I have the following driver circuit used for switching very high current n-channel mosfets
Here's their datasheet https://www.littelfuse.com/~/media/electronics/datasheets/discrete_mosfets/littelfuse_discrete_mosfets_n-channel_trench_gate_ixfn420n10t_datasheet.pdf.pdf )
Here's the circuit that I am trying to build
After trying to build a prototype on a breadboard, I've found that there is no voltage drop across the 1k resistor that is connected to the 2n7000 transistor. As a result, Vgs=0 no matter what the output of the inverter is (High=5 V, Low= 0V). Here's the datasheet of the 2n7000: https://www.onsemi.com/pub/Collateral/NDS7002A-D.PDF
Can anyone tell me what I'm doing wrong with this circuit? I don't think I can ground the source of the 2n70000 because then the driver will share a common ground with the very high current power supply.
