LTM2884

Isolated USB Transceiver with Isolated Power

FEATURES

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.

LTM2884: 2500V

for 1 Minute

LTM2884(a): 3000V

LTM2884(a): CSA Recognized

USB 2.0 Full Speed and Low Speed Compatible

Integrated Isolated DC/DC Converter, External or

Bus Powered

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 inte-

grated pull-up resistors on the upstream port to match

those sensed on the downstream device.

Auto-Configuration of Bus Speed

2.5W (500mA at 5V) Output Power from External

Input Supply (V = 8.6V to 16.5V)

1W (200mA at 5V) Output Power from USB Bus

The isolator µModule technology uses coupled induc-

tors and an isolated power transformer to provide isola-

tion between the upstream and downstream USB inter-

face. 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.

High Common Mode Transient Immunity: 30kV/μs

ESD: 15kV HBM on USB Interface Pins

APPLICATIONS

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.
