    11.7 Power Considerations
    The average chip junction temperature, TJ, in °C can be obtained from:
    TJ = TA + (PD x θJA)
    (1)
    Where:
    TA = ambient temperature in °C
    θ
    JA = package thermal resistance, junction to ambient in °C/W
    PD = PINT + PI/O
    PINT = ICC × VCC = chip internal power dissipation
    PI/O = power dissipation on input and output pins (user-determined)
    For most applications, PI/O < PINT and can be neglected.
    Ignoring PI/O, the relationship between PD and TJ is approximately:
    (2)
    Solving equations (1) and (2) for K gives:
    = PD x (TA + 273°C) + θJA x (PD)
    2
    (3)
    where K is a constant pertaining to the particular part. K can be
    determined from equation (3) by measuring PD (at equilibrium) for a
    known TA. Using this value of K, the values of PD and TJ can be obtained
    by solving equations (1) and (2) iteratively for any value of TA.
    PD =
    TJ + 273°C
    K
