  • Patent number: 7119586
    Abstract: A circuit arrangement for control of a regulated path and a semiconductor circuit (1) comprises a control connection, with an input, to which a switching signal (3) for control of the semiconductor circuit (1) is applied, an output, to which the control connector of the semiconductor circuit (1) is coupled, a control circuit (2) arranged between input and output. The switching signal (3) may be retained at the current value by means of a hold signal and an analytical circuit (2), which measures a voltage corresponding to the voltage across the controlled path and generates the holding signal for the control circuit (2) for a given duration when the voltage across the controlled path of the semiconductor circuit (1) has a rise which indicates a switching off of the semiconductor circuit (1).
