The EMS4000 is a bidirectional low-power dual port, high-speed, USB 2.0 analog switch with integrated protection for USB Type-C™ systems. The device is configured as a dual 2:1 or 1:2 switch. It is optimized for use with the USB 2.0 DP/DM lines in a USB Type-C™ system.
The device integrates over-voltage protection on the C0+/- pins can withstand up to DC 30V with automatic shutoff circuitry in order to protect system components behind the switch. GPIO controls of SEL and EN are 1.8V logic compatible.
The EMS4000 is available in QFN 1.4x1.8-10L and QFN 1.5x2.0-10L package with Pb-free and Halogen-free making it a perfect candidate for mobile and space constrained applications.
