USB 2.0 hub controller in a 48-SQFN package
The Microchip USB4715T-I/Y9X is a USB 2.0 hub controller that handles the bus negotiation and port management for downstream USB devices. The 48-VFQFN exposed-pad package (7x7 mm SQFN) provides a low-inductance ground path through the central thermal pad, which is critical for signal integrity on the USB differential pairs.
Packaging options include Tape & Reel for automated pick-and-place and Cut Tape for prototype or low-volume builds. The reel quantity is the production standard; cut tape is a distributor service for engineering samples.
What the supply voltage and temperature grade mean for your BOM
Routing the high-speed USB differential pairs out of the package calls for controlled-impedance traces and a solid ground pour on the layer directly below the pad.
