Hi,
I have a MCU with +3.3V output pins, I will need to power down a device which expects -3.3V signal (it takes no more than 0.5mA current from this signal, it only expectes the negative voltage level).
How could I accomplish this? should I use a P-channel MOSFET, N-Channel? JFET? do you have a recommendation for a +3.3V logic level transistor?
Thank you very much in advance!
