Abstract
A temperature sensor circuit for sensing the temperature of an electronic component is disclosed. The temperature sensor circuit comprises a first transistor configured to be thermally isolated from the electronic component and being configured to sense an ambient temperature and a second transistor configured to be thermally linked to the electronic component and being configured to sense a temperature at the electronic component. The temperature sensor circuit is a differential circuit having a first path and a second path with the first and second transistors being arranged on the first and second paths of the differential circuit, respectively, such that the temperature sensor circuit generates an output voltage inversely proportional to a temperature difference between the ambient temperature and the temperature at the electronic component. The temperature sensor circuit also comprises a shut-off switch configured to activate or deactivate the temperature sensor circuit.
