Description

The LTM2894 is a complete galvanically-isolated USB 2.0 compatible ?Module? (micromodule) transceiver.The LTM2894 is ideal for isolation in host, hub, bus splitter or peripheral device applications. It is compatible 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 ?Module technology uses coupled inductors to provide 7500VRMS of isolation and 17.4mm of creepage between the upstream and downstream USB interface. This device is ideal for systems requiring isolated ground returns or large common mode voltage variations. Uninterrupted communication is guaranteed for common mode transients greater than 50kV/?s.Enhanced ESD protection allows this part to withstand up to ?20kV (human body model) on the USB transceiver interface pins to local supplies and ?20kV through the isolation barrier to supplies without latch-up or damage.Applications Isolated USB Interfaces Host, Hub, or Device Isolation Industrial/Medical Data Acquisition
