About UsFairchild Releases New USB Type-C Portfolio
New Range of USB Type-C Solutions Offer a Wide Range of Options for Interfacing and Control
Fairchild has launched a comprehensive portfolio of USB Type-C solutions that enable manufacturers to quickly and easily add the next generation of USB functionality to smartphones, computers, power adapters and other devices with a USB port. Compared to alternatives, the smaller size and lower power requirements of Fairchild’s USB Type-C solutions help manufacturers to develop thinner, sleeker devices that consume less system power for better energy efficiency.
“Relative to competing solutions that can consume up to 10x more power, Fairchild’s USB Type-C solutions portfolio leads the industry in both low power consumption and small size, two critical requirements in today’s increasingly small and thin battery-powered devices,” said Jin Zhao, Sr. Director, Product Line Business Management at Fairchild. “Manufacturers are already taking advantage of Fairchild’s USB Type-C solutions to ship products that meet the new standard, including the maker of the world's first USB Type-C smartphone.”
Fairchild’s USB Type-C solutions meet a wide variety of application requirements to give manufacturers more choice and flexibility in selecting the device with the best mix of capabilities for their product. Several of Fairchild’s USB Type-C solutions perform basic features such as detect attachment, orientation and device type (Dual Role Port, Downstream Facing Port, and Upstream Facing Port), while others support more advanced functionality. These advanced functions include data role swap, power role swap, hard reset, soft reset, active cable support, Vendor Defined Messaging (VDM) packet transmission and high power charging up to 100W.
The new USB Type-C solutions are easier to integrate into product designs thanks to their small footprint In particular, the FUSB302 comes in a miniscule 1.2 mm x 1.3 mm WLCSP package, which is several times smaller than competing offerings, to give manufacturers more flexibility in their size constrained designs.
Fairchild’s USB Type-C solutions use an I2C interface to communicate with the application's host processor for control and command, negating the need for an integrated microprocessor.
This system partitioning enables Fairchild to offer the lowest-power, as well as the smallest size, and flexibility.
