Abstract: A thermal control circuit for an integrated power transistor includes a current generator controlled by a turn on signal, a sensing resistance in series with the power transistor, and a current limiter acting when the voltage drop on the sensing resistance overcomes a certain value. The circuit also includes a current amplifier coupled to the output node of the controlled current generator for outputting a drive current that is injected onto a control node of the power transistor. A soft thermal shut down circuit is provided having a conduction state which is enhanced as the temperature increases for reducing the drive current. The circuit controls the voltage on the power transistor in a more effective manner because the current amplifier has a variable gain controlled by the state of conduction of the soft thermal shut down circuit.

Abstract: An electronic component, such as an IGBT, that presents a control terminal for receiving a stepwise control signal and at least one other terminal adapted for reaching a given voltage level by effect of the application of the step signal, with the possibility of overshoot occurring; and a damping resistive element interposed between the control terminal and the at least one other terminal. The damping resistive element shows a current saturated behavior correlated to voltage increase applied at the terminals towards the given voltage level, thus eliminating the risk of occurrence of overshoot in the voltage of the IGBT collector, and preventing the undesired re-ignition of the IGBT when it is in a cut-off condition, by inducing an overvoltage on the collector terminal. FIG. 5 is the one selected.
