Hi everybody out there !
I'm having problems with a LM393 (open collector output)used as a
voltage controller to a 12V lead battery: when voltage drops below
minimum voltage a
battery-low signal is issued. Connected to the 10k Ohm pull-up
resistor is a cpu-reset push-button, fed in to a flip-flop. What
happens is that somehow, after
a number of reset-button presses, the LM393 shorts its output to
ground even if according to input signal levels I expect it to go
high. So whats the buzz???
Thanks a Ton
