Definition of product operating temperature
The product operating temperatures is used to monitor the
temperature of the product, and proper thermal conditions can
be verified by measuring the temperature at positions P1, P2
and P2. The temperature at these positions (TP1, TP2 , TP3)
should not exceed the maximum temperatures in the table
below. The number of measurement points may vary with
different thermal design and topology. Temperatures above
maximum TP1, measured at the reference point P1 are not
allowed and may cause permanent damage.
