ADUM1251ARZ-RL7

ADUM1251 is a hot swappable digital isolator with nonlatching, bidirectional communication channels that are compatible with I²C interfaces. This eliminates the need for splitting I²C signals into separate transmit and receive signals for use with standalone optocouplers. This device provides one bidirectional channel and one unidirectional channel for applications where a bidirectional clock is not required. It contain hot swap circuitry to prevent glitching data when an unpowered card is inserted onto an active bus. It is approved by UL recognition, 2500V rms for 1 minute per UL 1577, CSA component acceptance notice 5A, VDE certificate of conformity, DIN V VDE V 0884-10 (VDE V 0884-10):2006-12, VIORM = 560V peak. It is widely used in application such as Isolated I²C, SMBus, or PMBus interfaces, multilevel I²C interfaces, power supplies, networking, power over Ethernet, hybrid electric vehicle battery management etc.
