Abstract:
A driver circuit for a low-inductance power module that has a connection and an output. The connection is connectable to the source contact of a power transistor and the output is connectable to the gate contact of the power transistor. The driver circuit is configured to produce, in a first operating mode, a first gate-source voltage for the gate contact of the power transistor and to provide the first gate-source voltage at the output of the driver circuit. The driver circuit is also configured to produce, in a second operating mode, during at least one preset minimum time span, a lower second gate-source voltage for the gate contact of the power transistor and to provide the second gate-source voltage at the output of the driver circuit.
