• ISO5452: Is there any concern with 9V DESAT threshold voltage?

  

  Aki Li

  Resolved

  Part Number: ISO5452 Customer was concerned about 9V of the DESAT threshold voltage of ISO5452, since they are afraid the short circuit current might go up a lot until the voltage reaches up to 9V. I believed it should be okay if using a small capacitor…
