12.5 Thermal Characteristics
12.6 Power Considerations
The average chip junction temperature, TJ, in °C can be obtained from:
TJ = TA + (PD x θJA)
(1)
Where:
TA = ambient temperature in °C
θ
JA = package thermal resistance, junction to ambient in °C/W
PD = PINT + PI/O
PINT = ICC × VCC = chip internal power dissipation
PI/O = power dissipation on input and output pins (user-determined)
For most applications, PI/O < PINT and can be neglected.
Ignoring PI/O, the relationship between PD and TJ is approximately:
(2)
Solving equations (1) and (2) for K gives:
= PD x (TA + 273°C) + θJA x (PD)
2
(3)
where K is a constant pertaining to the particular part. K can 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 can be obtained
by solving equations (1) and (2) iteratively for any value of TA.
