Hi,

I have a TC4428 driving a IXFH12N50F MOSFET. Supply is 12V DC.

I expected to get a pretty good rise time from this, but it seems to be at almost 300ns.

If I disconnect the driver from the gate and just measure the output of the IC, it still shows around 300ns. Looking at the data sheet, I thought it should be more like 60ns.

Am I misunderstanding the values on the data sheet, or is there some problem with my circuit?
