If you open your own link, you'll see the "currently unavailable" description. Even if I manage to buy 1 for the testing phase, I highly doubt I'll be able to buy it again in the future (we need 4, one motor per wheel). Time is essentially free as we're students so I don't mind making my own.
My incantation of Amazon shows 3 in stock and delivery sucks (end of May, worst case). There are many others...
The hard bits are guaranteeing sufficient Vgs and Ig to switch quickly. That's the job of the MOSFET gate driver but you need to provide sufficient voltage for the gate driver. If the datasheet shows 10V Vgs then somehow you need to have that much voltage available and with sufficient current capability.
Don't even try to use an N-channel device in the upper position. You need a gate voltage higher than the upper rail to switch the device.
Maybe there is something in here worth knowing:
https://www.ti.com/lit/ml/slua618a/slua618a.pdfMouser has thousands of these n-channel devices in stock
https://www.mouser.com/datasheet/2/196/Infineon-IPD200N15N3%20G-DS-v02_07-EN-1226206.pdfThere are many other selection parameters including p-channel. I didn't check for stock on p-channel and I just went for the TO-220 package figuring the heat sinking would be easy.
Even though the threshold voltage for the device above is as little as 3V (typical), you will notice that most of the specs call for a Vgs of 10-20V.
This may give you a step up on figuring gate current:
https://www.microsemi.com/document-portal/doc_view/14697-making-use-of-gate-charge-information-in-mosfet-and-igbt-data-sheetsYou are right, there are more bogus designs on the Internet than designs that might actually work.
Don't let the rise and fall time become a significant proportion of the minimum ON time. Again, this has the device in the linear region for a more significant percentage of the time. That's one of the reasons that many H-bridges are limited in PWM frequency. They switch too slow and would spend a significant percentage of the period in the switching region at higher frequencies.
What you want is switching in zero time. This takes infinite energy but that's still the goal. Absolute minimum switching time.
