Hi all, I have been trying to get a MCU to send a +5v signal and in turn switch a N channel MOSFET with a VDS of +12v. I used a P channel BJT, tied the gate to +12v through a resistor, the top to +12v straight, and the output to the gate of the MOSFET. Then by grounding the gate, the pchannel sourced the +12v needed and the MOSFET turned on. However this only worked for some of the p channel transistors I had (even if they were both the same), so something must not be right. What is the best way to accomplish this? It has to be a common problem, and I have tried about 5 solutions with varying degrees of success from sparatically to some of the time working, but never consistant.
