Abstract
An electric circuit configuration for shaping the slew rate of a pulsed output voltage occurring at an output terminal and for detecting a short circuit at the output terminal, having: a switchover control circuit for controlling the slew rate of the output voltage as a function of a voltage curve occurring across an internal resistor in a first switching state, and for feedback-controlling the slew rate as a function of the output voltage curve in a second switching state, and which is in a substantially dead state in a third switching state; a detector circuit which provides a detection signal when the output voltage differs by at least a predetermined value from the output voltage level occurring before edge onset; and a timer circuit for switching the control circuit from the first to the second switching state a predetermined length of time after edge onset if the detection signal is present at this time, and from the first to the third switching state if the detection signal is not present at this time.
