FUSB302TVMPX 개요
A USB Type-C controller is a specialized interface IC that sits between a host processor (or embedded MCU) and the USB Type-C connector's Configuration Channel (CC) pins. The FUSB302T family integrates the BMC physical layer of USB Power Delivery, allowing a small external MCU to negotiate PD contracts, swap power roles, and select alternate modes without requiring a full USB PD stack on the host. The device reduces BOM cost and firmware complexity compared to integrating a complete PD PHY.
Key features include USB Type-C 1.2 and USB PD 2.0 specification compliance, support for source, sink, and DRP roles, integrated BMC PD encoding/decoding, interrupt output for host wake-up, and an I2C interface (up to 400 kHz) for configuration. The 14-WQFN package with exposed thermal pad achieves a compact 2.5x2.5 mm footprint suited for space-constrained mobile and travel-adapter designs. Operating temperature range is -40C to +105C, qualifying the part for harsh-environment and automotive applications.
Architecturally, the FUSB302T separates the CC-line physical interface from the upper-layer protocol, communicating with the host MCU via I2C registers and a single alert/interrupt pin. Reference firmware is available from onsemi for multiple embedded platforms, accelerating time-to-market. The PD physical layer is implemented in dedicated hardware so the host MCU only handles policy engine state transitions, greatly reducing firmware overhead.
Typical applications include USB Type-C wall chargers, travel adapters, smart Type-C cables and docks, automotive head-unit chargers, monitor and hub USB-C inputs, and any embedded system that needs to negotiate up to 100 W over a Type-C connector while keeping firmware footprint small. The AEC-Q100 automotive grade qualification suits EV charging accessories and in-cabin infotainment power rails.
When designing with the FUSB302TVMPX, ensure that the CC1/CC2 pins are protected with ESD diodes rated at or above 8 kV HBM contact discharge, and place the device close to the Type-C receptacle to minimize CC trace length. Use onsemi's reference schematic and I2C firmware libraries for fastest compliance with USB Type-C and USB PD test suites.

일반적인 애플리케이션
FUSB302TVMPX 적합 용도: 7 애플리케이션s: USB Type-C Wall Chargers, Automotive Cabin USB Chargers, Travel Adapters and Power Banks, USB-C Monitor and Hub Inputs, Smart Type-C Cables and Dongles, Industrial USB-PD Machine Controllers, USB-C Charging for Headphones and Docks.
USB Type-C Wall Chargers
The FUSB302TVMPX is well-suited to USB Type-C wall chargers that need to negotiate PD contracts up to 60-100 W. Its integrated BMC PD physical layer handles source-role messaging so a low-cost MCU only runs the Type-C policy engine. AEC-Q100 qualification and -40C to +105C operation support enclosed-charger thermal margins even at sustained 100 W loads. The 14-WQFN 2.5x2.5 mm footprint enables compact charger housings, and onsemi reference firmware on common MCUs shortens USB-IF compliance testing. Place the FUSB302TVMPX within 5 mm of the Type-C CC pins to minimize parasitic capacitance on the CC lines.

Automotive Cabin USB Chargers
Within automotive cabin USB chargers the FUSB302TVMPX serves as the Type-C port manager with AEC-Q100 reliability, integrating CC detection, orientation, VCONN switching, and BMC PD messaging. The -40C to +105C industrial temperature grade handles dash-mounted charger modules that experience solar loading and winter cold-soak. A host MCU (e.g., an automotive-grade Cortex-M) uses I2C to command SRC/SNK/DRP roles, allowing the same PCB to support both power-source and power-sink ports. Reference designs from onsemi cover 15 W and 27 W automotive channel variants, enabling rapid platform reuse across OEM programs.
추천
Travel Adapters and Power Banks
Travel adapters and power banks gain USB Type-C 100 W PD capability with the FUSB302TVMPX because the integrated BMC PD block and the host MCU form a complete DRP-capable Type-C port. Its 14-WQFN EP package is small enough to fit multi-port travel designs while delivering firmware-updatable PD contracts. The device's source-sink flexibility lets the same hardware work as a power bank (SRC), a sink-side device (SNK), or DRP for laptop-to-phone reverse charging. Onsemi reference code paths support common MCU platforms (STM32, NXP LPC, ESP32), reducing time-to-market for adapter product families.

USB-C Monitor and Hub Inputs
In USB-C monitor and hub inputs, the FUSB302TVMPX enables the sink role of USB PD negotiation so a monitor can draw up to 100 W from a host laptop while simultaneously providing downstream charging to peripherals. The integrated CC detection eliminates the need for a separate Type-C cable orientation IC. The host MCU reads the negotiated PD contract via I2C to configure downstream buck-boost converters. The 2.5x2.5 mm 14-WQFN footprint fits the monitor's interior behind the I/O panel without competing with main SoC heat. Reference designs support MST hub operation alongside PD input, simplifying dual-role hub implementations.
추천
Smart Type-C Cables and Dongles
Within smart Type-C cables and active dongles, the FUSB302TVMPX adds USB PD awareness in a footprint small enough for inline cable assemblies. Inside an E-mark cable the device negotiates the cable's identity, current rating, and alternate-mode support through the BMC PD protocol, asserting VCONN to power the cable marker IC. In active dongles (HDMI, DP-alt, Ethernet) the same PHY routes Alt-Mode sideband signaling under MCU control. The 14-WQFN EP's 2.5x2.5 mm footprint suits the tight inline cavity of slim cable designs, and onsemi reference firmware is available for cable applications.
추천
Industrial USB-PD Machine Controllers
Industrial USB-PD machine controllers, including factory-automation handhelds and PoE-style test fixtures, benefit from the FUSB302TVMPX because AEC-Q100 / -40C to +105C operation withstands cabinet thermal cycling. Acting as a sink or DRP, the device negotiates up to 100 W from the upstream USB host so the industrial gadget's battery can charge quickly while also powering a heavier bus. The interrupt pin provides host wake-up on Type-C attach events, critical for low-duty-cycle sensor nodes. Onsemi releases register maps and compliance test firmware, enabling the lab to generate USB-IF reports in-house.

USB-C Charging for Headphones and Docks
Audio docks and high-end headphones that move to USB Type-C charging use the FUSB302TVMPX to handle sink-side PD negotiation with the upstream charger or laptop. The integrated CC detection gives the dock awareness of orientation and Type-C current advertisement, allowing intelligent upstream advertising for faster charge acceptance. In docking stations supporting 100 W upstream, the FUSB302TVMPX negotiates with the host laptop so that downstream ports receive stable 5 V/9 V/15 V/20 V to power peripherals. The 14-WQFN EP footprint slots into space-constrained dock PCBs alongside audio DSP, Bluetooth radios, and high-current charging ICs.

설계 노트
Place the FUSB302TVMPX within 5 mm of the Type-C connector CC1/CC2 pins to keep CC trace capacitance under 5 pF, which is required for USB PD compliance. Keep CC traces symmetric in length and avoid routing them over the ground plane split. The exposed thermal pad (pin 14) MUST be soldered to a 1 mm x 1 mm GND copper pour with at least three thermal vias to the inner GND plane for heat spreading.
Decouple VDD (pin 7) with a 100 nF X7R ceramic capacitor placed within 2 mm of the pin, plus a 4.7 uF bulk capacitor on the 5 V rail. Place the 100 nF cap on the top layer for minimum loop inductance. The VCONN output (pin 8) requires an external 5 V source fed through the internal switch - do not exceed 5.5 V on this pin or the protection clamp will engage.
Do not connect the FUSB302TVMPX CC1/CC2 pins directly to the Type-C connector without ESD protection - use a TVS diode array rated at least 8 kV HBM contact (e.g., ESD8004mutagen). Without proper ESD protection field failures are common. Also ensure the I2C bus pull-ups are 4.7 kohm for 100 kHz standard mode or 2.2 kohm for 400 kHz fast mode; weaker pull-ups cause intermittent NACK errors.
Route INT_N and I2C lines away from switching power nodes and VCONN if it toggles; even small coupling can trigger false interrupts. Keep VBUS sense traces short; a long VBUS trace picks up noise from the high-current path and confuses attach/detach detection. Maintain a guard ring around the CC pins to suppress crosstalk from adjacent high-speed USB 2.0 differential pairs.
