It provides 2500Vrms galvanic isolation between the input logic side and the output power stage, with each of its two channels capable of delivering 4A peak drive current to the gate of a power switch. This part is built around magnetic coupling technology, which gives it a common-mode transient immunity of 25kV/µs minimum — a spec that matters directly in motor drives, inverters, and switched-mode power supplies where fast voltage slewing across the isolation barrier can corrupt data or latch up a weaker isolator. The output supply range spans 4.5V to 18V, so it can drive standard MOSFETs at 10V or 12V gate drive, or IGBTs at 15V, without needing an external level shifter. Propagation delay is 60ns max in both directions, which keeps dead-time budgets tight in half-bridge and full-bridge topologies. ## 4A peak drive — what it can and can't switch The 4A peak output current rating means this driver can charge and discharge the gate capacitance of medium-power MOSFETs and IGBTs quickly enough for switching frequencies up to several hundred kilohertz. For a typical 10nC total gate charge device, the 20ns rise and fall times translate to a gate-drive slew rate that keeps switching losses manageable. That said, 4A peak is not in the league of the 9A or 10A isolated drivers used for large IGBT modules in traction drives or high-power inverters. If you are driving paralleled SiC MOSFETs with high gate capacitance, the 4A peak may be marginal — you would want to check the total gate charge against the driver's source/sink capability at your switching frequency. ## Package and temperature — board-fit realities The ADUM3220ARZ comes in an 8-SOIC package with a 3.90mm body width, surface-mount only. The 8-SOIC footprint is standard, but note there is no exposed thermal pad — all dissipation goes through the plastic body and the leads. The approvals from CSA, UR, and VDE mean the 2500Vrms isolation rating is certified to international safety standards, which simplifies the safety compliance submission for end equipment sold into North American and European markets.","metaTitle":"ADUM3220ARZ iCoupler Digital Isolator, 2500Vrms","metaDescription":"ADUM3220ARZ ADI iCoupler dual-channel gate driver with 2500Vrms isolation, 4A peak output, 25kV/µs CMTI.
