Product details

Gate-driver isolation for automotive and industrial power stages

The ADUM3224WCRZ from Analog Devices is a 2-channel isolated gate driver using iCoupler magnetic coupling technology. It delivers 4A peak output current across a 3000Vrms isolation barrier, with a common-mode transient immunity of 50kV/µs minimum. The automotive-grade temperature range (-40°C to 125°C) and CSA/UR approvals make it suited for under-hood traction inverters, DC-DC converters, and on-board charger power stages where galvanic isolation and noise immunity are non-negotiable.

Frequently asked questions

What is the difference between ADUM3224WCRZ and ADUM3223WCRZ?

Both are automotive-grade 2-channel isolated gate drivers with identical 4A peak output, 3000Vrms isolation, 54ns propagation delay, and 12ns rise/fall times. The ADUM3224WCRZ carries CSA and UR approvals; the ADUM3223WCRZ adds VDE certification. The pinout and footprint are the same — the choice hinges on whether your system requires VDE recognition.

Can ADUM3224WCRZ drive MOSFETs and IGBTs?

Yes. The 4A peak output and 11.5V to 18V output supply range are well suited for driving the gate capacitance of power MOSFETs and IGBT modules in half-bridge and full-bridge topologies.

Is ADUM3224WCRZ suitable for automotive applications?

Yes. It is rated Automotive grade with an operating temperature range of -40°C to 125°C, making it suitable for under-hood and chassis-domain applications such as traction inverters and on-board chargers.

Can ADUM3224WCRZ be used as a replacement for ADUM3223?

The ADUM3224WCRZ and ADUM3223WCRZ share the same pinout, package, and key ratings (4A peak, 3000Vrms, 54ns delay). The ADUM3223WCRZ adds VDE approval; otherwise they are functionally interchangeable. Confirm the approval requirement for your target market before substituting.
