BUILD-IN PROTECTION SYSTEMS
Thermal shut-down
The presence of a thermal limiting circuit offers
the followingadvantages:
1) an overload on the output (even if it is perma-
nent), 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 devicedamage in the case
of excessive junction temperature; all that
happens is that P
O
( and therefore Ptot) and
I
O
are reduced. The maximum allowable
power dissipation depends upon the size of
the external heatsink (i.e. its thermal resis-
tance); Figure 12 shows this dissipable power
as a function of ambient temperature for dif-
ferent thermal resistance.
Short circuit (AC Conditions)
The TDA7262 can withstand accidental short cir-
cuits across the speaker made by a wrong con-
nection during normal playoperation.
MOUNTING INSTRCTIONS
The power dissipated in the circuit must be re-
moved by adding an external heatsink.
Thanks to the MULTIWATT package attaching
the heatsink is very simple, a screw or a com-
pression spring (clip) being sufficient. between
the heatsink and the package it is better to insert
a layer of silicon grease, to optimize the thermal
contact; no electrical isolation is needed between
the twosurfaces.
