Overview

The SLGC55546C 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 SLGC55546C monitors D+ and D-, providing the correct hand-shaking protocol with compliant client devices.
