General Description

The Microchip USB251xB/xBi hub is a family of lowpower,

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 lowspeed,

full-speed, and hi-speed (if operating as a hispeed

hub) downstream devices on all of the enabled

downstream ports.

Features

? USB251xB/xBi products are fully footprint compatible

with USB251x/xi/xA/xAi products as direct

drop-in replacements

— Cost savings include using the same PCB

components and application of USB-IF Compliance
