I have to interface a specific motor, it has a weird driving board, I was in contact with the technical team from the manufacturer, and they told me that I have to send a -24V on a pin to allow it to turn. I have a +24V power supply, several step down modules, on 5V and 3.3V for my microcontrollers and other things.So here is my question: What is the simple way to produce a -24V voltage source from a 24V or lower one? I have searched a lot, but found nothing... My first idea was an inverting opamp, but if I were able to power it down to -24v then I would'nt need it at all :)
Any Ideas are welcome.
My ideas are now oriented to step down ICs able to output negative voltage from a positive one... I guess something around -18V should be enough to be understood by the driver.
