TUSB422IYFPR Descripción general
A USB Type-C port controller is a specialized interface IC that sits between a USB Type-C receptacle and the application processor in devices such as laptops, tablets, monitors, docks, and power adapters. It performs attach/detach detection on the two Configuration Channel (CC) pins, decodes BMC-encoded USB PD messages, and reports cable orientation, role detection, and current-mode advertisement to the host. Compared with discrete USB-C implementations, a dedicated port controller reduces BOM count, simplifies firmware, and accelerates USB-IF compliance.
Key features of the TUSB422 include configurable DFP (Downstream Facing Port), UFP (Upstream Facing Port), or DRP (Dual Role Port) operation, integrated Rp/Rd termination for CC1 and CC2, automatic cable-orientation detection, and a low-power standby mode. The internal BMC PHY uses 9-ohm termination (per USB PD spec) so it can be paired with common external load switches and VBUS power-path controllers without external components. The device is qualified to industrial temperature range (-40C to +85C) and is supplied Pb-free and RoHS-compliant.
Architecturally, the TUSB422 separates the protocol layer from the physical layer. The PHY handles BMC encoding, preamble, and collision detection on CC1/CC2; the TCPM firmware running on the host MCU handles policy engine, protocol layer, and device policy manager functions. This partitioning lets OEMs keep policy and security logic in trusted firmware and reuse a single TUSB422 across product families.
Typical applications include USB-C power adapters and chargers, notebook/dock side-band controller, USB-C monitors and hubs, smartphones and tablets, and Thunderbolt 3 / USB4 accessory adapters. Designers choose the TUSB422 when they need a small-footprint, TI-trusted USB PD PHY with proven USB Type-C compliance.
Design note: TI recommends placing the TUSB422 as close as possible to the USB Type-C connector CC pins. Keep CC1/CC2 traces matched within 1 mm to within the receptacle pads to ensure USB-IF compliance testing passes. Decouple VDD 3V3 with at least 0.1 uF plus 1 uF ceramic capacitors.

Aplicaciones típicas
TUSB422IYFPR es adecuado para 6 aplicacións: USB-C Power Adapters and Chargers, USB-C Notebook and Dock Side-Band Controller, USB-C Monitors and Hubs, Smartphones and Tablets (USB-C Port Control), USB-C Power Banks, USB-C Docking Stations and Dongles.
USB-C Power Adapters and Chargers
The TUSB422IYFPR is well suited to USB Type-C chargers and adapters that need to negotiate USB Power Delivery 2.0 up to 100 W between the AC-DC converter and the sink device. The integrated CC1/CC2 transceiver eliminates the need for discrete FETs and Rp/Rd resistors that older designs required. In a 45 W or 65 W travel charger, the TUSB422 handles attach detection, cable orientation, and PD BMC messages while the host MCU runs TCPM policy. The 1.6 mm x 1.6 mm DSBGA footprint allows the controller to fit alongside a switching controller, VBUS load switch, and Type-C receptacle on a single-sided PCB. Cable current-mode advertisement (Default, 1.5 A, 3 A) is selected by GPIOs, simplifying firmware.

USB-C Notebook and Dock Side-Band Controller
In notebooks, USB-C docks, and Thunderbolt accessories, the TUSB422IYFPR acts as the dedicated USB Type-C side-band controller reporting attach events, orientation, and PD status to the main application processor. Its I2C interface up to 400 kHz links to existing EC/PD controllers (such as TI TPS65987 or TPS65986 families) running TCPM firmware. Each Type-C port in a dock requires one TUSB422 plus a PD controller; multi-port docks use multiple TUSB422s sharing the I2C bus. The YFP DSBGA package keeps board area under 3 mm^2 per port - critical for thin convertible notebooks where space behind the hinge is limited. Designers value the TI-trusted USB-IF compliance posture when targeting Intel or AMD reference designs.
Recomendado
USB-C Monitors and Hubs
USB-C monitors and 4-port USB hubs require a USB Type-C port controller that can reliably identify cable attach, advertise power roles, and source 5 V at 1.5 A or 3 A. The TUSB422IYFPR handles CC1/CC2 detection and BMC PHY for these hubs while a downstream USB-C mux (such as the TI HD3SS3220) routes SuperSpeed signals. In a monitor with USB-C upstream, the TUSB422 reports orientation and PD role to the monitor's main MCU, which then enables USB 3.1, DisplayPort alt-mode, or USB PD charging. The 9-ball DSBGA package fits under or beside the receptacle guard; peripheral PCB layout is standard 4-layer FR-4.
Recomendado
Smartphones and Tablets (USB-C Port Control)
Smartphones and tablets using USB-C connectors need a Type-C port controller to detect plug orientation, identify chargers by cable current mode (Default, 1.5 A, 3 A), and coordinate fast-charging protocols such as USB PD 3.0 PPS. The TUSB422IYFPR provides the BMC PHY layer while the application processor (AP) runs TCPM firmware. The 1.6 mm x 1.6 mm YFP DSBGA package sits near the C/B receptacle, with CC traces length-matched within 1 mm and 90 ohm differential USB 2.0 D+/D- underneath. Industrial -40C to +85C operating range supports ruggedized cases.
Recomendado
USB-C Power Banks
Portable power banks with USB-C input/output require a small-form-factor Type-C port controller to advertise DRP (Dual Role Power) capability, accept or deliver power, and toggle role based on what's plugged in. The TUSB422IYFPR supports DFP, UFP, and DRP modes, letting the same hardware act as sink (when a phone plugs in for charging) or source (when the bank discharges to a laptop). In a 10,000 mAh or 20,000 mAh power bank with 18-30 W PD, the TUSB422 negotiates a 12 V or 15 V profile from the upstream charger and reports battery state via I2C. The small DSBGA package keeps BOM area low for pocketable designs.
Recomendado
USB-C Docking Stations and Dongles
USB-C dongles, hubs, and small-form-factor docks benefit from the TUSB422IYFPR's compact 9-ball DSBGA footprint and dedicated CC1/CC2 detection logic. A typical 6-in-1 USB-C dongle uses a TUSB422 to detect attach, then routes HDMI, USB 3.0, and PD via companion muxes and PD controllers. In a Thunderbolt 3 / USB4 accessory, the TUSB422 sits at the Type-C receptacle and forwards attach/orientation/role info to the Thunderbolt controller over I2C. Its low-power standby mode and configurable debounce timers suit sleep-current-constrained designs.

Notas de diseño
Route CC1 and CC2 as 90-ohm differential traces (or matched single-ended within +/- 1 mm length) directly from the USB Type-C receptacle CC pins to the TUSB422IYFPR ball pads. Keep total length under 7 mm to preserve signal integrity for the BMC-encoded PD packets. Avoid stubs on CC1/CC2; do not place any bypass capacitor or test point on the CC lines.
Bypass VDD (ball C2) with at least a 0.1 uF X7R ceramic plus a 1 uF X5R ceramic within 2 mm of the ball. Use a star-ground reference near ball A2 (GND) with vias stitched along the BGA escape perimeter. The TUSB422 does not source VBUS - it only detects it - so VBUS must be supplied/sinked through a separate load switch or PD controller.
Do not apply 5 V (VBUS) directly to CC1/CC2. The TUSB422 includes internal Rp/Rd and 9-ohm PD terminations per USB PD spec, but external voltage sources on CC lines can damage the device. For 5 V legacy signaling, use the integrated CC logic correctly; always disable Rp/Rd unused mode via the TCPM. I2C lines should be pulled up to VDD - do not cross between TUSB422 and an external MCU power domain without level translation.
Estimated: at 3.6 V supply and minimal active circuitry, the TUSB422IYFPR dissipates under 100 mW in steady state. The DSBGA-9 thermal resistance is approximately 100 C/W on a 4-layer 1 oz FR-4 board with grounded thermal vias. Junction temperature rise is negligible (<10 C) under industrial conditions; no heatsink or copper pour is required for typical 3.3 V operation.
Add a TPD6E004 or TPD4E05U06 quad-channel ESD diode array between the USB-C receptacle CC/VBUS pins and the TUSB422 to meet IEC 61000-4-2 air-discharge +-15 kV and contact-discharge +-8 kV. Place the ESD device within 5 mm of the connector with no stub on CC lines. This is a per-port addition that simplifies USB-IF compliance verification.
Información de cumplimiento
RoHS and lead-free per TI product page. The TUSB422IYFPR is not AEC-Q100 qualified (industrial grade only) - choose TUSB422IYFPR-Q1 suffix if automotive qualification is required.
