Other Parts Discussed in Thread: LM5118, , TLV1702, LM2903B,
I have an application where I'm using the LM393 to compare a constant 12V source and a fluctuating 12V battery. I'm using an LM5118 board as a 12V source(powerboard+), and have also used my bench variable power supply in its place just to rule out any interference.
Battery voltage is fed into the positive pin of (one of) the comparators. The constant 12V source is fed into the negative serving as it's reference.
At the moment, the comparator seems to constantly be sinking no matter how the change in the Battery voltage.. All grounds between the 12V supply and battery are shared. I haven't found a short to ground.
This circuit is working in simulation and in my breadboard, I'm at a loss as to why it's not working here.
