3000 Vrms isolation with 4 A peak gate drive
The ADUM3223ARZ is a 2-channel isolated gate driver from Analog Devices' iCoupler series, built around magnetic coupling technology. This combination suits it for driving MOSFETs and IGBTs in motor drives, industrial power supplies, and inverter stages where galvanic isolation is required between the controller and the power stage.
59 ns propagation delay and 50 kV/µs CMTI — timing margin in noisy environments
The 59 ns max propagation delay (both tpLH and tpHL) is symmetric, which simplifies dead-time calculations in half-bridge topologies. The 50 kV/µs minimum common-mode transient immunity means the output state holds clean through fast voltage swings on the high-side rail — a common failure point in motor-drive and UPS designs where the ground reference jumps during switching events. Rise and fall times are 12 ns typical.
For volume or scheduled orders, the part is quoted against an RFQ with confirmed pricing and lead time at the time of request. Approvals from CSA, UR, and VDE reinforce its suitability for safety-certified equipment designs that require recognized isolation components.
