I would like to know about H-Bridge driver circuit with using ADuM7223.
I understood VDDA and VDDB should be separate supply, but I cannot find any reference circuit.
I also refer to
Is there any information how to VDDA supply when Vbridge voltage max 200V? (This apps note Vbridge is about 16V.)
Actually, one customer had designed with following above pdf Fig.1 with using ADuM7223 instead of ADuM7234 and Vbridge is 200V.
But High-side voltage output is only about 5V instead of 200V.
Thank you for your help in advance.
