Solving equations 1 and 2 for K gives:
Eqn. 3
where K is a constant pertaining to the particular part. K can be determined from Equation 3 by measuring P
D
(at equilibrium)
for a known T
A
. Using this value of K, the values of P
D
and T
J
can be obtained by solving Equation 1 and Equation 2 iteratively
for any value of T
A
.
4.3 ESD protection
4.4 Static latch-up (LU)
Two complementary static tests are required on six parts to assess the latch-up performance:
A supply over voltage is applied to each power supply pin.
A current injection is applied to each input, output, and configurable I/O pin.
These tests are compliant with the EIA/JESD 78 IC latch-up standard.

A device is defined as a failure if after exposure to ESD pulses the device no longer meets
the device specification requirements. Complete DC parametric and functional testing is
performed per applicable specification at room temperature followed by hot temperature,
unless specified otherwise in the device specifications provided in this document.
