6.1 Junction Temperature Equation

The following equation is used with the above-mentioned calibration data to improve the temperature sensor reading.

$T_J=\frac{{\mathrm{TSCAL}}_{P1}}{1\mathrm{e}6}+1000\times \frac{\left(\frac{{\mathrm{ADC}}_{\mathrm{VTEMP}}}{{\mathrm{ADC}}_{\mathrm{VBG}}}\times {\mathrm{TSCAL}}_{P6}-{\mathrm{TSCAL}}_{P4}\right)}{{\mathrm{TSCAL}}_{P2}}\mathrm{}$

Where :

• ADC_VTEMP is the averaged ADC measurement of the V_TEMP voltage performed at temperature T_J.
• ADC_VBG is the averaged ADC measurement of the V_BG voltage performed at temperature T_J.
