TPS2541RTER

Product Summary

The TPS2541RTER is a combination of current-limited USB port power switch with a USB 2.0 high-speed data line (D+/D-) switch and a USB charging port identification circuit. Applications include notebook PCs and other intelligent USB host devices. The wide bandwidth (2.6 GHz) data-line switch also features low capacitance and low on resistance, allowing signals to pass with minimum edge and phase distortion. The TPS2541RTER monitors D+ and D-, providing the correct hand-shaking protocol with compliant client devices. The applications of the TPS2541RTER include USB Ports/Hubs, Notebook PCs, Universal Wall Charging Adapter.
