I would like to ask for best solution for my issue.
I need high side switch for 24VDC 6mA (it is enable signal for a device).
This device I want to control by Arduino (input 5 V 20mA).
What is the best solutions for this low current?
I tried to use Sziklai pair, but PNP transistor is still open. I don't know how to calculate resistors between NPN and PNP :-(. Do I have to use a sziklai pair or is there something else?
Thank you so much
