To effectively drive Power MOSFET’s you need about 12 Volt and enough current to charge the gate fast.
Surprisingly, a NE555 timer makes a good MOSFET driver converting standard logic levels of 1.8 to 5 V to a gate drive signal of 12V at 200mA, which is enough for many applications!
In this video I will explain how the circuit works, then I will build it and test the circuit to its limit to show its advantages and disadvantages.
