Hello,
I am looking for a design or a component which will perform the following functions:
The thing about this component is that it must be "powered" by the input itself and must be able to start operating as the input voltage rises. It must use very little power itself since the application is for small scale solar/super capacitor operations with very little power to spare.
Anyone got some good ideas for this type of project?

I am looking for a design or a component which will perform the following functions:
- It will connect a power source like a battery or a super capacitor to a load, acting as a switch in between.
- It will turn off the load when the input voltage drops below X
- It will turn on the load when the input voltage reaches Y - X and Y serve as hysteresis lower and upper bounds
- Very energy efficient, able to run without any external power source
- If the input voltage starts at 0, the load will be off (disconnected).
- When the voltage rises (for example if a solar panel is charging the capacitor or battery), the unit will wait until the voltage reaches Y.
- When the voltage reaches Y, it will enable the load.
- The load will now cause the voltage to drop below Y again - which should be allowed and not cause the load to be disconnected. Only as the load drains the battery or cap below X is the load disconnected.
- Go back to step 2.
