The ADUM3223BRZ is a 2-channel isolated gate driver from Analog Devices' iCoupler series. It uses magnetic coupling to provide 3000Vrms isolation between the input logic and the output gate drive, with a peak output current of 4A. This part is designed to drive power MOSFETs and IGBTs in applications where galvanic isolation is required — think motor drives, switch-mode power supplies, solar inverters, and industrial power stages. The 50kV/µs common-mode transient immunity (CMTI) means it won't false-trigger when the switching node slews hard, a common failure point in half-bridge and full-bridge topologies.
The 4A peak output current drives medium-power MOSFETs and IGBTs. The 54ns propagation delay (max) suits synchronous rectification and high-frequency LLC converters.
The ADUM3223BRZ comes in a 16-SOIC (0.154" body width, 3.90mm) package, surface-mount only. That's a standard SOIC-16 footprint — easy to hand-solder or rework with hot air. The body width is narrow enough that it won't shadow adjacent passives under reflow.
Supply voltage and logic interface
The output supply range is 7.5V to 18V, which covers standard gate-drive rails for IGBTs (typically 15V) and MOSFETs (10V to 12V). The input side is powered from the same or a separate supply; the part works with 5V logic directly, and 3.3V logic is also compatible as long as the input thresholds are met — the datasheet should be checked for the exact VIH/VIL levels at your supply voltage.
