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.
Package and rework considerations
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. No hidden thermal pad to worry about; all dissipation is through the leads and the board copper.
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.
