| USB251xB/USB251xBi USB 2.0 Hub Controllers. 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. Features. High performance, low-power, small footprint Hub Controller IC Fully compliant with the USB 2.0 Specification Supports the USB Battery Charging specification Rev. 1.1 for Charging Downstream Ports (CDP) Available with 2, 3 or 4 downstream ports MultiTRAK™ - Provides one high-performance transaction translator per port PortMap – Flexible port mapping and disable sequencing PortSwap – Programmable USB differential-pair pin locations to align USB signal lines directly to connectors PHYBoost - Programmable USB signal drive strength for recovering signal integrity Full power management with individual or ganged power control of each downstream port Drop-in replacement for USB251x/USB251xA devices More information: | | Number of Transceivers: | 2 | IC Type: | Transceiver IC | Protocols Supported: | USB 2.0 | Power Supply Type: | Single | ESD Protection: | Yes | Typical Single Supply Voltage: | 3 to 3.6 V | Mounting Type: | Surface Mount | Package Type: | SQFN | Pin Count: | 36 | Dimensions: | 6 x 6 x 0.9mm | Height: | 0.9mm | Length: | 6mm | Maximum Operating Temperature: | +85 °C | Minimum Operating Temperature: | -40 °C | Width: | 6.1mm |
