The 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. The recommended 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.
