Integrated isolated power in a 20-SSOP package
The ADUM5211BRSZ-RL7: This means the part provides both signal isolation and a regulated, isolated power output from a single 20-SSOP package, eliminating the need for a separate isolated supply module. It uses magnetic coupling (iCoupler technology) for the data channels and delivers 2500Vrms of galvanic isolation, rated for continuous operation across -40°C to 105°C. The integrated power rail simplifies BOM layout in space-constrained designs like motor-drive interface boards, PLC I/O modules, and medical sensor front-ends where a clean isolated supply is needed for the secondary-side circuitry.
25Mbps data rate — matched to control and sensor buses
With a 25Mbps data rate and 35ns max propagation delay (tpLH/tpHL), this part is sized for SPI, UART, and low-to-mid-speed control signals. The 2.5ns typical rise/fall time keeps edge rates clean for 3.3V and 5V logic families without excessive ringing. Pulse-width distortion is held to 3ns max, which matters for clocked interfaces where duty-cycle symmetry affects timing margin. The 25kV/µs common-mode transient immunity ensures data integrity in noisy inverter or motor-drive environments where fast voltage transients couple into the isolation barrier.
Supply range and power output
The supply range of 2.7V to 5.5V on both sides allows direct connection to 3.3V or 5V logic rails without external level shifters. The integrated IsoPower converter generates an isolated output voltage on the secondary side — the part's description confirms isolated power is present. This output can power small loads like an isolated sensor or a secondary-side transceiver, reducing the need for a separate DC-DC converter.
