lemming:
Most circuits for driving a fet show the inverting setup as show below.
I would like to keep the logic intuitive by having the fet output go high when the micros pin goes high.
That circuit works as follows.
Arduino OUT = LOW, Q2 OFF, Gate of T1 pulled HIGH to 12V wrt Source, Drain of T1 = LOW (0V)
Arduino OUT = HIGH, Q2 ON, Gate of T1 pulled LOW to 0V wrt Source, Drain of T1 = HIGH (12V).
Where is the inversion?
Unless you talk about LOAD current with Low Side Switching
Arduino OUT = LOW, Q2 OFF, Gate of T1 pulled HIGH to 12V wrt Source, Drain of T1 = LOW (0V), LOAD Current flows.
Arduino OUT = HIGH, Q2 ON, Gate of T1 pulled LOW to 0V wrt Source, Drain of T1 = HIGH (12V). No LOAD Current flows.
Which is the OP talking about.
