Simplify Your USB Type-C Designs With Solutions From Fairchild

USB Type-C seeks to free users from searching for cables and fiddling connectors in ports the right way round. The latest USB interface combines the small size of micro-USB Type-B plugs with increased performance, faster data transfer and higher power charging.

Fairchild released a range of new components in order to help designers to manage the transition towards the new standard as smoothly as possible. The portfolio includes discrete, flexible USB Type-C solutions from controllers to power switches and SuperSpeed switches.

Smaller, Lighter & More Powerful

As a rule of thumb, as end users, we all want our devices to be small, have long battery life, to be easy to use and to be affordable. Fairchild has taken those end-customer desires into account and created USB Type-C components which are optimised for cost, footprint and low-power use with power consumption being 1/20 of the nearest competitive solution and packages up to 95% smaller.
The portfolio covers Dual Role Port (DRP), Downstream Facing Port (DFP) and Upstream Facing Port (UFP) implementations and accessory detection while providing software flexibility for 
multi-platform support.

The controllers communicate through I2C which allows for reuse of an existing microprocessor and provides flexibility to reflect any future specification changes in software.

The Fairchild power switches support the Type-C VBUS requirements for various charging levels along with competitive RDSON and selectable protection features. The available SuperSpeed switches offer USB 3.1 capabilities in combination with the smallest possible footprint.

Flexible Solutions For The Future Of USB

As USB standards are constantly evolving it is necessary to find solutions which allow you to upgrade your devices along with the specification updates and changes. With the FUSB302 family of controllers Fairchild has created such a solution.

In order to eliminate the impact of upgrades on the whole system the FUSB302 controllers are designed to be the Type-C and PD interface between the current system and the new Type-C connector. Thus the Type-C/PD system architecture has been split into two separate components, hardware and software.

As you can see Fairchild has integrated everything developers need in order to implement a Type-C design, including the Pull up (Rp), Pull down (Rd) and Vconn switches to fully support the Type-C specification on the hardware side. Furthermore, PD applications are supported due to the BMC transmitter and receiver which are part of the FUSB302.

This solution offers an incredible level of flexibility to designers who are now able to easily update the firmware on devices to the latest specifications without working on both, the the system and PD controller sides. The benefits of this simplified approach are also reflected in reduced engineering time and hardware costs.
