ADUM1251WARZ-RL7

ADUM1251WARZ-RL7 is a hot-swappable digital isolator with non-latching, bidirectional communication channels that are compatible with I²C interfaces. It 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 contains hot swap circuitry to prevent glitching data when an unpowered card is inserted onto an active bus. It is approved by DIN VDE V 0884-11:2017-01, reinforced VIORM = 560V peak, 2500V rms for 1 minute per UL 1577, IEC/EN/CSA 62368-1, IEC/CSA 61010-1, CAN/CSA-C22.2 No. 14-18, GB4943.1-2011. It is used in applications such as isolated I²C, SMBus, or PMBus interfaces, multilevel I²C interfaces, power supplies, networking, power over ethernet, hybrid electric vehicle battery management.
