Controllers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and temperature grade. Ensure the component matches the required pinout and configuration options for the target embedded design before finalizing procurement.

Controllers Selection Notes

Select this model when a two-port USB 2.0 solution with battery charging capability is required. The 'Bi' designation indicates industrial temperature range suitability (-40°C to +85°C). Verify compatibility with existing PCB layouts as it is footprint compatible with commercial variants.

Controllers Part Context

This component belongs to the USB251xB/xBi family of low-power, configurable MTT hub controllers. The '2' in the part number specifies two downstream ports, while 'B' denotes battery charging support. It serves as a direct drop-in replacement for non-battery charging variants within the same footprint.

Controllers FAQ

How does the MultiTRAK technology benefit mixed-speed USB environments?

It implements a dedicated Transaction Translator (TT) for each port, helping maintain consistent full-speed data throughput regardless of the number of active downstream connections.

What is the function of the PortSwap feature?

PortSwap allows programmable USB differential-pair pin locations, easing PCB design by aligning USB signal lines directly to connectors to avoid uneven trace lengths or crossing.

Does the USB2512BI support self-powered operation?

Yes, the hub supports both self-powered and bus-powered operation modes.
