The ADUM2250 series hot swappable Digital Isolators with non-latching, bidirectional communication channels. It is compatible with I2C interfaces. This eliminates the need for splitting I2C signals into separate transmit and receive signals for use with standalone optocouplers. The ADuM2250 provides two bidirectional channels, supporting a complete isolated I2C interface. It contains hot swap circuitry to prevent data glitches when an unpowered card is inserted onto an active bus. It is based on iCoupler? chip scale transformer technology from Analog Devices, Inc. iCoupler is a magnetic isolation technology with performance, size, power consumption and functional advantages compared to optocouplers. It integrates iCoupler channels with semiconductor circuitry to enable a complete, isolated I2C interface in a small form factor package.
