I am beginner in driver circuitry. I am trying to do a MOSFET driver that can work at over 300kHz with a current sink capability of 10A.

I also want it to give a bipolar output like -10/30V.

I found this totem pole circuit with the BC545C PNP and BC557C NPN BJTs (100mA,45V.) In simulation, it it gives me the waveform of -10/30V. I looked at the datasheet of the component and saw that their current sourcing capability is very low.

enter image description here

I tried to use the TIP35C (NPN even with LTspice 2SCR582D3) and TIP36C (PNP same for this model 2SAR582D3) high current sourcing (25A-60V) but I can't get the waveform correct.

What should I add or correct in my circuit?

    \$\begingroup\$ How is the MOSFET hooked up? Also, what MOSFET are you trying to drive? 30Vgs is high. \$\endgroup\$

  • \$\begingroup\$ That's quite extreme. No MOSFETs I'm aware of require +30V, and fewer and fewer require such currents these days -- certainly not at such frequencies. What is your application? Do you know you actually need that much drive power? \$\endgroup\$ Feb 6 at 18:32
  • \$\begingroup\$ You are not using MOSFET's. You are using bipolar transistors. First of all, use MOSFET's if you want to make a driver for them or modify the title of your question (or explain what you want to do exactly). ;) \$\endgroup\$

  • \$\begingroup\$ 1, The GND is placed incorrectly. 2. MOSFET doesn't need negative voltage, SiC MOSFET maybe. 3, Voltages are way too high. 4. Practical implementation would need isolated +/- PSU in order to keep the drain at GND potential. \$\endgroup\$ Feb 6 at 19:30
  • \$\begingroup\$ @MOSFET Thanks for your answer, It's just one mosfets I want to stress (so stress its gate) not to switch for power. \$\endgroup\$
