General Description

Renesas SLG55544 is a combination of current-limited USB

port power switch with a USB 2.0 high-speed data line

(D+/D-) switch and 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

SLG55544 monitors D+ and D-, providing the correct

hand-shaking protocol with compliant client devices.
