Drive circuit with adjustable dead time

摘要

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.

1. A drive circuit, comprising:
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; wherein 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 wherein the drive circuit is further configured to evaluate at least one electrical parameter of the mode selection element and is configured to adjust a maximum signal level of the first drive signal and a maximum signal level of the second drive signal dependent on the evaluated parameter and to adjust the dead time dependent on the evaluated parameter.
