Temperature detection cell, and method to determine the detection threshold of such a cell |
摘要 |
A temperature detection cell includes a circuit for producing a voltage that increases with temperature, a circuit producing a voltage that decreases with temperature, and a comparison circuit to compare the increasing voltage with the decreasing voltage. The comparison circuit produces a warning signal when the temperature reaches a detection threshold such that the decreasing voltage becomes lower than the increasing voltage. The cell also has a test circuit to determine the detection threshold of the cell. Also disclosed is a method for testing a temperature detection cell, during which the detection threshold of a cell is determined from measurements of the increasing voltage and the decreasing voltage at a reference temperature.
