I need a dual / quad voltage comparator circuit to control a transistor switch. One comparator used as a thermistor temp control, and the other to monitor low battery voltage. Do I need logic gates as well, or can these two outputs go into a third comparator? There are 4 on the 339 chip.
Here is the logic:
(Temp ABOVE a set value = 1, below = 0 )
Battery BELOW a set voltage = 0, above = 1 )
Final output Temp Battery voltage
1 1 1
0 1 0
0 0 0
0 0 1
Thanks,
Jules
