The ADUM2200BRWZ-RL is a 2-channel, unidirectional digital isolator from the iCoupler family, built with magnetic coupling technology. It provides 5000 Vrms galvanic isolation between the input and output sides, which is the key spec for meeting safety standards in industrial motor drives, medical equipment, and isolated power supplies. The 10 Mbps data rate covers most SPI, UART, and general-purpose GPIO isolation needs without forcing a higher-speed (and higher-cost) part into the BOM.
25 kV/µs CMTI — why it matters for motor drives and inverters
That figure directly determines whether the isolator maintains data integrity when fast-switching IGBT or SiC edges slam the ground reference. In a motor-drive or solar-inverter environment, a part with lower CMTI would glitch or latch, causing spurious faults on the controller side. This rating puts the ADUM2200BRWZ-RL in the tier suited for industrial power stages, not just benign control-room isolation.
2/0 channel direction — one-way barrier, no return path
Both channels are unidirectional from Side 1 to Side 2 (2 inputs on Side 1, 0 on Side 2). That means this part handles two downstream signals — for example, a PWM pair or two SPI data lines — but cannot carry a return signal. If your application needs bidirectional communication (e.g., a half-duplex RS-485 interface), you would need two of these or a part with a reverse channel.
The part is ROHS3 compliant.
16-SOIC wide-body — creepage and footprint
The package is a 16-pin SOIC with a 7.50 mm body width (0.295"), the wide-body variant. The wider body provides the physical creepage distance needed to sustain the 5000 Vrms isolation rating across the barrier. Surface-mount assembly is standard; no special reflow profile beyond the usual for SOIC-16.
