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.

Abstract: A method for detecting a transmission backlash in a hand-held power tool, the hand-held power tool comprising a drive motor that has a drive shaft, a tool spindle, and a transmission that, in respect of drive, connects the drive shaft to the tool spindle, includes actuating, in a first actuation, the drive motor at least until the value of a first variable, representing a drag torque, is at least approximately constant. The method includes, during the first actuation, determining a value of a second variable which is associated with the rotation of the drive shaft of the drive motor during the first actuation, and determining a value of a third variable, representing a transmission backlash, based upon a change in the second variable during the first actuation.

Abstract: A method for determining a remaining service life of a hand-held power tool includes, in an operating mode detection step, detecting an operating mode of the hand-held power tool by an alignment of operating data of the hand-held power tool with a comparative value table stored on the hand-held power tool and/or by a switch position detection function of an operating mode selection switch. In a computing step, the remaining service life of the hand-held power tool is calculated via at least the operating mode and its operating time and output to a user of the hand-held power tool in an outputting step.
