5000Vrms isolation in a 2-channel unidirectional isolator
The ADI ADUM2201BRWZ is a 2-channel general-purpose digital isolator from the iCoupler family, using magnetic coupling to deliver 5000Vrms isolation in a 16-SOIC package. The unidirectional channel configuration (one input on side 1, one on side 2) suits applications that need a single isolation barrier between two logic domains.
What the 25kV/µs CMTI buys the design
With a minimum common-mode transient immunity of 25kV/µs, this isolator handles the fast switching edges from IGBTs or SiC MOSFETs in motor drives and inverters without data corruption. The 50ns max propagation delay and 3ns pulse-width distortion keep timing margins tight for synchronous interfaces.
Operating from 3V to 5.5V on either side, the ADUM2201BRWZ directly bridges 3.3V and 5V logic without external level translation. The 2.5ns typical rise/fall times preserve signal integrity across the barrier at 10Mbps.
For dual-sourcing or supply-chain resilience, the ADUM2200BRWZ (2/0 input configuration) shares the same package, data rate, and isolation rating, differing only in channel direction.
