Part Details:

Full/Low Speed USB Digital Isolator Preliminary Technical Data ADuM4160 FEATURES isolation components provide outstanding performance characteristics and are easily integrated with low and full speed USB 2.0 compatible USB compatible peripheral devices. Enhanced system-level ESD performance per IEC 61000-4-x 4.0 V to 5.5V operation Many microcontrollers implement USB so that it presents only 7 mA maximum up-stream supply current @ 1.5 Mbps the D+ and D- lines to external pins. This is desirable in many 8 mA maximum up-stream supply current @ 12 Mbps cases because it minimizes external components and simplifies 2.5mA up-stream idle current the design; however, this presents particular challenges when Bidirectional communication isolation is required. Since the USB lines must switch between Up Stream Short Circuit Protection actively driving D+/D- and allowing external resistors to set the High temperature operation: 105°C state of the bus, the ADuM4160 provides mechanisms for Low and Full Speed data rate: 1.5Mbps and 12 Mbps detecting the direction of data flow and control over state of the High common-mode transient immunity: >25 kV/s output buffers. Data direction is determined on a packet by 16-lead SOIC wide body package packet basis. RoHS compliant models available The ADuM4160 uses the edge detection based iCoupler Safety and regulatory approvals (Pending) technology in conjunction with internal logic to implement a UL recognition: 5000 V rms for 1 minute per UL 1577 transparent, easily configured, up-stream facing port isolator. CSA Component Acceptance Notice #5A Isolating the up-stream port provides several advantages in IEC 60601-1: 250 V rms (reinforced) simplicity, power management and robust operation. IEC 60950-1: 600 V rms (reinforced) VDE certificate of conformity The isolator has propagation delay comparable that of a DIN V VDE V 0884-10 (VDE V 0884-10):2006-12 standard hub and cable. It operates with the supply voltage on V either side ranging from 3.0 V to 5.5 V, allowing connection IORM = 846 V peak directly to VBUS by internally regulating the voltage to the APPLICATIONS signaling level. The ADuM4160 provides isolated control of the USB peripheral isolation pull-up resistor to allow the peripheral to control connection
