7.3.6.1 Temperature Sense Diode Theory

A temperature sensing diode is based on the fundamental current and temperature characteristics of a transistor. The diode is formed by connecting the transistor base to the collector. Two different known currents flow through the diode and the resulting diode voltage is measured in each case. The difference in the base-emitter voltages is proportional to the absolute temperature of the transistor.

Refer to the TMP411-Q1 Data Sheet for detailed information about temperature diode theory and measurement. Figure 7-2 and Figure 7-3 illustrate the relationship between the current and voltage through the diode.
