This is desirable in many RoHS compliant cases because it minimizes external components and simplifies Safety and regulatory approvals (RI-16 package) the design however, this presents particular challenges when UL recognition: 5000 V rms for 1 minute per isolation is required. USB lines must automatically switch between UL 1577 actively driving D+/D, receiving data, and allowing external CSA Component Acceptance Notice 5A resistors to set the idle state of the bus. The ADuM4160 provides IEC 60601-1: 250 V rms (reinforced) mechanisms for detecting the direction of data flow and control IEC 60950-1: 400 V rms (reinforced) over the state of the output buffers. Data direction is determined VDE Certificate of Conformity on a packet-by-packet basis. DIN V VDE V 0884-10 (VDE V 0884-10):2006-12 The ADuM4160 uses the edge detection based iCoupler tech- V = 846 V peak IORM nology in conjunction with internal logic to implement a APPLICATIONS transparent, easily configured, upstream facing port isolator. Isolating an upstream facing port provides several advantages USB peripheral isolation in simplicity, power management, and robust operation. Isolated USB hub Medical applications The isolator has propagation delay comparable to that of a standard hub and cable. It operates with the bus voltage on GENERAL DESCRIPTION either side ranging from 4.5 V to 5.5 V, allowing connection 1 The ADuM4160 is a USB port isolator, based on Analog Devices, directly to V by internally regulating the voltage to the signaling BUS Inc., iCoupler technology. Combining high speed CMOS and level. The ADuM4160 provides isolated control of the pull-up monolithic air core transformer technology, these isolation resistor to allow the peripheral to control connection timing. components provide outstanding performance characteristics The device has a low idle current so a suspend mode is not and are easily integrated with low and full speed USB-compatible required. A 2.5 kV version, the ADuM3160, is also available. peripheral devices. 1 Protected by U.S. Patents 5,952,849 6,873,065 7,075,329. Rev.
