uln2803 hot
I'm making a stepper driver with ULN2803. It's working, but the IC heats up very quickly. I'm not using microstepping. I'm using two outputs paralleld together, totaling one ULN IC per driver (8 outputs / 2 = 4 outputs, as needed for uniploar driving).
Is it safe to operate the ULN in high temps?Or should I get some cooling? Is there cooling for DIP packages?
