This document describes the features and characteristics of the ADuM3220/ADuM3221 dual-channel gate driver, including 4A peak output current, precise timing characteristics, high-temperature operation, input logic range, etc.
The ADuM3220 and ADuM3221 are 4 A isolated, dual‑channel gate drivers that use Analog Devices' Coupler™ technology to deliver high‑speed CMOS performance with galvanic isolation. They are intended for use in isolated synchronous DC‑DC converters and MOSFET/IGBT gate‑driver applications.
The handbook includes detailed electrical characteristics for 5 V and 3.3 V operation, package dimensions, regulatory approvals, pin‑out tables, truth tables, and safety‑related specifications. Key performance figures such as propagation delay, output current, and isolation voltage are listed in the specifications section.
| Peak output current | 4 A |
|---|---|
| Maximum propagation delay | 60 ns |
| Channel‑to‑channel matching | 5 ns |
| Output drive voltage range | 4.5 V to 18 V |
| Isolation voltage rating | 2500 V rms (1 s) |
Each channel can deliver a peak output current of 4 A.
The maximum isolator and driver propagation delay is 60 ns.
They are rated for 2500 V rms isolation per UL 1577 for a 1‑second test.
