Thermal characteristics
The average chip-junction temperature, T
following equation:
Where:
P
Most of the time for the application P
may be significant if the device is configured to drive continuously external modules and/or
memories.
An approximate relationship between P
Therefore (solving equations 1 and 2):
where:
K is a constant for the particular part, which may be determined from equation (3) by
measuring P
may be obtained by solving equations (1) and (2) iteratively for any value of T
