im operating a 28V contactor using a GPIO from my MCU, i have a 28V supply readily available.
im looking to surpass the gate threshold of the MOSFET by introducing a NPN BJT with a 10V supply, with the base connected to the GPIO,
The MOSFET turns on, however, VGS = V_GPIO - V_BE
and not VGS = 10v - ICRC - V_BE
There is something clear and obvious that im missing?
when the BJT is switched on the voltage should be seen at the gate of the MOSFET??
How can i increase the MOSFET gate voltage without inverting the input?
Thanks in advance.
