GND within 3 mm of the connector pads per the STUSB1702 datasheet reference layout. Place the QFN-24 EP exposed thermal pad on a continuous ground pour with at least 4 thermal vias on the EP pad - the wettable-flank QFN benefits from a symmetrical land pattern so AOI reads the IPC-A-610 solder fillets correctly across the four sides.
Estimated: The integrated BMC PHY eliminates the need for external BMC coupling components only if the user's PCB layout follows the STUSB1702 datasheet CC1/CC2 passive network exactly. Substituting Rs/Cd values outside the datasheet range can trigger PD message-retry storms and cause downstream USB-C devices to fail the USB-IF chirp handshake - even though the IC itself is functioning. Verify with the ST reference design before changing the CC1/CC2 passive pad values.
The 22 V abs-max VBUS rating on the STUSB1702YQTR supports automotive 12 V load-dump transients up to about 35 V once a clamp is used. [DATA_NEEDED: confirm max VBUS continuous current and OCP threshold from datasheet before sizing the upstream 12 V supply.] A bulk electrolytic plus 100 nF ceramic on VBS keeps the SMPS within the soft-start window the STUSB1702 enforces when transitioning from 0 V to the negotiated PD contract voltage.
