Based on thermal characteristics of the package and with reference to the power
consumption figures provided in the next tables and diagrams, the following product
classification can be proposed. In any case, the exact power consumption of the device
inside the application must be computed according to different working conditions, thermal
profiles, real thermal resistance of the system (including printed circuit board or other
substrata) and I/O activity.
