Product details

The ADUM3224WARZ: It delivers 4A peak output current and provides 3000Vrms galvanic isolation between the input logic and the output drive stage.

4A peak drive — sizing the power stage

The 4A peak output current charges gate capacitance. The 12ns rise and fall times (typical) and 54ns maximum propagation delay (both edges) are symmetrical, which simplifies dead-time calculation in half-bridge and full-bridge topologies.

Package and supply rails

The part comes in a 16-SOIC package with a 3.90mm body width — the narrow SOIC-16 footprint common in automotive modules. It is surface-mount only, so no socketed replacement in the field. The output supply range (4.5V to 18V) covers the typical gate-drive voltages for IGBTs (15V) and SiC MOSFETs (18V), as well as logic-level MOSFETs at 5V. The input side is powered from the same 4.5V to 18V rail or a separate isolated supply — the datasheet application circuits show the usual bootstrap or isolated DC-DC arrangement for the high-side channel.

Lifecycle and sourcing

It is ROHS3 compliant and available through independent distribution. There is no LTB risk on this part today.

Frequently asked questions

What is the equivalent or replacement for ADUM3224WARZ?

Within the same ADUM3224 family, the ADUM3224WBRZ and ADUM3224WCRZ are pin-compatible alternatives that offer a higher common-mode transient immunity of 50kV/µs minimum versus the WARZ's 25kV/µs. Both are also automotive-grade and share the same 4A peak output, 3000Vrms isolation, and 16-SOIC package. If your system needs the higher dv/dt immunity, the WBRZ or WCRZ is the direct upgrade path.

Is ADUM3224WARZ automotive qualified?

Yes, the ADUM3224WARZ is an automotive-grade part, as indicated by the 'W' in the order code.
