USB type-C controller supports power delivery specification
Claimed to be the first USB Type-C controllers compatible with the latest updates to the USB Type-C standard, the FUSB302 family enables manufacturers to support current and previous versions of the USB specifications in products.
The USB Implementer Forum (IF) recently released updates to the USB Type-C, USB Type-C Cable and Connector, and USB Power Delivery specifications. These controllers are designed for use with existing microprocessors via the I²C protocol. This allows changes to the various USB Type-C specifications to be easily supported via firmware rather than hardware in smartphones, tablets, PCs and other mobile devices.
The addition to the FUSB302 family is the smallest USB Type-C controller with PD capability currently available, says the company. It measures 1.2 x 1.3mm in a nine-ball WLCSP. Power consumption is just 25microA. It also supports data role swap, power role swap, hard reset, soft reset, active cables and vendor defined messages packet transmission.
