ONFUSB303BTMX
Overview
The FUSB303BTMX is a fully autonomous USB Type-C port controller that supports Source, Sink, and Dual Role Port (DRP) configurations. It implements the latest Type-C Rev 1.3 specifications and includes dead battery support, allowing it to function as a Sink even when no power is applied. The device is designed for ultra-low power operation with typical current consumption below 10 uA in various states.
Why Choose This Part
This controller offers 28V DC tolerance on critical pins like CC and VBUS DET, providing robust protection against shorts. Its tiny 1.6mm x 1.6mm X2QFN package and autonomous operation reduce both PCB footprint and the software overhead typically required for USB-C negotiation.
Applications
Key Specifications
Getting Started
Engineers can evaluate the device using the FUSB303GEVB evaluation board. Integration involves connecting the I2C interface to a host processor for status monitoring or using the GPIOs for simple autonomous hardware-based signaling.
