Abstract
An electronic circuit includes an electronic switch having a control terminal and a load path. A monitoring circuit includes a switched-capacitor circuit with a capacitive storage element. The switched-capacitor circuit is coupled to the load path of the electronic switch. The monitoring circuit is operable to evaluate a load voltage of the electronic switch and to generate a failure signal dependent on the evaluation. A drive circuit is operable to provide a drive signal at the control terminal of the electronic switch dependent on the failure signal.
