Preliminary data sheet
8.4.1 Thermal Foldback (FT)
8.4 Protections
Table 5
For device synchronization see
Table 5.
The following protections are implemented in the TDA8933B:
The behavior of the device under the different fault conditions differs according to the
protection activated and is described in the following sections.
If the junction temperature of the TDA8933B exceeds the threshold level (T
gain of the amplifier is decreased gradually to a level where the combination of
dissipation (P) and the thermal resistance from junction to ambient (R
junction temperature of around the threshold level.
