Smallest USB Type-C Controller with PD


Fairchild claims the smallest USB Type-C controller with PD capability, measuring a mere 1.2 mm x 1.3 mm in a 9-ball WLCSP package. It is the latest addition to the FUSB302 line of USB Type-C controllers, which the firm says, 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.

The FUSB302 series is said to be the industry’s first to be compatible with the latest 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 FUSB302 can work 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.

“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”, said Myron Miske, Interface and Protection Product Line Director at Fairchild.


The FUSB302’s 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.
