Product details

Automotive isolated dual gate driver in 16-SOIC

50kV/µs CMTI — why it matters for motor drive

Minimum common-mode transient immunity is 50kV/µs. Rise and fall times are 12ns typical; propagation delay is 54ns max on both channels.

The output supply range of 7.5V to 18V covers the typical gate drive voltages for silicon IGBTs (15V) and SiC MOSFETs (18V). The 4A peak output current can directly drive a standard IGBT module gate charge of several hundred nC without an external booster stage, though a small gate resistor is still needed to control ringing. The part is approved by CSA and UR, which simplifies system-level safety certification for industrial and automotive power stages.

It remains a current-design-in part for new automotive and industrial power projects.

Frequently asked questions

What is the difference between ADUM4224WBRWZ and ADUM4223WBRWZ?

Both are automotive-grade 2-channel isolated gate drivers with 5000Vrms isolation, 4A peak output, 12ns rise/fall, 54ns propagation delay, and the same 16-SOIC package. The ADUM4224WBRWZ has a minimum CMTI of 50kV/µs, while the ADUM4223WBRWZ also carries 50kV/µs — the key difference is the ADUM4223 variant includes VDE approval in addition to CSA and UR. For most motor-drive applications the two are functionally interchangeable, but check your system's safety certification requirements for the VDE mark.
