Hi all
I've been asked to adapt a small logitech sundsystem to run off an 12v lead acid battery, and for that I want to add a low voltage cutoff circuit to protect against over discharge of the batt.
I've come up with this circuit, and I would like to know if it looks ok?
Also would it better the stability if the LM393 is supplied with a constant 5V from the AN7805, would that even work?!?
Regards.
