Zusammenfassung: | A device for current sensing of a power transistor system having a power transistor, a first series circuit which includes a first transistor and a first resistance, the first resistance disposed in a load circuit of the first transistor, a second series circuit which has a second transistor and a second resistance disposed in a load circuit of the second transistor, the first series circuit, the second series circuit and the power transistor situated in parallel with one another, the first resistance connected to the first transistor in an electrically conductive manner when the first transistor is switched on, and the second resistance connected to the second transistor in an electrically conductive manner when the second transistor is switched on, and a gate terminal of the first transistor is connected in an electrically conductive manner to a gate terminal of the power transistor when the power transistor is switched on. |
