Hi
I am trying to create a circuit which i can use as a voltage controlled switch.
I have 2 voltage inputs,
** A constant 3V source V1,
** A source which charges up to 3.5V and then slowly discharges V2.
I would like to amalgamate both sources so as when V2 discharges below 3V the V1 will be used allowing V2 to charge back up to 3.5V e.t.c
I have done some research and i believe that an Op Amp voltage comparator can be used for this and believe that i can implement the LM393 but am struggling to design a circuit that can do this operation.
Can any help and explain how this can be achieved.
