Device thermal performances
All the figures given in this section are obtained assuming that the QFN device is cooled
down only by conduction through the package thermal pad (no convection mode
considered).
The temperature is monitored at the package back-side interface (Tcase) as shown below.
The system maximum temperature must be adjusted in order to guarantee that Tcase
remains below than the maximum value specified in the next table. So, the system PCB must
be designed to comply with this requirement.
A derating must be applied on the dissipated power if the Tcase temperature can not be
maintained below than the maximum temperature specified (see the curve Pdiss. Max) in
order to guarantee the nominal device life time (MTTF).
