Junction Temperature (TJ)
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 , shown below, can be used to calculate
junction temperature.
Junction Temperature =
ΔT + T
a (1)
EQ 1
Where:
Ta = Ambient Temperature
ΔT = Temperature gradient between junction (silicon) and ambient
ΔT = θ
ja * P (2)
P = Power
θ
ja = Junction to ambient of package. θja numbers are located in Table 1-21 on page 1-26.
