Full/Low Speed 2.5 kV USB Digital Isolator Data Sheet ADuM3160 FEATURES GENERAL DESCRIPTION 1 USB 2.0 compatible The ADuM3160 is a USB port isolator based on Analog Low and full speed data rate: 1.5 Mbps and 12 Mbps Devices, Inc., iCoupler technology. Combining high speed CMOS Bidirectional communication and monolithic air core transformer technology, this isolation 4.5 V to 5.5 V V operation BUS component provides outstanding performance characteristics 7 mA maximum upstream supply current at 1.5 Mbps and is easily integrated with low and full speed USB-compatible 8 mA maximum upstream supply current at 12 Mbps peripheral devices. 2.3 mA maximum upstream idle current Many microcontrollers implement USB so that it presents only the Upstream short-circuit protection D+ and D lines to external pins. This is desirable in many cases Class 3A contact ESD performance per ANSI/ESD STM5.1-2007 because it minimizes external components and simplifies the High temperature operation: 105C design however, this presents particular challenges when isolation High common-mode transient immunity: >25 kV/s is required. Because the USB lines must switch between actively 16-lead SOIC wide body package driving D+/D and allowing external resistors to set the state of RoHS compliant the bus, the ADuM3160 provides mechanisms for detecting the Qualified for automotive applications direction of data flow and control over the state of the output Safety and regulatory approvals buffers. Data direction is determined on a packet-by-packet basis. UL recognition: 2500 V rms for 1 minute per UL 1577 The ADuM3160 uses the edge detection based iCoupler CSA Component Acceptance Notice 5A technology in conjunction with internal logic to implement IEC 60950-1: 600 V rms (basic) a transparent, easily configured, upstream-facing port isolator. VDE certificate of conformity Isolating the upstream port provides several advantages in DIN V VDE V 0884-10 (VDE V 0884-10):2006-12 simplicity, power management, and robust operation. V = 560 V peak IORM The isolator has a propagation delay comparable to that of a APPLICATIONS standard hub and cable. It operates with the bus voltage on either USB peripheral isolation side ranging from 4.5 V to 5.5 V, allowing connection directly to Isolated USB hub VBUSx by internally regulating the voltage to the signaling level. The ADuM3160 provides isolated control of the pull-up resistor to allow the peripheral to control connection timing. The device draws low enough idle current that a suspend state is not required. A 5 kV, reinforced insulation version, the ADuM4160, is available.
