Abstract
A drive circuit includes a first input terminal configured to receive a first input signal, a first output terminal configured to provide a first drive signal, a second output terminal configured to provide a second drive signal, and a mode selection terminal configured to have a mode selection element connected thereto. The drive circuit is configured to generate the first and second drive signals dependent on the first input signal such that there is a dead time between a time when one of the first and second drive signals assumes an off-level and a time when the other one of the first and second drive signals assumes an on-level, and evaluate at least one electrical parameter of the mode selection element and is configured to adjust a first signal range of the first drive signal and a second signal range of the second drive signal dependent on the evaluated parameter and to adjust the dead time dependent on the evaluated parameter.
