Overview

The FUSB302TVMPX is an automotive-grade USB Type-C controller designed to handle CC interface detection and Power Delivery (PD) protocol communications. It allows a host processor to manage USB Type-C connectivity, including Dual-Role Port (DRP) negotiation and VCONN switching, via a standard I2C interface.

Why Choose This Part

This controller is AEC-Q100 qualified and features an autonomous DRP toggle that reduces host processor overhead. It integrates essential CC logic, including VCONN over-current limiting and automatic GoodCRC packet responses, into a small 2.5mm x 2.5mm WQFN package.

Applications

Automotive Infotainment
Enables USB Type-C and Power Delivery for vehicle head units and passenger charging ports.
USB PD Power Banks
Manages the negotiation of high-power charging profiles between the battery system and attached devices.
Industrial Dual-Role Ports
Supports autonomous DRP toggling for industrial equipment that acts as both a power source and a sink.
Smartphone Accessories
Provides the physical layer for USB PD 2.0 communication in compact form-factor peripherals.

Getting Started

Implementation requires a host microcontroller with an I2C master and a GPIO for the FUSB302 interrupt line. Engineers should utilize the onsemi-provided driver firmware to handle the USB PD state machine, as the IC performs the physical layer (PHY) and some protocol timing but relies on software for policy management.
