Abstract
A safe operating area circuit in combination with a current sensing circuit is coupled to an input voltage line and has a control line input in which the combination provides a current limited output on an output voltage line in response thereto. Break-points may be selectably established in the current limit curve for the output switching device by means coupling the input and output voltage lines.
