Other Parts Discussed in Thread: CSD18533Q5A
I continue to be confused as to how exactly mosfet drivers work and how the datasheet specs them. I'm currently driving TI CSD18533Q5A mosfets through a 10 ohm resistor, similar to the boostxl board. I'm using 1.7A strength. In the below picture blue is voltage measured at GH_C and yellow is SH_C. I'm aware of the ringing, but even still I'm wondering why the mosfets can't turn on faster. I can see that GH_C only goes as high as 6V initially. Is this expected? How is it possible to get 1.7A out of the driver if I can't even get 1A? Is it just that there is a time constant associated with higher current from the driver? Is there any way I can better get information from the drv8301 datasheet to predict mosfet turn on time?
