A 5 kV, reinforced insulation version, the ADuM4160, is available. The device draws low enough idle current that a suspend state is not required. If you want to stay on the save side, use a active USB hub when your device needs more than. This is because of the efficiency of the built-in DC/DC converter. The ADuM3160 provides isolated control of the pull-up resistor to allow the peripheral to control connection timing. Although the built-in DC/DC converter of the USB ISOLATOR can supply up to 580 mA, only 360 mA current output to the connected USB device is allowed to stay inside the USB specification. It operates with the bus voltage on either side ranging from 4.5 V to 5.5 V, allowing connection directly to VBUSx by internally regulating the voltage to the signaling level. The isolator has a propagation delay comparable to that of a standard hub and cable. Isolating the upstream port provides several advantages in simplicity, power management, and robust operation. The ADuM3160 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. Because the USB lines must switch between actively driving D+/D− and allowing external resistors to set the state of the bus, the ADuM3160 provides mechanisms for detecting the direction of data flow and control over the state of the output buffers.

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, this isolation component provides outstanding performance characteristics and is easily integrated with low and full speed USB-compatible peripheral devices. The ADuM3160 is a USB port isolator based on Analog Devices, Inc., iCoupler® technology. Impulse can supply the ISO-1R on its own or configured as part of a system.įor more information about the ISO-1R and our system integration services please contact our technical sales team on +44 (0)1782 337 800 or alternatively submit an enquiry.ADuM3160 USB Digital Isolator Full/Low Speed 2.5 kV Analog Devices’ features their ADuM3160 isolators with iCoupler® technology for general multichannel isolation If you need a ruggedized USB isolator cable, see the ISO-1R. If you need a USB isolator with removable cables, see the ISO-1. A variety of USB cables are available as accessories. Standard operating temperature range is -20C to +60C and extended temperature ranges are optional. The printed circuit board includes M2 x 4mm threaded standoffs to simplify mounting in your application. The ISO-1-OEM is a USB 2.0 compatible device connecting to the host over a high-speed link and features full-speed (12 Mbps) data rates between the downstream USB device.

The isolator is easy to install and is automatically recognised as a generic USB hub device. Supported in Microsoft Windows, Linux, and other USB aware operating systems, the ISO-1-OEM requires no separate drivers. Convenient high-retention USB connectors prevent accidental cable disconnections. Additionally, the isolator can provide a full 500 mA to a downstream device when connected to a USB port capable of sourcing 1 A, or greater. The isolator provides up to 300 mA to a downstream USB device when connected to a standard 500 mA USB port. The ISO-1-OEM is USB bus powered and the efficient DC/DC design allows energy transfer over the isolation barrier. The ISO-1-OEM is UL Recognised, in accordance with EN60601-1 3rd Edition, and protects both the data and power lines with 4 kV of medical-grade optical isolation between the host control system and connected USB equipment.

The OEM single-port, inline USB isolator offers a simple method of protecting host and field equipment from damaging transients and surges commonly found in commercial, industrial and medical environments. For applications that require embedded USB isolation, the SeaISO ISO-1-OEM is the ideal solution.
