The USB Implementer Forum (IF) recently released updates to the USB Type-C, USB Type-C Cable and Connector, and USB Power Delivery specifications. The updates resolve known issues and add important new features, including support for new IEC power supplies. Unlike other USB Type-C controllers, the Fairchild FUSB302 family was designed for use with existing microprocessors via the I2C protocol. This flexibility allows changes to the various USB Type-C specifications to be easily supported via firmware rather than hardware.
“Our FUSB302 line of USB Type-C controllers addresses manufacturers’ concerns over updates to the specifications, so they can easily add the next generation of USB functionality to their smartphones, tablets, PCs and other mobile devices,” says Myron Miske, Interface and Protection Product Line Director at Fairchild. “The FUSB302’s combination of small size, low power consumption and ‘investment protection’ advantages have made it a popular solution used in many products shipping today.”
The new FUSB302B is the latest addition to the FUSB302 family. It is the smallest USB Type-C controller with PD capability currently available, measuring a mere 1.2 mm x 1.3 mm in a 9-ball WLCSP package. Its small size is complimented by its ultra-low power consumption of 25µA, a critical advantage for battery-powered devices. FUSB302B also supports data role swap, power role swap, hard reset, soft reset, active cables and vendor defined messages (VDM) packet transmission.
