ADUM2250

Hot-Swappable Dual I2C® Isolators, 5 kV
Manufactured by:

Product Details

The ADuM2250/ADuM2251 are hot swappable digital isolators with nonlatching bidirectional communication channels and are compatible with I2C interfaces. This eliminates the need for splitting I2C signals into separate transmit and receive signals for use with stand-alone optocouplers.

The ADuM2250 provides two bidirectional channels supporting a complete isolated I2C interface. The ADuM2251 provides one bidirectional channel and one unidirectional channel for those applications where a bidirectional clock is not required.

The ADuM2250/ADuM2251 contain hot swap circuitry to prevent data glitches when an unpowered card is inserted onto an active bus.

These isolators are based on iCoupler® chip-scale transformer technology from Analog Devices, Inc. iCoupler is a magnetic isolation technology with functional, performance, size, and power consumption advantages compared to optocouplers. The ADuM2250/ADuM2251 integrate iCoupler channels with semiconductor circuitry to enable a complete, isolated I2C interface provided in a small form-factor.

Applications
  • Isolated I2C, SMbus, or PMBus Interfaces
  • Multilevel I2C interfaces
  • Power supplies
  • Networking
  • Power-over-Ethernet

Product Details

The ezLINX™ iCoupler® Isolated Interface Development Environment provides developers with a cost-effective, plug and play method for evaluation eight physical layer, digitally-isolated communication standards (USB, RS-422, RS-485, RS-232, CAN, SPI, I2C, and LVDS). The Blackfin® ADSP-BF548 processor is used to run the uCLinux operating system and allows for easy customization through the open source hardware and software platform. Development time is significantly reduced for embedded designers and system architects who are designing and evaluating isolated communication standards. The interfaces on ezLINX use ADI's isolated transceivers with integrated iCoupler® and isoPower® digital isolator technology.

Pretty Good I2C Isolator
The IC works good as an I2C Isolator but there are many pins which are NC, instead if the footprint of the IC could be reduced then it could have been great.
