Hello,
I'm trying to drive a MOSFET with a BIPOLAR transistor.
I'm doing simulation but I have an issue
This is my schema :
I drive my BIPOLAR with 0-3v and the MOSFET with a 0-12v (approximatively)
The problem is my BIPOLAR collector resistor is too big, when I turn on the MOSFET there is not enough current going into the gate and it's really slow.
I could take a lower resistor but then my circuit will consume too much current.
So do you know a way to drive my MOSFET quickly ? Can I keep the same circuit or do you know an other one (I heard about totem pole but I'm not sure it's good for my application) ?
Thank you
