Preliminary Electrical Characteristics

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 Characteristics
Although damage from static discharge 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 CDF-AEC-Q00 Stress Test Qualification for Automotive Grade Integrated Circuits.
(http://www.aecouncil.com/) This device was qualified to AEC-Q100 Rev E.
A device is considered to have failed if, after exposure to ESD pulses, the device no longer meets the device specification
requirements. Complete dc parametric and functional testing is performed per the applicable device specification at room
temperature followed by hot temperature, unless specified otherwise in the device specification.
