Part Details:

Hot-Swappable, Dual I2C Isolators, 5 kV ADuM2250/ADuM2251 FEATURES GENERAL DESCRIPTION Bidirectional I2C communication The ADuM2250/ADuM22511 are hot-swappable digital Open-drain interfaces isolators with nonlatching bidirectional communication Suitable for hot-swap applications channels that are compatible with I2C® interfaces. This 30 mA current sink capability eliminates the need for splitting I2C signals into separate 1000 kHz operation transmit and receive signals for use with standalone 3.0 V to 5.5 V supply/logic levels optocouplers. Wide body, 16-lead SOIC package with >8 mm creepage The ADuM2250 provides two bidirectional channels support- High temperature operation: 105°C ing a complete isolated I2C interface. The ADuM2251 provides Safety and regulatory approvals one bidirectional channel and one unidirectional channel for UL recognition (pending) those applications where a bidirectional clock is not required. 5000 V rms for 1 minute per UL 1577 CSA Component Acceptance Notice #5A The ADuM2250/ADuM2251 contain hot-swap circuitry to VDE Certificate of Conformity prevent data glitches when an unpowered card is inserted DIN V VDE V 0884-10 (VDE V 0884-10): 2006-12 onto an active bus. VIORM = 846 V peak These isolators are based on iCoupler® chip-scale transformer APPLICATIONS technology from Analog Devices, Inc. iCoupler is a magnetic isolation technology with performance, size, power consump- Isolated I2C, SMBus, or PMBus Interfaces tion, and functional advantages compared to optocouplers. Multilevel I2C interfaces The ADuM2250/ADuM2251 integrate iCoupler channels Power supplies with semiconductor circuitry to enable a complete, isolated Networking I2C interface in a small form-factor package.
