    Hello Aki,

    Thank you for the schematic. The schematic looks good, and I do not expect any issues. Please make sure that the decoupling capacitors are placed as close as possible to the supply pins. 

    I noticed the schematic uses an optocoupler, would it be possible to use ISOM8110 in this spot? It looks to be a good match, however the CTR may be different. 

    Best,
    Andrew
