The LTM2884 is a complete galvanically isolated USB 2.0 compatible μModule®(micromodule) transceiver. 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 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 μModule technology uses coupled inductors and an isolated power transformer to provide isolation 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 30kV/μs.Enhanced ESD protection allows this part to withstand up to ±15kV (human body model) on the USB transceiver interface pins to local supplies and ±15kV through the isolation barrier to supplies without latch-up or damage.ApplicationsIsolated USB InterfacesHost, Hub, or Device IsolationIndustrial/Medical Data Acquisition
