Yes, i understand this point.. i don't know how you manage to detect errors that fast in a circuit.. i guess its a matter of experience.. anyway,
now here is the only solution i see to that specific problem, but sadly this would mean to lose the Active-turn off capability..
For the deat time, its noted. but when you say dead time, you mean a time where all transistors are OFF before running the bridge in the oposit current direction? to make sure no short circuit happens right?
