iCoupler® USB Isolation – Industry's First Single Package Solution
iCoupler® USB Isolation Industry's First Single Package Solution
The recently announced ADuM4160 is the industry's first single package USB isolation solution. Based on Analog Devices proprietary iCoupler technology which employs chip-scale micro-transformers, the USB 2.0 compliant ADuM4160 is fully isolated to 1.5-Mbps and 12-Mbps data rates and has been developed to lower system cost, reduce design size, and to lessen design time all while meeting the most demanding medical and industrial standards.
The ADuM4160 offers 5kV rms medical-grade isolation with IEC 60601-1 medical safety approvals pending. The isolation provided by the ADuM4160 will electrically isolate patients and equipment protecting them from harmful surges or spikes. The isolation also eliminates the need to disconnect during defibrillation.
ADuM4160 and Industrial Applications
The ADuM4160 electrically isolates instrumentation and controls by protecting equipment from damaging surges or spikes and by eliminating down time when using non-isolated ports. The USB isolator requires safety certifications (i.e., UL, CSA, VDE) to prove protection capability. USB improves industrial and instrumentation solutions by making it easier, faster, and more flexible for staff to work with sensors, controls, equipment, and systems.
ADuM4160 Reduces Cost, Complexity, and Components When Compared to Existing Methods of Isolation
Only a small portion of USB ports in medical, industrial, and instrumentation systems are isolated today due to the complexity, cost, and number of components associated with isolating USB. The ADuM4160 simplifies designs, decreases solution size, and in turn reduces costs significantly. As demonstrated below, when compared to the current methods of isolation, the ADuM4160 single package solution easily fits within a system by direct D+/D- isolation.
Isolated power is needed on either side of the isolation barrier in USB applications. Each side can provide its own power. For example, a patient monitor is plugged into the wall, and a laptop is powered by it's own battery. Another way to achieve power on either side of the isolation barrier is for the system to use an isolated DC/DC converter. Designers can use the ADuM5000 � W isolated power supply, or another source to provide power. The ADuM4160 evaluation board includes the ADuM5000 to provide isolated power.
