D Information furnished by Analog Devices is believed to be accurate and reliable. A 2.5 kv version, the ADuM360, is also available Protected by U.S. The device has a low idle current so a suspend mode is not required. The ADuM460 provides isolated control of the pull-up resistor to allow the peripheral to control connection timing. It operates with the bus voltage on either side ranging from 4.5 V to 5.5 V, allowing connection directly to VBUS by internally regulating the voltage to the signaling level. The isolator has propagation delay comparable to that of a standard hub and cable. Isolating an upstream facing port provides several advantages in simplicity, power management, and robust operation. The ADuM460 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. The ADuM460 provides mechanisms for detecting the direction of data flow and control over the state of the output buffers. USB lines must automatically switch between actively driving D+/D, receiving data, and allowing external resistors to set the idle state of the bus. 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.
