Overview

The Microchip USB251xB/USB251xBi family of devices are USB 2.0 Hub Controllers. These devices feature MultiTRAK™ technology that incorporates a dedicated Transaction Translator (TT) per port to maintain consistent Full-Speed data throughput regardless of the number of active downstream connections.USB251xB/USB251xBi devices are fully customisable, helping to simplify PCB layout. PortMap, PortSwap and PHYBoost features all contribute to the flexibility of these devices.Hi-Speed (480 Mbps), Full-Speed (12 Mbps) and Low-Speed (1.5 Mbps) USB communications and USB Battery Charging (Rev. 1.1) are supported on all downstream ports.

High performance, low-power, small footprint Hub Controller ICFully compliant with the USB 2.0 SpecificationSupports the USB Battery Charging specification Rev. 1.1 for Charging Downstream Ports (CDP)Available with 2, 3 or 4 downstream portsMultiTRAK™ - Provides one high-performance transaction translator per portPortMap – Flexible port mapping and disable sequencingPortSwap – Programmable USB differential-pair pin locations to align USB signal lines directly to connectorsPHYBoost - Programmable USB signal drive strength for recovering signal integrityFull power management with individual or ganged power control of each downstream portDrop-in replacement for USB251x/USB251xA devices
