10.2 THERMAL CHARACTERISTICS
10.3 POWER CONSIDERATIONS
The average chip-junction temperature, T J , in C can be obtained from:
For most applications, P I/O < 0.3*P INT and can be neglected.
An approximate relationship between P D and T J (if P I/O is neglected) is:
10-2
where:
T A =
P D =
PINT =
P I/O =
JA =
T J = T A + (P D • JA )
P D = K
Solving Equations (1) and (2) for K gives:
K = P D • (T A + 273 C) + JA • P D
