TUSB320HAIRWBR 개요
A USB Type-C Configuration Channel Logic IC is a state-machine controller that sits between a USB Type-C receptacle and the application processor or USB controller. Its job is to negotiate attach/detach events, cable orientation (CC1/CC2 polarity), role (host vs device), and current advertisement (default 500 mA, 1.5 A, or 3 A) through the CC1/CC2 pull-up and pull-down signalling defined by the USB-IF Type-C specification. Higher up the hierarchy it is an Interface IC > USB Interface IC; below it is the CC PHY layer.
Key features include: integrated 5.1 kΩ CC pull-up resistors that can be toggled for DRP toggle, hardware MODE pin configuration (no firmware needed), active-high enable (EN) pin for power sequencing, low standby current with a dedicated low-power mode, and HBM ESD protection on CC pins. The X2QFN-12 RWB package keeps the device under 3 mm² footprint, ideal for compact dongles, hubs, and embedded platforms.
Typical applications are any 5 V / 3 A USB Type-C ports that need a low-BOM CC controller: travel chargers, USB Type-C dongles, adapters, hubs, docking stations, smartphones, tablets, and notebooks. Because it operates as a standalone state machine with no MCU required, it is well-suited to cost- and board-area-sensitive designs.
Design consideration: place the 100 nF decoupling capacitor within 2 mm of VCC and keep the CC traces short, matched, and away from switching nodes to preserve signal integrity. A 0 Ω or ferrite series resistor on VBUS is optional but recommended to limit inrush current at attach.

일반적인 애플리케이션
TUSB320HAIRWBR 적합 용도: 7 애플리케이션s: USB Type-C Wall Charger, USB Type-C Adapter / Dongle, USB Type-C Hub, Notebook / Tablet Type-C Port, USB Type-C Docking Station, Industrial / IoT USB-C Data Port, USB Type-C Audio Accessory.
USB Type-C Wall Charger
The TUSB320HAIRWBR is a strong fit for USB Type-C wall chargers because it advertises up to 3 A of VBUS current without any firmware or MCU. According to TI documentation, the device's integrated 5.1 kΩ CC pull-up and hardware MODE pin selection let a designer implement a 5 V/3 A Type-C source with three resistors and one decoupling cap. Placed between the Type-C receptacle and the regulator feedback, it negotiates the highest current the device attached can draw, reducing charge time.

USB Type-C Adapter / Dongle
For USB Type-C to legacy adapters (USB-A, HDMI, DisplayPort), the TUSB320HAIRWBR's small X2QFN-12 package and standalone operation keep the BOM minimal. According to the TI TUSB320 datasheet, MODE configuration as UFP allows the adapter to sink 5 V at up to 3 A from a Type-C host without any external MCU. Pairing it with a USB 2.0 mux like HD3SS3220 enables a compact Type-C-to-A dongle.
추천
USB Type-C Hub
In a multi-port USB Type-C hub, each downstream port can use a TUSB320HAIRWBR configured as DFP to advertise 1.5 A or 3 A current per port. Per the TI datasheet, the device handles port attach/detach autonomously and supports DRP toggling if a port needs to support dual-role devices. The active-high EN pin allows the hub controller to power-gate unused ports and lower standby consumption.
추천
Notebook / Tablet Type-C Port
Notebooks and tablets can use the TUSB320HAIRWBR as a low-cost CC controller for downstream Type-C ports that do not require full USB PD negotiation. According to the TI datasheet, when configured as a DRP, the part automatically toggles between source and sink roles, ideal for convertible 2-in-1 designs that need both charging input and device-mode output. The industrial -40 C to +85 C range covers all notebook thermal environments.
추천
USB Type-C Docking Station
The TUSB320HAIRWBR can serve as the entry CC controller in a docking station where one Type-C upstream port connects to the host and downstream ports sink power. Per TI documentation, MODE3 selection of 3 A advertisement allows the dock to negotiate the full 5 V/3 A budget from the host while still using a standalone CC controller without a hub MCU. The 1.6 × 1.6 mm X2QFN footprint keeps the upstream port compact.
추천
Industrial / IoT USB-C Data Port
Industrial IoT gateways and edge devices often expose a USB Type-C port for service, firmware update, or local data exchange. The TUSB320HAIRWBR's industrial -40 C to +85 C rating and hardware-only configuration make it suitable for these environments. Per the TI datasheet, MODE-selected DRP operation allows the device to enumerate as either host or device depending on what is plugged in, simplifying service-port design without firmware.
추천
USB Type-C Audio Accessory
USB Type-C analog audio adapters need a CC controller that can configure the port as an audio accessory sink. Per the TI TUSB320 datasheet, the device's MODE configurations support the audio accessory states defined in the USB Type-C specification, with CC1/CC2 both pulled up to indicate a Sink device. The X2QFN-12 footprint allows this to fit inside a 3.5 mm-to-USB-C dongle housing alongside an audio codec.

설계 노트
Place a 100 nF X7R 6.3 V decoupling capacitor within 2 mm of the VCC pin. The exposed thermal pad (EP) MUST be soldered to a copper pour connected to GND; do not leave it floating, as it provides the primary thermal path and a low-impedance ground reference for the CC comparators. CC1 and CC2 traces should be length-matched (within 1 mm) and routed away from switching nodes and magnetic components.
Do not connect the MODE pins to an MCU GPIO without a pull-down/up at power-up; the device latches the MODE configuration on rising edge of VCC and a floating pin can latch into an undefined state. If you intend to change roles at runtime, you must toggle VCC or use the EN pin to reset the device. Connecting both MODE1 and MODE2 to GND at all times places the part in DFP (Source) by default.
Keep CC1 and CC2 trace capacitance below 5 pF to GND and below 0.5 pF between them to avoid degrading the Type-C 400 kHz BMC signal. Series ferrite beads on CC lines are NOT recommended because they distort the high-frequency BMC edge. If common-mode filtering is required, place a common-mode choke BEFORE the ESD diode and keep the differential trace short.
VBUS discharge is handled internally; however, an external 100 kOhm pull-down on VBUS is recommended per Type-C spec to ensure VBUS drops below 0.8 V within 650 ms during detach. The 3.3 V supply to VCC should be derived from VBUS through a 100 mA LDO to allow the part to remain alive briefly after VBUS removal and complete the discharge handshake.
