ABSTRACT:
The invention relates to a control circuit and a corresponding method for controlling MOSFETs coupled to the control circuit. The MOSFETs are coupled to a load to couple the load to a power supply, or the MOSFETs are coupled to a generator. In case of inverted polarity, the control circuit switches the MOSFETs to their conducting state to prevent damaging the MOSFETs.
