ADuM7223 as a replacement for UCC21225

Hello, we are using UCC21225 in our project.

We want to replace this with the ADuM7223 series.

Both drivers are almost pin compatible. Except for pin 4 and pin 6.

From the ADuM7223 data sheet, I realized that the pins are not internally connected.

Can you confirm this?

What aspects need to be considered when replacing.

We use the ADuM7223 as the half-bridge driver. Vdd1 = 3v3, Vdda and Vddb = 15V.

Many thanks
