Sometimes it is cheaper in small quantities to have someone make your parts vs building your machines to do the job. Plasma cutters do not make clean enough cuts as needed for control panels. Anyway...
no gate driver needed for occasional intermittent switch... the rise and fall times are where there is power dissipated in the mosfet...... do a calculation of the power dissipated in that 30 micro...
.
usually, all the gate drive circuits mostly have to do with the frequency the mosfet is engineered to operate. That is where high frequencies matter and the rise and fall times of the mosfet...

Re: Calculating base resistor on mosfet AO3400A
You can drive the MosFet directly from PIC as your frequency of activations is really slow.
Ioannis - 26th July 2025, 10:57Gate driver is needed if your frequency is high. Also resistors or ferrite beads are also neededin...
