The device has a low idle current a suspend mode is not required. The ADuM4160 provides isolated control of the pull-up resistor to allow the peripheral to control connection timing. It operates with the supply voltage on either side ranging from 3.1 V to 5.5 V, allowing connection directly to VBUS by internally regulating the voltage to the signaling level. The isolator has propagation delay comparable to that of a standard hub and cable. Isolating an upstream facing port provides several advantages in simplicity, power management, and robust operation. The ADuM4160 uses the edge detection based iCoupler technology in conjunction with internal logic to implement a transparent, easily configured, upstream facing port isolator. Data direction is determined on a packet-by-packet basis. The ADuM4160 provides mechanisms for detecting the direction of data flow and control over the state of the output buffers.

USB lines must automatically switch between actively driving D+/D−, receiving data, and allowing external resistors to set the idle state of the bus. This is desirable in many cases because it minimizes external components and simplifies the design however, this presents particular challenges when isolation is required. Many microcontrollers implement USB so that it presents only the D+ and D− lines to external pins.

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. The ADuM4160 is a USB port isolator, based on Analog Devices, Inc., iCoupler® technology. ADUM4160 Full/Low Speed USB Digital Isolator
