I have a couple of questions. If using the IRF740 (https://www.kynix.com/components/IRF740-MOSFET-Datasheet-Equivalents-Pinout.html) MOSFET driver, do I still need that gate pull down resistor, or is that included internally in that driver (I noticed the IN+ pin contains a 200K pull down, but wasn't sure if that translated to the gate pin). Second question is, if I use that setup, with the micro going to the MOSFET driver and then to the MOSFET, can I just hook that MOSFET drain straight to the brushed 10A DC motor's "negative" lead with the 12V going to the brushed 10A DC motor's "positive" lead? Assuming I use a fly back diode, like a MBR40100CT?
