The ADuM2250/ADuM2251 are bidirectional I2C isolators, suitable for hot-swap applications, rated for 5 kV.
The ADuM2250 and ADuM2251 are hot‑swappable digital isolators that provide non‑latching bidirectional I2C communication channels. They integrate iCoupler transformer technology to deliver isolated I2C, SMBus, or PMBus interfaces in a compact 16‑lead SOIC package.
The devices support supply voltages from 3.0 V to 5.5 V, operate from –40 °C to +105 °C, and meet safety standards such as UL 1577 and IEC 60950‑1. They are suitable for power‑over‑Ethernet, networking, and multilevel I2C applications where isolation and hot‑swap capability are required.
