Hey guys.
I'm designing a series pass voltage regulator with feedback. I'm trying to disconnect the load when the load current or control element temperature exceeds a value. The attached photos show my circuit design.
The temperature cutoff circuit works as is, but the current cutoff does not. Instead of a single click, the relay chatters continuously. Can anyone help me fix this?
