ADuM1251 Isolated I2C, SMBus, or PMBus interfaces Multilevel I2C interfaces Power supplies Networking Power-over-Ethernet Hybrid electric vehicle battery management GENERAL DESCRIPTION The ADuM1250/ADuM12511 are hot swappable digital isolators with nonlatching, bidirectional communication channels compatible with I2C® interfaces. This eliminates the need for splitting I2C signals into separate transmit and receive signals for use with standalone optocouplers. The ADuM1250 provides two bidirectional channels, supporting a complete isolated I2C interface. The ADuM1251 provides one bidirectional channel and one unidirectional channel for those applications where a bidirectional clock is not required. 1 Both the ADuM1250 and ADuM1251 contain hot swap circuitry to prevent glitching data 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 as compared to optocouplers. With the ADuM1250/ADuM1251, iCoupler channels can be integrated with semiconductor circuitry, which enables a complete isolated I2C interface to be implemented in a small form factor.
