It delivers 4 A peak output current across a 2500 Vrms isolation barrier, with a common-mode transient immunity of 25 kV/µs minimum and matched 60 ns propagation delays on both edges. The part is rated for the full -40 °C to 125 °C industrial temperature range and comes in an 8-SOIC package. Typical applications include IGBT and MOSFET gate drive in motor drives, industrial power supplies, solar inverters, and isolated DC-DC converters where reinforced isolation and fast, clean switching are required. ## 4 A peak drive — what it means for the gate loop The 4 A peak output current charges gate capacitance within the required switching window. With 20 ns typical rise and fall times, the driver handles gates in the tens of nC range. ## Isolation and transient immunity for inverter environments With 2500 Vrms reinforced isolation and a minimum common-mode transient immunity of 25 kV/µs, this driver is built for the noisy, high-dV/dt environment of a motor-drive inverter or a power-factor-correction stage. The 60 ns maximum propagation delay on both edges is matched, which simplifies dead-time calculation in half-bridge and full-bridge topologies — the designer can budget the same delay for turn-on and turn-off without adding margin for mismatch.","metaTitle":"ADUM3221BRZ iCoupler Isolated Gate Driver, 4 A, 2500 Vrms","metaDescription":"ADI ADUM3221BRZ isolated gate driver: 4 A peak, 2500 Vrms, 25 kV/µs CMTI, 60 ns prop delay.
