The SLGC55545 is a combination of a 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 (2.6GHz) data-line switch also features low capacitance and low ON resistance, allowing signals to pass with minimum edge and phase distortion. The SLGC55545 monitors D+ and D-, providing the correct hand-shaking protocol with compliant client devices.
