Classification: CPC H  Y | IPC H

Claim 0:
1. A driver circuit for a low-inductance power module, comprising:
a connection; and
an output;
wherein the connection is connectable to a source contact of a power transistor and the output is connectable to a gate contact of the power transistor, and 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; and
wherein the driver circuit is further 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,
wherein the preset minimum time span corresponds to a time span that is required by a short circuit recognition circuit connected to the power transistor to recognize a short circuit when the power transistor is switched on and to initiate and/or carry out a switching off of the power transistor.
