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 V

by internally regulating the voltage to the signaling

BUS

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.
