I have been using a circuit like the attached pic for low powered h-bridges.
My problem is speeding up the switching times for large gate charges or multiple mosfets.
If i use too many Mosfets in Parallel the circuit starts behaving like an on/off switch unless i lower the PWM frequency, which, to me means the switch is turning on but not discharging before the next pulse so it acts like its always on, nothing gets hot.
I know i can use gate drivers for this but i have lots of discrete components.
So my questions are:
When the gate is switched off is the gate charge all discharged through the 10k resistor to ground?
Can i reduce the gate pulldown resistance to speed this up?
