Hey everyone,
I wonder if it is possible to drive a logic level mosfet directly from a micro controller.
The IRLZ44N has a Vgs(TH) of 2v, while the µC supplies almost 5v at 25mA or so.
Will that be enough to drive the mosfet into saturation fast enough for a 20KHz+ pwm ?
What gate charge do I need to calculate the current needed to drive the gate ?
Thanks in advance.
