FUSB307BVMPX 개요
A USB Type-C Port Controller is a companion IC that sits between a system processor (acting as the TCPM) and the physical Type-C connector. It handles the time-critical analog and digital signaling that the host CPU cannot service deterministically - including attach/detach detection, cable orientation (CC pin polarity), USB-PD messaging on the Configuration Channel (CC) lines, and VBUS/VCONN gate driver control. The FUSB307B offloads these tasks so the TCPM only has to handle higher-layer policy decisions.
Key features include I2C interface for TCPM communication, integrated USB-PD Rev 1.0 message handling, manual attach/detach detection logic, dead-battery RD support, and dual-gate driver outputs for VBUS and VCONN MOSFETs. The 16-WQFN (3x3) package with exposed thermal pad supports compact PCB layouts in space-constrained designs such as laptops, tablets, and smartphone docking cradles.
Architecture-wise, the FUSB307B uses an internal state machine to manage USB-PD protocol timing without firmware intervention on the TCPC itself. This deterministic hardware implementation is critical for USB-IF compliance certification, where sub-millisecond response times on CC line events are required for interoperability with the wider Type-C ecosystem.
Typical applications include notebooks and laptops, USB Type-C docking stations, tablet PCs and 2-in-1 detachables, smartphone fast-charging adapters, and automotive USB Type-C infotainment ports. Up to four FUSB307B devices can be cascaded from a single TCPM via I2C, enabling multi-port designs. The onsemi community forum currently lists this part as EOL (case 216718), so verify last-time-buy status before committing to new designs.
When designing with this device, ensure proper sequencing of the upstream 3.3V and 1.2V rails before I2C access, and place the VBUS/VCONN gate-driver traces close to the external N-FETs to minimize parasitic inductance. Decouple VCC and VBAT pins with 1uF and 0.1uF ceramics as recommended in the onsemi datasheet.

일반적인 애플리케이션
FUSB307BVMPX 적합 용도: 6 애플리케이션s: Notebook and Laptop USB Type-C Ports, USB Type-C Docking Stations, Tablet and 2-in-1 Detachable PCs, Smartphone and Tablet Fast-Charging Adapters, Automotive Infotainment USB-C Ports, USB Type-C Power Bank and Hub Designs.
Notebook and Laptop USB Type-C Ports
The FUSB307BVMPX is a natural fit for notebook USB-C ports because it implements the USB-IF-defined TCPC role and USB-PD Rev 1.0 message handling entirely in hardware. With USB 3.0 data rates and dual VBUS/VCONN gate drivers, it can switch a 5V/3A Type-C port autonomously while the laptop EC handles only TCPM policy. The 16-WQFN (3x3 mm) package fits slim chassis designs where every square millimeter of PCB is at a premium, and up to four parts can be cascaded per TCPM for multi-port designs.

USB Type-C Docking Stations
USB-C docks often carry multiple Type-C upstream or downstream ports and need a deterministic TCPC that can negotiate PD contracts without latency spikes. The FUSB307BVMPX's hardware-based USB-PD Rev 1.0 stack handles message timing sub-millisecond, allowing the dock's TCPM to focus on DisplayPort Alt Mode and USB 3.x data muxing. The exposed-pad 16-WQFN package also tolerates the higher ambient inside an enclosed aluminum dock chassis. Docks that previously used this part are advised to verify last-time-buy stock for ongoing service.
추천
Tablet and 2-in-1 Detachable PCs
Tablets and detachable 2-in-1s need fast charging and DRP (dual-role port) behavior so the device can act as either sink or source. The FUSB307BVMPX supports DRP via its CC1/CC2 attachment logic and dead-battery RD advertising, which is critical for first-power-on charging. Hardware-attach/detach detection allows the tablet SoC to enter low-power states without missing Type-C events, extending battery life. The 3x3 mm WQFN footprint fits behind the docking pogo-pin array common in detachables.
추천
Smartphone and Tablet Fast-Charging Adapters
Wall-watt USB-PD adapters benefit from the FUSB307BVMPX's source-side capability because it can negotiate 5V/3A, 9V/2A, and 15V/1.5A PD contracts on the CC lines without firmware intervention. The integrated VBUS N-FET gate driver eliminates an external charge pump IC, lowering BOM cost in space-constrained adapter housings. VCONN support enables eMarker cable discovery for 5A cables. Designers should note the part's EOL status before launching new adapter SKUs and plan a migration to FUSB15201.
추천
Automotive Infotainment USB-C Ports
The FUSB307BVMPX is labeled 'AUTOMOTIVE USB TYPE-C' by Mouser and supports industrial -40C to +85C operation, but it is NOT AEC-Q100 qualified. It is therefore best suited to non-safety automotive subsystems (rear-seat entertainment, head-unit USB ports) where automotive-grade certification is not required. The dual gate drivers and CC line protection are useful in vehicles where frequent cable insertion cycles stress the Type-C connector.
추천
USB Type-C Power Bank and Hub Designs
Portable power banks and bus-powered hubs need a low-power TCPC to wake on attach and signal capacity to the source. The FUSB307BVMPX's dead-battery Rd mode and hardware attach detection let a power bank present itself correctly even with the internal cell depleted. The dual N-FET gate drivers integrate VBUS protection that would otherwise need a separate load switch, reducing BOM by 2-3 components. The 16-WQFN (3x3) package with exposed pad simplifies PCB thermal design in compact power banks.

주요 차별점
- Hardware-based USB-PD Rev 1.0 protocol stack (vs TUSB320 (TI))
- Up to 4 devices per TCPM via I2C cascade (vs FUSB302BVMPX (onsemi))
- Integrated VBUS and VCONN gate drivers (vs Discrete load-switch solution)
설계 노트
Estimated: VBAT and VCC each require a 1uF X7R ceramic bypass capacitor placed within 2 mm of the respective pin, plus a 0.1uF decoupling capacitor for high-frequency noise. The internal LDO generates 1.8V/3.3V for core logic - never drive VCC from an external rail or the part may latch. Power-up sequence requires VBAT stable before I2C transactions begin.
Route the CC1 and CC2 traces as 90-ohm differential-style with no sharp bends and keep them matched in length within 5 mm. Place external VBUS N-FETs and VCONN N-FETs within 5 mm of the gate-driver pins to minimize parasitic inductance, which can otherwise cause ringing on the VBUS rail during fast PD contract changes. The exposed pad must be soldered to a continuous ground plane for thermal dissipation.
Do not apply I2C clock before VBAT is stable - the TCPC will not respond and the TCPM may misconfigure the bus. The ADR0/ADR1 address strapping must use 1% resistors to avoid address collisions when cascading up to 4 TCPCs. VCONN must be decoupled with at least 1uF to source the 1W allowed for active cables, otherwise VCONN_FAULT will trigger.
Per onsemi community case 216718 (October 2026), the FUSB307B family is EOL with no direct replacement. For new designs, evaluate the onsemi FUSB15201 (PD 3.1 TCPC) or TI TUSB320 family. If you must use FUSB307BVMPX, place last-time-buy orders now while distributor stock remains, and qualify a second source in parallel to mitigate allocation risk.
