Abstract: A level converter is disclosed. In one embodiment, the level converter includes a first and second input for applying a first voltage and first and second output terminals for providing a second voltage, a first RC element, and a second RC element, and a first controlled current source arrangement and a second controlled current source arrangement. A control signal generating circuit is provided that generates a control signal for the first and second current source arrangements and has at least one differential amplifier arrangement which is designed to compare a potential at at least one of the outputs with a reference potential and to generate a differential signal on which the control signal is dependent.

Abstract: A circuit arrangement comprises a level shifter which is supplied with a first signal and which provides a level-shifted second signal, at least one load which is supplied with the second signal as an actuating signal, at least one voltage regulator, for providing a supply voltage for the at least one load, which has a connection for supplying a signal that sets the current yield of the voltage regulator arrangement and which is supplied with a signal, as a setting signal, that is dependent on the at least one first signal.

Abstract: A method and device for detecting the motor position of a DC motor includes evaluating the back-induced voltage of non-energized motor windings of the motor only during predetermined time durations whose temporal position and duration are derived from drive signals for half-bridge circuits that are connected to the motor windings.
