H-bridge 2 motors 12V


I have a little, silly question and I'm asking it just to be sure. I have a H-bridge (L293D) for driving 2 motors (of each 12V). For the motor current pin on the H-bridge, should I provide 12V or should it be 24V?
I think it should be 24V, but I'm not sure.


No, 12V.

Except that there will be a drop of about 2V through the chip, I can't recall exact value, so you need to supply enough to cover that.

And remember that the 293D provides only 600mA current per motor, so you need to be satisfied that's enough.
