Isolated gate driver for power-stage designs
The Analog Devices ADUM3223ARZ-RL7 is a 2-channel isolated gate driver from the iCoupler® family, built around magnetic coupling technology.
Switching performance and timing margin
The 50kV/µs minimum common-mode transient immunity keeps the output state stable during fast dv/dt events on the isolated side — a critical parameter for half-bridge and full-bridge topologies where the high-side switch reference swings rapidly.
The output-side supply range of 4.5V to 18V covers standard gate-drive voltages for both logic-level and standard MOSFETs as well as IGBTs.
Package and approvals
It carries CSA, UR, and VDE safety approvals, simplifying regulatory acceptance for end equipment.
For dual-sourcing or alternative package options, the same die is available in tube (ADUM3223ARZ) or other reel quantities.
