Thermal characteristics
The average chip-junction temperature, TJ, in degrees Celsius, may be calculated using the
following equation:
TJ = TA + (PD x ΘJA)(1)
Where:
–TA is the ambient temperature in °C,
Θ
JA is the package junction-to-ambient thermal resistance, in °C/W,
–PD is the sum of PINT and PI/O (PD = PINT + PI/O),
–PINT is the product of IDD and VDD, expressed in Watts. This is the chip internal
power,
–PI/O represents the power dissipation on input and output pins; user determined.
Most of the time for the applications PI/O< PINT and may be neglected. On the other hand,
PI/O may be significant if the device is configured to drive continuously external modules
and/or memories.
An approximate relationship between PD and TJ (if PI/O is neglected) is given by:
PD = K / (TJ + 273°C)
(2)
Therefore (solving equations 1 and 2):
K = PD x (TA + 273°C) + ΘJA x PD
2
(3)
Where:
K is a constant for the particular part, which may be determined from equation (3)
by measuring PD (at equilibrium) for a known TA. Using this value of K, the values
of PD and TJ may be obtained by solving equations (1) and (2) iteratively for any
value of TA
