FUSB302B
Overview
The FUSB302B is a flexible USB Type-C controller designed to handle Configuration Channel (CC) detection and USB Power Delivery (PD) communication. It enables hardware to implement Port Side Detection, orientation sensing, and Dual-Role Port (DRP) functionality through a simple I2C interface. By offloading the low-level BMC PHY and protocol timing to the FUSB302B, engineers can add full PD 2.0 support to systems using standard microcontrollers.
Why Choose This Part
The device features an autonomous DRP toggle and automatic GoodCRC response, which significantly reduces the software overhead and real-time requirements on the host processor. It also includes AEC-Q100 Grade 2 qualification, making it suitable for automotive environments requiring robust USB-C connectivity.
Applications
Key Specifications
Getting Started
To begin development, connect the FUSB302B to a host microcontroller via the I2C bus and integrate a software driver to manage the PD policy engine. Evaluation is typically performed using the FEBFUSB302B_CH01R evaluation board, which demonstrates full PD negotiation and power path control.
