The average chip-junction temperature (TJ) in °C can be obtained from:
TJ = TA + (PD × θJA)
Eqn. 1
where:
—TA = Ambient temperature, °C
θJA = Package thermal resistance, junction-to-ambient, °C/W
—PD = Pint + PI/O
—Pint = IDD × VDD, Watts — chip internal power
—PI/O = Power dissipation on input and output pins — user-determined
For most applications, PI/O << Pint and can be neglected. An approximate relationship between PD and TJ (if PI/O is neglected)
is:
PD = K ÷ (TJ + 273°C)
Eqn. 2
Solving Equation 1 and Equation 2 for K gives:
K = PD × (TA + 273°C) + θJA × (PD)
2
Eqn. 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 Equation 1 and Equation 2 iteratively
for any value of TA.

ESD Protection and Latch-Up Immunity
Although damage from electrostatic discharge (ESD) is much less common on these devices than on early CMOS circuits,
normal handling precautions should be used to avoid exposure to static discharge. Qualification tests are performed to ensure
that these devices can withstand exposure to reasonable levels of static without suffering any permanent damage.
All ESD testing is in conformity with AEC-Q100 Stress Test Qualification for Automotive Grade Integrated Circuits. During
the device qualification ESD stresses were performed for the human body model (HBM), the machine model (MM) and the
charge device model (CDM).
