, iCoupler® technology.
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.
Many microcontrollers implement USB so that it presents only the D+ and D− lines to external pins.
This is desirable in many cases because it minimizes external components and simplifies the design; however, this presents particular challenges when isolation is required.
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.
Data direction is determined on a packet-by-packet basis.
The ADuM3160 uses the edge detection based iCoupler technology in conjunction with internal logic to implement a transparent, easily configured, upstream-facing port isolator.
