Dear Sir / Madam :
I use ACPL-36JT in my Gate drive board design to drive IGBT model; there is DESAT fault problem on switch ringing.
my High voltage is 270V;
when switching, The switcher collector Pin can go to -10V; then ACPL-36 make a fake DESAT fault.
Could you tested ADUM4136 under this ringing condition?
If there is no fake DESAT fault; I'll replace gate drive chip with ADUM4136.
