BUILT-IN PROTECTION SYSTEMS
Thermal Shut-downThe presence of a thermal limiting circuit offers the
following advantages:
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 device damage in the case of exces-
sive junction temperature; all that happens is
that PO (and therefore PO) and IO are reduced.
Short Circuit (AC Conditions)The TDA7263SA can withstand accidental short
circuits across the speaker made by a wrong con-
nection during normal play operation.

HEAT SINK DIMENSIONING:In order to avoid the thermal protection intervention, that is placed approximatively at Tj = 150°C, it is important
the dimensioning of the Heat Sinker RTh (°C/W).
The parameters that influence the dimensioning are: Maximum dissipated power for the device (Pdmax) Max thermal resistance Junction to case (RTh j-c) Max. ambient temperature Tamb max Quiescent current Iq (mA)
Example:
VCC = 28V, Rload = 8ohm, RTh j-c = 3.5 °C/W , Tamb max = 50°C
Pdmax = (N° channels) ·
Pdmax = 2 · ( 4.9 ) + 1.9 = 11.3W

Clipwatt Assembling Suggestions The suggested mounting method of Clipwatt on external heat sink, requires the use of a clip placed as much
as possible in the plastic body center, as indicated in the example of figure 9.
A thermal grease can be used in order to reduce the additional thermal resistance of the contact between pack-
age and heatsink.
A pressing force of 7 - 10 Kg gives a good contact and the clip must be designed in order to avoid a maximum
contact pressure of 15 Kg/mm2 between it and the plastic body case.
As example , if a 15Kg force is applied by the clip on the package , the clip must have a contact area of 1mm2
at least.
