Thermal Characteristics
The temperature variable in the Designer software refers to the junction temperature, not the ambient
temperature. This is an important distinction because the heat generated from dynamic power
consumption is usually hotter than the ambient temperature. EQ 1, shown below, can be used to
calculate junction temperature.
EQ 1
Junction Temperature =
T + Ta(1)
Where:
Ta = Ambient Temperature
T = Temperature gradient between junction (silicon) and ambient = ja * P
P = Power
ja = Junction to ambient of package. ja numbers are located in the "Package Thermal Characteristics"
section below.
Package Thermal Characteristics
The device junction-to-case thermal characteristic is
jc, and the junction-to-ambient air characteristic is
ja. The thermal characteristics for ja are shown with two different air flow rates. jc is provided for reference.
The maximum junction temperature is 150
C.
The maximum power dissipation allowed for eX devices is a function of
ja. A sample calculation of the
absolute maximum power dissipation allowed for a TQFP 100-pin package at commercial temperature
and still air is as follows:
