Abstract
A transistor is driven by a drive circuit that includes a logic unit and drive signal generator. The drive signal generator outputs a temporally variable drive voltage for driving the transistor, based on setpoint state information. A short-circuit information signal contains information about a possible short circuit of a load connected in series with the transistor load path. In response to this signal, the drive signal generator switches on the transistor at a first point in time by setting the transistor drive voltage to a value or a value range above a switch-on threshold value of the transistor, but limits the drive voltage to a maximum first switch-on voltage limit value. The drive signal generator maintains the drive voltage at maximally the first switch-on voltage limit value or sets the drive voltage to a value or a value range greater than or equal to a second switch-on voltage limit value.
