FUSB303TMX

Controllers Overview

The FUSB303TMX is a USB Type-C port controller manufactured by onsemi, designed for applications requiring 15 W or less. It operates within a voltage range of 2.85 V to 5.5 V and supports Full Speed data rates. The device features ultra-low power consumption with an operating current of 10 uA and functions across temperatures from -40°C to +85°C. Packaged in a QFN-12 format, it complies with USB-C 1.0 standards and utilizes an I2C interface for configuration.

Controllers Feature Summary

• Fully autonomous USB Type-C port controller supporting source, sink, and dual-role port configurations
• Includes accessory detection support and dead battery functionality for sink ports without applied power
• Configurable via I2C interface or hardware pins to accommodate multiple ports per system

Controllers Applications

• Evaluation of Type-C interface detection solutions using dedicated GUI software
• Configuration as standalone source, sink, or DRP devices with power supply connections
• Integration into systems requiring configurable I2C addresses for multi-port architectures

Controllers Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance documentation availability prior to procurement. Ensure storage conditions align with manufacturer specifications to maintain integrity. Validate package markings against official datasheet references to prevent counterfeit substitution during acquisition.

Controllers Selection Notes
