I saw couple of h-bridge circuits based on IR2184 driver that have following circuitry connecting driver and transistor:
My circuit will be full h-bridge driver with load 20A 24V DC motor. I have following questions:
What does this gate circuitry do, does it decreases switching time? Do i need this transil, or zener diode connected to mosfets gate, why is it possible for higher voltage to appear at the gate, is it because of the load? Do i need external reverse diode connected to mosfet when internal diode is sufficient as i think(IRFB4310PbF).
