General Description

The Microchip USB251xB/xBi hub is a family of low-power, configurable, MTT (multi transaction translator) hub controller IC products for embedded USB solutions. The x 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 hi-speed hub) downstream devices on all of the enabled downstream ports.
