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.

APPLICATIONS

• Isolated I²C, SMBus, or PMBus interfaces
• Multilevel I²C interfaces
• Power supplies
• Networking
• Power over Ethernet
• Hybrid electric vehicle battery management
