FUSB307BMPX 概述
An LDO (Low-Dropout) linear regulator is a type of voltage regulator that maintains a stable output voltage even when the input voltage is very close to the output voltage. USB Type-C Port Controllers with USB-PD fit into the broader hierarchy of USB interface ICs, themselves part of interface ICs that bridge processors to physical connectors. The FUSB307B acts as a standardized TCPC companion to a TCPM, offloading time-critical Power Delivery state-machine handling while letting the host processor manage policy and high-level decisions.
Key features of the FUSB307BMPX include integrated USB Type-C Rev 1.3 detection circuitry with manual attach/detach detection, autonomous handling of time-critical USB-PD messaging, support for up to four Type-C ports when multi-plexed by a TCPM, and I2C control interface for register access, GPIO control, and status polling. The 16-pin WQFN package with exposed pad enables compact PCB layouts in space-constrained mobile and laptop designs where every square millimeter counts.
Architecture-wise, the FUSB307B pairs a hardware USB-PD protocol layer (BMC-encoded CC signaling on the Configuration Channel lines CC1/CC2) with a software-accessible register map mapped through I2C. This hardware/software partitioning lets the TCPM run policy and source-power negotiation while the FUSB307B executes the deterministic time-budget tasks defined by the USB-IF TCPC specification, including GoodCRC timing and Hard Reset signaling.
Typical applications include notebook USB-C charging ports, docking stations with multiple Type-C sinks, tablet and 2-in-1 convertible power paths, USB-PD chargers, and smartphone fast-charge adapters. The device is well suited wherever a standardized TCPC interface is needed and the system architect already uses a discrete TCPM such as a microcontroller or an embedded controller running compliant TCPM firmware.
When designing with this part, ensure the I2C pull-ups are sized for the chosen bus speed (100 kHz Standard or 400 kHz Fast Mode) and that the CC1/CC2 lines have the appropriate Type-C Rp/Rd or pull-down/up scheme required by the desired Source/Sink role. The exposed thermal pad must be soldered to a sufficient ground copper pour to meet the package's thermal and electrical performance.

典型应用
FUSB307BMPX 适用于 6 应用s: Notebook USB-C Charging Port, Docking Station Multi-Port Hub, Tablet and 2-in-1 Convertible Power Path, USB-PD Wall Charger Adapter, Smartphone Fast-Charge Type-C Port, USB-C Monitor and Display Hub.
Notebook USB-C Charging Port
The FUSB307BMPX is well suited to a notebook USB-C charging port because it acts as a TCPC, offloading the USB-PD protocol layer (BMC messaging on CC1/CC2, GoodCRC timing, Hard Reset sequencing) from the embedded controller. This lets the TCPM focus on policy and battery-charger coordination while the FUSB307B executes the deterministic 1 ms-typical timing tasks defined by USB-PD. The 16-WQFN (3x3) package fits the small Type-C connector footprint inside a slim chassis, and the -40 C to +85 C range handles the thermal environment between the keyboard deck and the bottom cover.
推荐
Docking Station Multi-Port Hub
In a docking station with multiple USB-C downstream ports, the FUSB307BMPX provides a low-cost standardized TCPC front end per port, with up to four ports multiplexed through a single TCPM. The integrated Type-C Rev 1.3 attach/detach detection enables manual or software-driven cable-attach events to wake the dock host without polling overhead. Compared to a fully integrated USB-PD controller per port, using a TCPC architecture with the FUSB307BMPX drops BOM cost and PCB area while keeping policy centralized in the TCPM firmware stack.
推荐
Tablet and 2-in-1 Convertible Power Path
The FUSB307BMPX fits a tablet or 2-in-1 convertible's Type-C power path because it implements the standardized TCPC interface, allowing the SoC or EC TCPM to control charging direction (sink vs source) and USB-PD contracts up to 100 W. The 16-WQFN (3x3 mm) package with exposed pad provides thermal headroom for the 3-5 V CC logic when the device enters fast-charge mode. The I2C control interface at 400 kHz Fast Mode gives the EC sufficient bandwidth for status polling during high-frequency role swap events.
推荐
USB-PD Wall Charger Adapter
A USB-PD wall charger can use the FUSB307BMPX as the TCPC front end to a small TCPM that sets the source power rule (5 V/3 A, 9 V/3 A, 15 V/3 A, or 20 V/3.25 A). The FUSB307B's autonomous BMC encoder handles the physical-layer USB-PD messaging, freeing the charger MCU to manage thermal foldback, cable compensation, and protection. The 3x3 mm QFN package saves board area inside the dense wall-wart PCB, and the exposed pad ties to a copper pour for thermal relief at 60 W and above.
推荐
Smartphone Fast-Charge Type-C Port
Smartphone fast-charge ports handling QC+PD or proprietary protocols like VOOC benefit from the FUSB307BMPX acting as a TCPC bridge between the application's TCPM firmware and the USB Type-C connector. The part's integrated Type-C Rev 1.3 attach/detach detection with manual control accelerates cable-attach latency at the OS layer, critical for 18-65 W fast-charge handshakes. The 3x3 mm WQFN keeps the BOM footprint minimal compared to discrete CC controller designs and supports the -40 C to +85 C range for outdoor or vehicle-mount use cases.
推荐
USB-C Monitor and Display Hub
The FUSB307BMPX serves as a TCPC in a USB-C monitor or display hub where the panel's USB-PD port handles alt-mode entry (DisplayPort), USB 3.0 lanes, and power negotiation in parallel. Up to four Type-C ports can be multiplexed via TCPM for downstream-facing ports on the monitor. The TCPC role is highly advantageous here because alt-mode policy requires tight coordination with the GPU/SoC, which the TCPM host running Linux/ChromeOS/Android keeps in one place; the FUSB307B just executes the standardized USB-PD protocol layer on each port.

设计说明
Solder the WQFN-16 exposed thermal pad (pin 16 / EPAD) to a ground copper pour of at least 25 square millimeters to meet the datasheet's thermal performance and to provide a low-impedance return path for the high-frequency CC1/CC2 signals. Place the I2C pull-ups (typically 4.7 kohm to VDD) within 10 mm of the SDA/SCL pins and keep the bus traces shorter than 50 mm to avoid signal-integrity issues at 400 kHz Fast Mode.
Do not assume the FUSB307BMPX is a stand-alone USB-PD controller. It is a TCPC and requires an external TCPM that runs the policy state machine and issues commands over I2C according to the USB-IF TCPC specification. Pointing it at a generic USB-PD controller host without TCPM firmware support will not negotiate a power contract.
The CC1/CC2 lines carry BMC-encoded USB-PD messages with rise/fall times on the order of 300 ns. Keep CC1/CC2 traces short and matched within 1 mm, route them on the same layer, and avoid vias. Place the Type-C connector within 8-10 mm of the FUSB307B pins to minimize reflections and meet the USB Type-C Rev 1.3 TSEC rise/fall specifications.
VDD should be decoupled with a 1 uF ceramic capacitor placed within 2 mm of the VDD pin, plus a 0.1 uF high-frequency bypass. The FUSB307B communicates VBUS presence through its VBUS monitor pin; if your design does not connect VBUS to the monitor pin, you must disable the related interrupt in software to avoid spurious wake events.
