LTM2884
Isolated USB Transceiver
with Isolated Power
Description
The LTM®2884 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 split-
ter 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 2500VRMS
of 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.
