Hey guys,
I am trying to drive a mosfet using pwm from an arduino, however, the low 5 volts is not enough to fully conduct for the mosfet I am using. My other option is to then use a gate driver to drive the mosfet. My question is, why can't I just use a logic level mosfet to control the regular mosfet I am using to turn it on and off? What are the drawbacks of doing so? What are the benefits of using a gate drive? Also, I have never used a gate driver before. Is it correct that to get a driving voltage of say 18 volts, I must also have a 18 volt voltage source? All help is appreciated. Thank you!
