The FUSB302UCX is an advanced, high-speed and low-power USB Type-C port controller designed by Fairchild Semiconductor. It is primarily used in USB Type-C applications with Type-A to Type-C connections. It is part of the FUSB302 family of Type-C controllers.

The FUSB302UCX provides a number of features that make it an attractive solution for USB Type-C applications. It offers ultra-low power operation (as low as 10µA), support for USB Type-C Alternate Modes, optimized EMI and ESD protection as well as USB power delivery. It supports up to USB 3.1 Gen 1 (5Gbps) data rate, compatible with USB2.0, USB Battery Charging and USB Audio. It also integrates a micro-controller unit (MCU) which provides system intelligence and I/O control.

The FUSB302UCX is optimized for use in a wide range of applications, including cellular handsets, tablets, ultrabooks, and other mobile devices. Its MCU can be used to control the power delivery, offering up to 100W of power to USB peripheral devices. It also supports capless connectors, which improves space optimization and design flexibility in light and thin applications. Additionally, the MCU also provides support for Type-C audio and displays protocols.

The working principle of the FUSB302UCX is based on the USB Type-C protocol. It utilizes the USB Type-C parallel detection and type-c reverse data path architectures, in order to switch between the Type-C roles of source and sink. This enables the use of up to 100W of power delivery over the Type-C cable. It also contains a large library of configurable functions, allowing it to be used in different configurations.

The FUSB302UCX implements the USB Type-C protocol at the PHY, Link and protocol layers. This integrated solution supports multi-speed (5Gbps, 10Gbps and 20Gbps) USB data rates and USB Battery Charging v1.2, offering up to 100W of power delivery. Its advanced power delivery protection ensures safe and reliable operation, even in extreme conditions.

The FUSB302UCX has an intelligent system that monitors the charging ports for various events such as over-voltage and over-current conditions, as well as over-temperature changes. Additionally, it supports many control and status signals, allowing it to integrate with a range of other system components, including power supplies and other peripherals.

The FUSB302UCX is highly flexible and configurable and can be used in a variety of applications. It is ideal for mobile device designs, offering a high level of integration, low power requirements and compatibility with USB Type-C protocols. This allows designers to create a variety of applications within a single FUSB302UCX device.
