General Description
Renesas SLG55546 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
SLG55546 monitors D+ and D-, providing the correct
hand-shaking protocol with compliant client devices.
