USB 2.0 Hi Speed Hub Controller 48-Pin QFN EP T/R

The Microchip USB2514 hub is a family of lowpower, configurable, MTT (multi transaction translator) hub controller IC products for embedded USB solutions. The 4 in the part number indicates the number of downstream ports available, while the B indicates battery charging support. The Microchip hub supports low-speed, full-speed, and hi-speed (if operating as a hispeed hub) downstream devices on all of the enabled downstream ports.
