What the ADUM5202ARWZ-RL brings to a BOM
The ADUM5202ARWZ-RL is a two-channel digital isolator from the iCoupler and IsoPower families, combining signal isolation with an integrated isolated DC-DC converter in a single 16-SOIC package. It uses magnetic coupling to achieve 2500Vrms isolation between the input and output sides, with a data rate of 1Mbps and propagation delays of 100ns max. The built-in IsoPower regulator means you don't need a separate isolated supply transformer or a third-party DC-DC module for the isolated side — a real BOM simplification for designs that need a clean, isolated power rail for sensors, transceivers, or control logic.
The 2500Vrms isolation rating is the basic insulation level for this part. It's sufficient for reinforced insulation in many industrial and medical applications where the working voltage stays under 300Vrms. The common-mode transient immunity of 25kV/µs min means the part won't glitch when fast voltage transients slam across the isolation barrier — important in motor-drive or inverter environments where the ground potential can jump sharply.
Supply rails and channel configuration
The ADUM5202ARWZ-RL has two separate supply domains: the logic side runs from 3V to 5.5V, and the IsoPower side (which generates the isolated output power) needs 4.5V to 5.5V on its input. The two channels are both on Side 2 (the isolated side), so this part is set up to receive signals from the non-isolated side and pass them across the barrier — unidirectional, Side 1 to Side 2. If you need bidirectional or more channels, look at the ADUM5201 (one channel) or ADUM540x family (four channels).
Package, temperature, and storage considerations
Housed in a 16-pin SOIC with 7.50mm body width (the wide-body version), the ADUM5202ARWZ-RL gives you the creepage distance needed for 2500Vrms isolation.
