A 5 kV, reinforced insulation version, the ADuM4160, is available. The ADuM3160 provides isolated control of the pull-up resistor to allow the peripheral to control connection timing. It operates with the supply voltage on either side ranging from 3.0 V to 5.5 V, allowing connection directly to V BUSx by internally regulating the voltage to the signaling level. The isolator has 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.
