Thermal shut-down
The presence of a thermal limiting circuit offers the following advantages:
an overload on the output (even if it is permanent), or an excessive ambient temperature
can be easily withstood.
the heatsink can have a smaller factor of safety compared with that of a conventional circuit.
There is no device damage in the case of excessive junction temperature: all happens is
that P
The maximum allowable power dissipation depends upon the size of the external heatsink
(i.e. its thermal resistance);
temperature for different thermal resistance.

Loudspeaker protection
The TDA7360 guarantees safe operations even for the loudspeaker in case of accidental
short-circuit.
Whenever a single OUT to GND, OUT to V
switched OFF so limiting dangerous DC current flowing through the loudspeaker.
