STUSB1600 Présentation
An interface controller IC such as the STUSB1600 sits in the USB Type-C protocol stack between the USB host/device controller (e.g., a USB-PD or USB 3.x controller) and the physical Type-C receptacle. It handles the cable attach, role detection (DFP/UFP/DRP), plug orientation (CC1/CC2), and VCONN presence, offloading these hardware-level tasks from the main controller. In the broader IC taxonomy it is a USB interface IC within the interface and connectivity category, distinct from a USB-PD controller that handles higher-voltage power negotiation.
Key features include integrated VBUS voltage monitoring, VBUS source-gate control for 5 V power switches, dead-battery Rd pull-down behavior, BC1.2 detection support, and a non-volatile memory (NVM) that stores default configuration without external components. The CC lines carry short-to-VBUS protection rated to handle mis-wiring faults up to the connector tolerance, while an I2C interface provides host access to status registers and configuration. The device supports both host (DFP), device (UFP), and dual-role (DRP) port modes selectable through NVM settings.
The STUSB1600 architecture combines a hardware attach state machine with a small microcontroller-compatible I2C interface for status reporting. Its 24-pin QFN package is compact for space-constrained hubs, dongles, and docking stations. Operating temperature is rated for -40 C to +85 C industrial conditions, and the device ships as STUSB1600AQTR (tape and reel) for volume production.
Typical applications include USB Type-C ports on laptops, monitors, docking stations, USB hubs, smartphones, power banks, and embedded systems. Engineers also use it as a stand-alone accessory controller for cable adapters and HDMI-over-USB-C dongles.
When designing with the STUSB1600, verify that the desired port role (DFP/UFP/DRP) is correctly programmed in NVM and that the upstream 5 V source is rated for the port's load. Per the manufacturer datasheet, ensure CC1/CC2 ESD protection is added externally for production-grade robustness.

Applications typiques
STUSB1600 convient pour 7 applications: USB Type-C Port on Laptop Docking Stations, USB-C Hub Downstream Ports, USB-C Wall Chargers and Travel Adapters, Smartphone and Tablet USB-C Accessory Detection, USB-C Dongles and Active Adapters, Industrial and Embedded USB Type-C Ports, USB-C Power Bank Output Ports.
USB Type-C Port on Laptop Docking Stations
The STUSB1600's integrated short-to-VBUS protection on CC1/CC2 and 5 V VBUS source-gate control make it well suited to docking-station USB Type-C upstream ports. The 24-pin QFN (4x4 mm) footprint fits behind Type-C receptacles without crowding the high-speed USB 3.x lanes, while the I2C interface lets the docking-station MCU monitor attach, orientation, and VCONN state for proper Billboard enumeration. The on-chip short-to-VBUS protection reduces external TVS component count, which lowers BOM cost and improves mean-time-between-failure metrics in field-deployed enterprise docks.
Recommandé
USB-C Hub Downstream Ports
In 4-port and 7-port USB-C hubs, the STUSB1600 can be deployed per port to provide individual attach detection, orientation, and VCONN support. Each STUSB1600's integrated NVM allows engineers to program different port roles (DFP/UFP/DRP) for each downstream port without external logic. The -40 C to +85 C industrial temperature range supports hubs deployed in signage, kiosks, and industrial-control applications, while the small 4x4 mm QFN enables high port density on the hub PCB.
Recommandé
USB-C Wall Chargers and Travel Adapters
USB-C wall chargers and travel adapters benefit from the STUSB1600's minimal external component count and integrated VBUS source-gate drive, which can directly control an N-channel power MOSFET on the 5 V rail. The on-chip short-to-VBUS protection is particularly valuable in charger designs where cable abuse and connector wear can cause fault conditions. Its QFN-24 (4x4) package fits the dense PCBs of compact 30 W to 65 W GaN chargers.
Recommandé
Smartphone and Tablet USB-C Accessory Detection
Smartphones and tablets use the STUSB1600 in UFP or DRP mode to detect cable orientation, attach events, and VCONN-powered accessories such as active cables or HDMI adapters. The integrated CC-line debouncing and 5 V VBUS monitoring allow the application processor to remain in low-power states until a meaningful attach event occurs. The compact QFN-24 package is well suited to slim handheld enclosures where every square millimeter counts.
Recommandé
USB-C Dongles and Active Adapters
Active USB-C adapters (HDMI, DisplayPort, Ethernet, SATA) use the STUSB1600 to negotiate Type-C attach and detect cable orientation before switching high-speed signal lanes through a redriver or retimer. The I2C status registers let the adapter MCU detect CC-logic states and accessory modes (Audio Adapter, Debug Accessory) for firmware-driven signal routing. The QFN-24 (4x4) form factor fits the small dongle PCBs typical of travel-grade adapters.
Recommandé
Industrial and Embedded USB Type-C Ports
Industrial PCs, HMI panels, and factory automation controllers integrate the STUSB1600 to provide ruggedized USB Type-C ports with industrial -40 C to +85 C operating range. The integrated short-to-VBUS protection and VCONN support reduce external protection component count on noise- and fault-prone industrial factory floors. The STUSB1600's I2C interface enables diagnostic logging of attach/detach events for predictive maintenance systems on connected equipment.
Recommandé
USB-C Power Bank Output Ports
USB-C power banks deploy the STUSB1600 to provide intelligent 5 V output port detection, allowing the bank to recognize sink attachments and trigger appropriate output-enable behavior. The VBUS source-gate control can directly drive an N-channel protection MOSFET, simplifying the power-path design. The QFN-24 (4x4 mm) footprint and low quiescent current help power banks achieve longer idle shelf life while keeping PCB area small.

Principaux différenciateurs
- Integrated short-to-VBUS protection on CC lines (vs TUSB320IRWBR)
- Compact 4x4 mm QFN with integrated VBUS source-gate driver (vs FUSB302MPX)
- Programmable NVM with multiple port roles (vs STUSB1602AQTR)
Notes de conception
Route CC1 and CC2 as a 90-ohm differential pair with no vias and minimal stubs to preserve signal integrity for USB Type-C attach and orientation detection. Place the STUSB1600 within 10 mm of the Type-C receptacle to keep the CC trace lengths short. The exposed pad (EP, pin 24) MUST be soldered to a continuous ground plane with multiple thermal vias to meet the package thermal and electrical specifications.
Add a 10 uF X5R ceramic bypass capacitor close to the VDD pin (pin 22) plus a 100 nF high-frequency decoupling cap. The VCONN supply rail (pin 6) requires a local 4.7 uF capacitor to support inrush transients when powering active electronically marked cables. Verify the upstream 5 V source can deliver at least the port-rated current with adequate headroom for hot-plug events.
Keep high-speed USB 2.0 D+/D- lines and SuperSpeed TX/RX lanes physically separated from the CC traces to minimize crosstalk. Place the I2C SDA/SCL pull-up resistors (typically 4.7 kohm to VDD) close to the host MCU side rather than the STUSB1600 side to avoid contention during multi-master systems.
Do not assume the default NVM configuration matches your target port role - the STUSB1600 ships with a default that may differ from your design intent. Program the NVM during production test before first power-up. Also note the device is rated for 5 V VBUS only; applying USB-PD voltage above 5 V without an external OVP will damage the IC and downstream circuitry.
