1. Electrical circuit comprising a MOSFET and an electronic driver circuit for driving said MOSFET, having four pins including a drain, a gate, a first source and a second source, said MOSFET having an ON state and an OFF state, said electrical circuit comprising at least one electrical track and said MOSFET being connected to said at least one electrical track by way of at least one bond wire, said at least one bond wire having an intrinsic inductance, said electronic driver circuit being connected to the MOSFET by a first terminal linked to the first source and, in parallel, by a second terminal linked to the second source, said at least one bond wire having the intrinsic inductance being arranged between the first terminal and the first source, and
the electronic driver circuit being configured so as to apply an electrical driver signal between the gate and the first source or between the gate and the second source of the MOSFET, in order to trigger a change of state of said MOSFET, and such that:
when the electrical driver signal is intended to transition the MOSFET to the OFF state, the electronic driver circuit applies the electrical driver signal between the gate and the first source, and
when the electrical driver signal is intended to transition the MOSFET to the ON state, the electronic driver circuit applies the electrical driver signal between the gate and the second source.
