Abstract
An electronic circuit includes a node coupled to a load to be driven, and a power device, which can be switched between activation and deactivation and coupled to the node. The circuit further includes a current generator having an output connected to the node and that can be enabled to generate current at least when the power device is deactivated. The circuit also includes a comparator for comparing an electric voltage of the node with a reference voltage and is configured to generate a comparison signal based thereon.
