Hi ali.kaan, 
 Thank you for using the ADuM4135 in your application. 
 Looks good to me aside from the local decoupling capacitor that will be put close to the ADuM4135 supply pins. 
 I suggest you add 0.1uF close to the VDD2/VSS2 to GND2. Also, D14 should be a fast recovery diode. 
 regarding the DESAT circuit, I believe you will be doing some minor adjustments here to get the right desat response but the configuration looks good. 
 May I know what is your application? 
 Thanks and regards, 
 Jefferson
