BUILT-IN PROTECTION SYSTEMS
Thermal Shut-down
The 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.
