Part Number: DRV8305
Hi,
I was wondering what limits the RMS Drive current of the gate driver to 30mA? The datasheet mentions that the charge pump limits this, but is it a thermal issue on the charge pump or possibly a time constant related issue? Is there any way that I could increase this value with better cooling or drive the device at a higher voltage? The switches I'm using need ~80 nC and I'd like to switch at 128kHz which puts me at 60mA RMS using the formula on page 46 of the datasheet. Any help would be much appreciated.
Thanks,
Chris
