GENERAL DESCRIPTION

The ADuM41601 is a USB port isolator, based on Analog Devices,

Inc., iCoupler? technology. Combining high speed CMOS and

monolithic air core transformer technology, these isolation

components provide outstanding performance characteristics

and are easily integrated with low and full speed USB-compatible

peripheral devices.

Many microcontrollers implement USB so that it presents only

the D+ and D? lines to external pins. This is desirable in many

cases because it minimizes external components and simplifies

the design; however, this presents particular challenges when

isolation is required. USB lines must automatically switch between

actively driving D+/D?, receiving data, and allowing external

resistors to set the idle state of the bus. The ADuM4160 provides

mechanisms for detecting the direction of data flow and control

over the state of the output buffers. Data direction is determined

on a packet-by-packet basis.

The ADuM4160 uses the edge detection based iCoupler technology

in conjunction with internal logic to implement a

transparent, easily configured, upstream facing port isolator.

Isolating an upstream facing port provides several advantages

in simplicity, power management, and robust operation.

The isolator has propagation delay comparable to that of a

standard hub and cable. It operates with the bus voltage on

either side ranging from 4.5 V to 5.5 V, allowing connection

directly to VBUS by internally regulating the voltage to the signaling

level. The ADuM4160 provides isolated control of the pull-up

resistor to allow the peripheral to control connection timing.

The device has a low idle current; so a suspend mode is not

required. A 2.5 kV version, the ADuM3160, is also available.
