Thermal Characteristics
The average chip-junction temperature (TJ) in °C can be obtained from:
Eqn. 1
Where:
TA
= Ambient Temperature,
°C
QJMA
= Package Thermal Resistance, Junction-to-Ambient,
°C/W
PD
=PINT + PI/O
PINT
=IDD × IVDD, Watts - Chip Internal Power
PI/O
= Power Dissipation on Input and Output Pins — User Determined
For most applications PI/O < PINT and can be ignored. An approximate relationship between PD and TJ (if PI/O is neglected) is:
Eqn. 2
Solving equations 1 and 2 for K gives:
Eqn. 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 Equation 1 and Equation 2 iteratively
for any value of TA.

JA, θJMA and Ψjt parameters are simulated in conformance with EIA/JESD Standard 51-2 for natural convection.
Freescale recommends the use of
θ
JmA and power dissipation specifications in the system design to prevent device
junction temperatures from exceeding the rated specification. System designers should be aware that device
junction temperatures can be significantly influenced by board layout and surrounding devices. Conformance to the
device junction temperature specification can be verified by physical measurement in the customer’s system using
the
Ψ
jt parameter, the device power dissipation, and the method described in EIA/JESD Standard 51-2.
