As reference to CN0196 with an addition ADUM7234 and two n channel mosfets can i drive 3 phase BLDC motor.(When i use 3No.s of ADum7234 and 6 n channel mosfets, can i connect 1st driver to Q1 and Q5, 2nd driver to Q2 and Q6 and 3rd driver to Q3 and Q4)

 

Is R3/R4 resistors so important as i dont find them in some other technical documents.

 

As my requirement is for 230V, 6A switching freq 20KHz. what all considerations should i take, like zener, bootstrap, R3/R4 rating.
