Hello ,
I have a voltage profile as attached here , created by a voltage source connected to a 10A load.
I want to develop a circuit that be interfaced b/w the above voltage source and a micro controller.
The circuit must create an interrupt to the controller whenever the voltage goes from 0 to ~12v or 12 to 0v.
This ckt must avoid intermediate transitions (example ~12v to 4v in 5 ms ramp downing or ramping up ) for interrupt generation.
Please give me ideas.
regards,
jsp
