I've been searching high and low for an ultra-low power LVD circuit (Low Voltage Disconnect) for batteries and found the attached diagram on the web.
I think I have a reasonable understanding of the working principle, but there is one particular part that looks strange to me:
Take a look at the connection marked in red. Does it pass through the inverter or does it go directly from switch S1 to ground? The latter seems odd, since this would short-circuit the whole thing once you press switch S1.
I do realise that S1 is only a push-button and not a regular switch, but still......
Being a newbie I would love some help in understanding how this could possibly work in reality.
