USB2.0高速切换开关芯片FSW7227简介替代SGM7227

DESCRIPTION

The FSW7227 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 opti-

mized for use with the USB 2.0 DP/DM lines in a

USB Type-C™ system.

The FSW7227 integrated 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 FSW7227 is available in UQFN 1.4x.18-10L

and MSOP10 with Pb-free and Halogen-free mak

ing it a perfect candidate for mobile and space

constrained applications.
