θJA = Package thermal resistance, junction-to-ambient, °C/W
PD = Pint + PI/O
Pint = IDD × VDD, Watts - chip internal power
PI/O = Power dissipation on input and output pins - user determined
For most applications, PI/O << Pint and can be neglected. An approximate relationship
between PD and TJ (if PI/O is neglected) is:
PD = K ÷ (TJ + 273 °C)
Solving the equations above for K gives:
K = PD × (TA + 273 °C) + θJA × (PD)2
where K is a constant pertaining to the particular part. K can be determined by measuring
PD (at equilibrium) for an known TA. Using this value of K, the values of PD and TJ can
be obtained by solving the above equations iteratively for any value of TA.
