Product details
Overview
FUSB308BVMPX from onsemi is a USB Type-C Port Controller (TCPC) with integrated USB Power Delivery (PD) Rev 3.0 support, compliant with USB Type-C Rev 1.3 and USB-PD Interface Spec Rev 1.0. It provides autonomous BMC PD packet handling, dual-role port (DRP) toggling, 10-bit VBUS ADC, and dual VBUS source control (SRC/SRC_HV) for desktop, wall adapter, and automotive USB-C power delivery systems.
For engineers reviewing the FUSB308BVMPX datasheet, pinout, applications, or equivalent options, key selection considerations include its QFN-16 package, I²C slave interface with 4 selectable addresses, integrated VCONN switch (3 W capable), manual/automatic CC line detection, and support for SOP*/SOP'/SOP" message types in USB-PD communication.
Technical Context
The FUSB308BVMPX implements a dedicated BMC physical layer with autonomous GoodCRC generation, automatic retry on failed transmission, and hardware-accelerated CRC32 validation. Its Type-C detection logic supports both manual Rp/Rd configuration and automatic DRP toggling via ROLECTRL register control.
Power management includes independent SRC (vSafe5V) and SRC_HV (high-voltage) load switch controls, programmable VCONN OCP (210.5 mA default), and VBUS monitoring via 10-bit ADC with configurable voltage alarms (VALARML/H_CFG). The device operates across −40°C to +105°C for automotive-grade reliability.

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB-C port controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STUSB4500QTR | Single-source VBUS control only; no SRC_HV output; supports USB-PD Rev 2.0 only; lacks VCONN switch. | Targeted at cost-sensitive 5 V/15 W adapters without HV PD or active cable support. | Select when HV sourcing and VCONN are unnecessary and automotive temp range is not required. |
| TUSB7320RGET | USB 3.1 Gen 1 hub controller with integrated TCPC; larger 40-pin QFN; requires external VCONN LDO; supports PD Rev 2.0. | Designed for USB data + power hub applications, not standalone TCPC use cases. | Choose only when simultaneous USB 3.1 data switching and PD control are needed in one IC. |
Compared with STUSB4500QTR and TUSB7320RGET, the FUSB308BVMPX uniquely combines automotive temperature range, dual VBUS source control, integrated VCONN switching, and USB-PD Rev 3.0 compliance - making it optimal for high-reliability, high-power USB-C endpoints where autonomous PD handling and compact footprint are critical.

FAQ
What USB-PD revision does the FUSB308BVMPX support?
The FUSB308BVMPX supports USB-PD Revision 3.0 Version 1.2 and complies with the USB-PD Interface Specification Revision 1.0. This enables full feature support including Programmable Power Supply (PPS), Adjustable Voltage PDOs, and extended data messages (chunked), all handled autonomously by the FUSB308BVMPX hardware without TCPM intervention.
Does the FUSB308BVMPX integrate a VCONN power switch?
Yes, the FUSB308BVMPX integrates a 3 W-capable VCONN switch that routes regulated power to either CC1 or CC2 based on cable orientation. It includes programmable overcurrent protection (OCP) via the VCONN_OCP register and monitors VCONN validity at a fixed 2.4 V threshold reported in PWRSTAT.VCONN_VAL - eliminating the need for external VCONN regulation circuitry.
How does the FUSB308BVMPX handle dual VBUS source control?
The FUSB308BVMPX provides two dedicated CMOS outputs: SRC for vSafe5V sourcing and SRC_HV for high-voltage sourcing (e.g., 9/15/20 V). Transition between them is controlled via the COMMAND register (e.g., 1000_1000b for HV enable), with automatic VBUS discharge and alarm reconfiguration - enabling safe, sequenced voltage handover during PD contract negotiation.
What is the operating temperature range of the FUSB308BVMPX?
The FUSB308BVMPX is rated for −40°C to +105°C operation, meeting automotive-grade environmental requirements. This extended range ensures reliable performance in under-dash vehicle charging modules, industrial power hubs, and thermally constrained desktop adapters - validated across full DC and transient electrical characteristics per datasheet Table 5.
Can the FUSB308BVMPX operate as a dual-role port (DRP)?
Yes, the FUSB308BVMPX supports automatic DRP toggling via the ROLECTRL register. When ROLECTRL.DRP = 1b, it autonomously alternates between Rp (source) and Rd (sink) termination on CC1/CC2 until attachment is detected. The resulting role (UFP/DFP) and orientation are reported in CCSTAT, enabling zero-latency role determination without TCPM polling.
