An upstream supply powers both sides of the interface through an integrated, isolated DC/DC converter. The LTM2884 is ideal for isolation in host, hub, bus splitter or peripheral device applications. It is patible with USB 2.0 full speed (12Mbps) and low speed (1.5Mbps) operation. Automatic speed selection configures integrated pull-up resistors on the upstream port to match those sensed on the downstream device. The isolator µModule technology uses coupled inductors and an isolated power transformer to provide 2500VRMS of isolation between the upstream and downstream USB interface. This device is ideal for systems requiring isolated ground returns or large mon mode voltage variations. Uninterrupted munication is guaranteed for mon mode transients greater than 30k V/μs. Enhanced ESD protection allows this part to withstand up to ±15k V (human body model) on the USB transceiver interface pins to local supplies and ±15k V through the isolation barrier to supplies without latch-up or damage.
