Hi all,
I am making an H bridge for a supply voltage range of 12V to 24V and a max current of 4A. The motor speed will be controlled by a pwm signal (>10kHz) provided by a PIC microcontroller.
I noticed that for driving the gate people use gate drivers (because the gate has some capacitance and it needing more than 5V to fully switch on).
I searched on the internet and came across “boot strap” circuits and so on but did not understand how they operated. Can I use something like a comparator to do this or can someone please provide me with a suitable gate driving circuit.
Regards
