I wondered if anyone had any circuits that I could add on to this circuit for my project!
I've designed a current limiter for my speed control using a LM358. The output stage is shown below, and it works fine and triggers like it should.
The problem however, is that when its triggered, its only triggered momentarily. So the motor turns off when its over current then straight back on, then straight back off etc.
The output is 5V which at the moment is connected to the Shutdown pin of the driver IC.
Can anyone think of any way using discrete components that I could add an adjustable time turn off delay in this? I would like 5-10 seconds if possible?
The circuit is run from 12V, and the output from the circuit is 5v with about 14ma which is enough to trigger the shutdown.
