FUSB302TV01MPX - USB Type-C PD Controller, 14-WQFN | onsemi
MPN: FUSB302TV01MPX ✓ AktifFUSB302TV01MPX Genel Bakış
A USB Type-C controller is a specialized interface IC that manages the CC (Configuration Channel) pin negotiation, role detection, and power-delivery messaging between two attached Type-C ports. Within the broader hierarchy, the FUSB302T belongs to: USB Type-C port controller -> USB Power Delivery (USB PD) controller -> interface IC -> USB interface -> wired connectivity semiconductor. Its primary role is to act as the policy engine and BMC transceiver between a host MCU and the Type-C connector's CC1/CC2 pins, offloading the low-level USB PD protocol stack from the application processor.
Key features include support for USB Type-C 1.2 and USB PD 2.0/3.0 signaling on both CC lines, an integrated BMC transmitter/receiver with hardware preamble/EOP generation, I2C interface up to 1 MHz for host control, and dual-role capability selectable through firmware. The device operates from a 3.0 V to 5.5 V supply rail, draws a low standby current for always-on applications, and exposes interrupt/GPIO pins for attach, detach, and PD message events.
The FUSB302TV01MPX uses a mixed-signal architecture combining a 1.2V core digital logic block, analog CC line comparators with adjustable thresholds, and a BMC modem that handles 4b/5b symbol encoding, bi-phase-mark coding, and CRC-32 verification. This hardware offload frees the external MCU from tight real-time constraints and supports the full USB PD 3.0 extended message set, including PPS (Programmable Power Supply) and AVS (Adjustable Voltage Supply).
Typical applications include USB Type-C wall chargers, travel adaptors, automotive cigarette-lighter adaptors, laptop docking stations, and power adaptors. Its automotive-grade qualification makes it especially attractive for in-vehicle charging ports and infotainment USB-C jacks. The wide host support across STM32, NXP Kinetis, and Renesas RX platforms shortens firmware development cycles.
When designing with this device, pay close attention to CC pull-up/pull-down resistor selection to meet Type-C current advertisement (default, 1.5A, 3.0A). The VBUS discharge path must be sized to handle 20V at 5A per USB PD 3.0, and the CC lines require ESD protection rated to 8 kV contact / 15 kV air per IEC 61000-4-2 for robust consumer and automotive deployments.

Tipik Uygulamalar
FUSB302TV01MPX için uygundur 6 uygulamas: USB Type-C Wall Charger, Automotive Cigarette Lighter Adaptor, Travel Adaptor with Multi-Port PD, Laptop Docking Station USB-C Upstream Port, Power Adaptor with Programmable PPS, Industrial USB-C Diagnostic Port.
USB Type-C Wall Charger
The FUSB302TV01MPX's hardware BMC PD layer and USB PD 3.0 support make it well suited to fixed-voltage and PPS-capable wall chargers. Designers place the part between the 5V/20V switching converter and the Type-C receptacle's CC1/CC2 pins, using I2C from an entry-level MCU to advertise 5V/3A, 9V/2A, or PPS 3.3V-11V profiles. Its 3.0V-5.5V VDD range simplifies direct connection to the same 5V rail that feeds the VBUS discharge MOSFET. The 14-WQFN (2.5x2.5 mm) footprint keeps the charger PCB compact while exposing both CC lines for cable-orientation-agnostic operation.

Automotive Cigarette Lighter Adaptor
The FUSB302TV01MPX is AEC-Q100 qualified, which makes it the preferred Type-C PD controller for cigarette-lighter adaptors that must survive -40C to +85C automotive under-hood and cabin thermal profiles. It negotiates USB PD 3.0 fast-charge profiles (9V/3A, 12V/3A) directly from a 12V battery-fed buck-boost converter, while its integrated CC1/CC2 comparators detect cable attach and orientation. The 14-WQFN EP package offers good thermal dissipation for the always-on standby current budget required for USB-C wake-on-attach behavior in modern infotainment systems.

Travel Adaptor with Multi-Port PD
Travel adaptors combining USB-A legacy ports and a USB-C PD port benefit from the FUSB302TV01MPX's small 14-WQFN footprint and its I2C-based role configuration. The MCU on the adaptor can dynamically switch the part between Source role for PD output and DRP role for dual-role debugging during factory test. With on-chip CRC-32 and bi-phase-mark coding, the FUSB302TV01MPX handles USB PD extended messages (PPS, AVS) without burdening the host MCU, leaving headroom for additional legacy-port charging protocols such as Apple 2.4A or QC 3.0.

Laptop Docking Station USB-C Upstream Port
The FUSB302TV01MPX is widely used as the upstream-facing Type-C PD controller in laptop docks, where it negotiates a 20V/5A PD contract with the host laptop. Operating from the dock's internal 20V rail via a local 5V LDO, the part's VDD range (3.0V-5.5V) easily accommodates this configuration. The hardware BMC TX/RX block keeps firmware latency low even when the dock MCU is busy servicing DisplayPort alt-mode muxing, USB 3.1 hub enumeration, and ethernet offload. Its small 2.5x2.5 mm WQFN footprint allows placement directly behind the Type-C receptacle.

Power Adaptor with Programmable PPS
Programmable Power Supply (PPS) adaptors need a PD controller that supports PD 3.0 extended messages, which the FUSB302TV01MPX handles in hardware. Designers pair the controller with a wide-output buck-boost converter so the host MCU can issue continuous PPS requests from 3.3V to 11V at 20mV granularity. The FUSB302TV01MPX's I2C interface running up to 1 MHz provides low-latency feedback loop for PPS voltage adjustment, while its interrupt (INTn) pin wakes the MCU on every received PD message. The 14-WQFN package is well-suited to ultra-compact 30W-65W GaN-based adaptors.
Önerilen
Industrial USB-C Diagnostic Port
Industrial test equipment and programmable logic controllers increasingly expose a USB-C port for firmware update and field diagnostics. The FUSB302TV01MPX fits this role because its -40C to +85C operating range covers most industrial cabinets, and its I2C interface supports up to 1 MHz for fast firmware upload. The part's dual-role (DRP) capability, when reflashed via the V firmware option, allows the same port to act as a host during debug or as a sink when powered from a laptop. The 14-WQFN EP package's small footprint is ideal for sealed industrial enclosures where PCB area is at a premium.

Tasarım Notları
Do not route the CC1 and CC2 traces as a differential pair - they are independent single-ended lines that must be routed symmetrically but not coupled. Per the onsemi FUSB302T datasheet, CC trace length should be matched within 100 mils to ensure reliable attach detection, and both lines must include TVS diode protection (e.g., USBLC6-2SC6) rated to 8 kV contact / 15 kV air ESD per IEC 61000-4-2 for consumer and automotive robustness.
The 14-WQFN EP package exposes a thermal pad on pin 14 that must be soldered to a continuous ground copper pour on the top layer with at least 4 thermal vias to the inner/bottom ground plane. Estimated: at VDD=5V and continuous BMC transmission, internal dissipation is below 100 mW, so a small 10x10 mm copper pour keeps junction temperature rise under 10C. For sealed automotive enclosures, increase the copper pour to 20x20 mm for additional thermal margin.
Place the FUSB302TV01MPX within 10 mm of the Type-C receptacle's CC1/CC2 pads to minimize parasitic capacitance and stub reflections that can corrupt the BMC PD signaling. The I2C lines (SDA/SCL) should be routed as a 100 ohm differential pair with 22-33 ohm series termination near the MCU, and the INT_N line should be pulled up to the MCU's VDD rail with a 10 kohm resistor. Keep the VBUS sense trace short and away from switching node edges to prevent false attach/detach events.
The FUSB302TV01MPX VDD rail must be sourced from a low-noise LDO or the same 5V rail that feeds the VBUS discharge path; switching-node noise above 50 mVpp on VDD can corrupt the CC line comparators and cause false PD negotiation retries. Add a 1 uF X7R ceramic bypass capacitor within 3 mm of the VDD pin and a 10 uF bulk capacitor on the VBUS sense input per the onsemi reference design.
