1. An electrosurgical generator for supplying electrosurgical energy to tissue, the electrosurgical generator comprising:

  • sensor circuitry coupled to at least one return electrode pad and configured to determine tissue temperature at a return electrode pad site;

    a processing device configured to determine a maximum temperature of tissue at the return electrode pad site based on at least one characteristic of a patient; and

    a controller configured to regulate output of the electrosurgical generator based on the tissue temperature and the determined maximum temperature.
