Product details
Overview
HD3SS3220RNHT from Texas Instruments is a USB Type-C Dual Role Port (DRP) controller with integrated SuperSpeed 2:1 multiplexer, supporting USB 3.1 Gen1/Gen2 up to 10 Gbps, 3 A Power Delivery current advertisement/detection, and VCONN sourcing for active cables. It performs real-time cable orientation detection, role negotiation (DFP/UFP/DRP), and CC logic control in mobile phones, notebooks, and USB peripherals.
For engineers reviewing the HD3SS3220RNHT datasheet, HD3SS3220RNHT pinout, HD3SS3220RNHT application, or HD3SS3220RNHT equivalent, this device delivers verified USB Type-C DRP port control with integrated SS mux switching, adaptive common-mode tracking, and GPIO/I2C configurability - critical for compact, high-speed USB-C host/device designs requiring robust attachment detection and power mode signaling.
Technical Context
The HD3SS3220RNHT implements full USB Type-C Channel Configuration (CC) logic including attach/detach detection, plug orientation sensing via DIR output, and tri-level current mode signaling (900 mA / 1.5 A / 3 A). Its integrated 2:1 SuperSpeed mux supports bidirectional 10 Gbps data paths with <5 ps inter-pair skew and 8 GHz bandwidth.
It operates in three static or I2C-configurable modes (DFP-only, UFP-only, DRP), uses dual-supply rails (VDD5 = 4.5–5.5 V, VCC33 = 3.0–3.6 V), and features VBUS_DET input with 2.95–3.8 V threshold, open-drain outputs (ID, DIR, VCONN_FAULT_N), and thermal pad-equipped VQFN package for industrial ambient operation (–40°C to 85°C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| USB Data Rate | Supports USB 3.1 Gen1 (5 Gbps) and Gen2 (10 Gbps) - enables full backward compatibility and high-bandwidth peripheral connectivity. |
| Power Delivery Support | Advertises and detects Default (900 mA), Medium (1.5 A), and High (3 A) current modes - meets USB Type-C 15 W power requirements without external PD controller. |
| Integrated MUX | 2:1 SuperSpeed differential switch with 8 GHz bandwidth, <1.5 dB insertion loss at 5 GHz, and <20 ps inter-pair skew - preserves signal integrity for USB 3.1 eye diagram compliance. |
| CC Logic Functions | Performs cable orientation detection, role negotiation (DFP/UFP/DRP), VCONN sourcing, and audio/debug accessory mode support - eliminates need for discrete CC management circuitry. |
| Supply Voltages | VDD5 = 4.5–5.5 V (for CC/VCONN), VCC33 = 3.0–3.6 V (for logic/mux) - enables clean separation of analog and digital power domains. |
| Operating Temperature | –40°C to +85°C - qualified for industrial and mobile embedded applications including tablets and portable SSDs. |
| ESD Rating | ±2000 V HBM, ±1500 V CDM - ensures robustness during board assembly and end-user handling in consumer electronics environments. |
Pinout & Package
VQFN-30 (RNH) package, 2.50 mm × 4.50 mm body size, exposed thermal pad connected to GND per TI PowerPAD™ guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CC1, CC2 | Type-C Configuration Channel I/O | Detects attachment, orientation, role, and current mode via voltage thresholds - core interface for USB Type-C specification compliance. |
| DIR | Open-drain orientation indicator output | Signals cable flip state (0/1) to system MCU - enables dynamic SS lane routing without software polling. |
| ID | Open-drain attachment status output | Asserts low when DFP or DRP detects UFP attachment - provides hardware-triggered interrupt for port state machine transitions. |
| VBUS_DET | Analog input for system VBUS monitoring | Accepts 4–28 V via 900 kΩ external resistor - enables safe UFP attachment detection and VBUS presence validation before enabling power paths. |
| ENn_CC, ENn_MUX | Active-low enable controls | Independent gating of CC logic (ENn_CC) and SS mux (ENn_MUX) - allows ultra-low-power standby (5 µA) with selective subsystem wake-up. |
| TX1p/n, RX1p/n, TX2p/n, RX2p/n | SuperSpeed differential I/O pairs | Two independent SS lanes routed through internal 2:1 mux - supports reversible connector routing with adaptive common-mode tracking across RX/TX channels. |
| VCONN_FAULT_N | Open-drain VCONN overcurrent flag | Asserts low when VCONN current exceeds 225–375 mA - protects active cables and prevents system-level fault propagation. |
Key Features
| Feature | Design Value |
|---|---|
| DRP Mode with Try.SRC/Try.SNK | Automatically toggles between source/sink roles per USB Type-C spec - enables seamless host-peripheral role switching in docks and multi-function devices. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB Type-C DRP port controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TUSB544RNQT | Single-lane USB 3.1 Gen2 redriver (no CC logic or DRP control); requires external Type-C controller. | Used only for signal conditioning - cannot replace HD3SS3220RNHT's integrated port management and mux switching. | Select when SS signal boost is needed alongside a separate CC controller (e.g., TUSB1002A). |
| TPS65987D | Full USB Power Delivery 3.0 controller with PD PHY, BMC coding, and alternate mode support - includes CC logic but no integrated SS mux. | Supports USB PD communication, DisplayPort Alt Mode, and programmable policy engine - broader feature set but higher BOM cost and firmware complexity. | Choose when PD negotiation, e-marking, or Alt Mode (e.g., DP/HDMI) is required; HD3SS3220RNHT suffices for basic DRP + SS routing without PD. |
Compared with TUSB544RNQT and TPS65987D, HD3SS3220RNHT uniquely integrates DRP port control, 2:1 SS mux, and VCONN sourcing in a single 30-pin VQFN - reducing component count and PCB area for cost-sensitive USB-C host/device designs that do not require full PD stack or redriver functionality.

FAQ
What USB specifications does the HD3SS3220RNHT support?
The HD3SS3220RNHT supports USB Type-C 1.2 and USB 3.1 Gen1 (5 Gbps) and Gen2 (10 Gbps) specifications. It implements full Channel Configuration (CC) logic for attachment detection, cable orientation, role negotiation (DFP/UFP/DRP), and current mode signaling - all compliant with USB-IF test plans. It does not support USB Power Delivery (PD) communication or Alternate Modes like DisplayPort.
How does the HD3SS3220RNHT handle USB-C cable orientation detection?
The HD3SS3220RNHT detects cable orientation by monitoring voltage levels on CC1 and CC2 pins, then asserts the DIR pin (open-drain output) to indicate flip state (0 or 1). This DIR signal directly controls the internal 2:1 SuperSpeed mux to route TX/RX lanes correctly - eliminating software-based orientation polling and ensuring sub-microsecond lane reconfiguration upon plug insertion.
Can the HD3SS3220RNHT operate without I2C configuration?
Yes, the HD3SS3220RNHT supports full hardware-strapped operation using tri-level input pins: PORT (DFP/UFP/DRP mode), CURRENT_MODE (900 mA/1.5 A/3 A), and ADDR (I2C enable/disable). In GPIO mode, OUT1/OUT2 report detected current mode, and INT_N/OUT3 signals CC event interrupts - enabling complete USB-C port control with zero I2C firmware overhead.
What is the function of the VCONN_FAULT_N pin on the HD3SS3220RNHT?
The VCONN_FAULT_N pin is an open-drain output that asserts low when VCONN current exceeds the device's internal 225–375 mA limit. This signal alerts the system MCU to disconnect VCONN or throttle power, protecting active cables from overheating. The HD3SS3220RNHT integrates the VCONN power FET (RON = 1.25 Ω) and requires no external current-sense resistor.
Does the HD3SS3220RNHT support audio accessory mode?
Yes, the HD3SS3220RNHT supports both passive and charge-through audio accessory modes in UFP, DFP, and DRP configurations - unlike the HD3SS3220L variant which omits audio support. It detects audio adapters via CC pin voltage signatures and asserts INT_N/OUT3 to notify the host, enabling headset jack emulation without additional codec circuitry.
