Hi,
I'm making project where I want to control flash duration with help of MOSFET or IGBT (I will be switching xenon flash bulb in and out of the circuit). I have never used MOSFET or IGBT and I do not know how to drive them. I wan't to drive them with microcontroller (avr) and driver ICL7667. Must I drive MOSFET with some frequency or can I drive them as normal transistors? I read that I must apply around 12V to the gate of MOSFET/IGBT if I wan't MOSFET/IGBT to be fully on?
Is it enough to connect output pin of avr to pin 2 of driver, pin 7 of driver to gate of MOSFET, pin 3 of driver to GND, pin 7 of driver to VCC?
