4.1.7
Thermal shut-down
The presence of a thermal limiting circuit offers the following advantages:
1.
an overload on the output (even if it is permanent), or an excessive ambient
temperature can be easily withstood.
2.
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
that happens is that Po (and therefore Ptot) and Id are reduced.
The maximum allowable power dissipation depends upon the size of the external heatsink
(i.e. its thermal resistance); Figure 37 shows the power dissipation as a function of ambient
temperature for different thermal resistance.
4.1.8
Loudspeaker protection
The circuit offers loudspeaker protection during short circuit for one wire to ground.
