Abstract
A heating device is provided. A temperature sensing unit is configured to sense an ambient temperature and accordingly output a temperature sensing voltage. A driving unit is coupled to a heating transistor unit and the temperature sensing unit, and configured to drive the heating transistor unit for performing heating based on the temperature sensing voltage. An activating unit is coupled to the temperature sensing unit, configured to output an activating signal based on the temperature sensing voltage when a temperature of the printed circuit board has risen up to a preset temperature. The heating device as provided can assure that the activating signal can be normally outputted by the heating device under an ambient at an extremely low temperature.
