The junction temperature j, can be calculated using the following equation: j = P*Ja + a
Where,
P = Power
Ja = Junction to ambient temperature (Jc + Ca
)
a = Ambient temperature (70 °C)
The case temperature c, can be calculated using the following equation: c = P*Ca + a
where,
P = Power
Ca = Case to ambient temperature
a = Ambient temperature (70 °C)
Note
15. Do not power I/O with chip power off.
