Re: Level shifter issues

If the mosfet driver has a rating of maximum 1.5A *peak* current and tries to charge a parasitic capacitance that tries to draw 10A peak current, that cant be good. It may work, but its not inside datasheet parameters, or it may burn or else. I think its like when the mosfet driver upper mosfet starts conducting, it starts conducting a peak of 10A when its only rated for a peak of 1.5A, that means its probably going to fry or enter protective mode if it has one. Perhaps some smarter drivers can detect and limit the current automatically if have this as a function. Else, if we put a resistor in line with the current path this way it can limit the current peak to keep the driver in safe operating area. But rising edge will change and charging will be slower (plus the rc filter effect if we think of pid pwm) - and that would make on-off times in datasheet sort of irrelevant. Alternatively we can go with another mosfet driver that has 10A peak rating, and advantage is that we take resistor away, plus it will also charge in fastest time possible - up to the mosfet driver's on and off times. Why wouldnt be like that, what do you see or think differently?
