The average chip-junction temperature (TJ) in C can be obtained from:
TJ = TA + (PD JA)
Eqn. 1
where:
TA = Ambient temperature, C
JA = 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 + 273C)
Eqn. 2
Solving Equation 1 and Equation 2 for K gives:
K = PD (TA + 273C) + JA (PD)

Junction temperature is a function of die size, on-chip power dissipation, package thermal resistance, mounting site
(board) temperature, ambient temperature, air flow, power dissipation of other components on the board, and board
thermal resistance.
