The 2500Vrms isolation rating provides the galvanic barrier needed between the low-voltage PWM controller and the high-side switch in motor drives, PFC stages, and isolated DC-DC converters. With a 25kV/µs common-mode transient immunity it handles the fast dV/dt edges from SiC or GaN devices without corrupting the gate signal. ## Supply range and timing — fitting into the power-stage design The output supply range of 4.5V to 18V covers common gate-drive rails for both logic-level MOSFETs (10V) and standard IGBTs (15V). Propagation delay is 60ns max with 20ns rise/fall times, which keeps switching losses in check for PWM frequencies up to several hundred kilohertz. The two channels are independent, so you can drive a high-side and low-side switch from one package, or parallel them for higher peak current into a single gate. For procurement, this means no last-time-buy scramble and no forced redesign for the foreseeable future.","metaTitle":"ADUM3221ARZ-RL7 iCoupler Gate Driver, 4A Peak, 2500Vrms","metaDescription":"ADUM3221ARZ-RL7 isolated gate driver with 4A peak output, 2500Vrms isolation, 25kV/µs CMTI.
