TDA7563PD

The information related to the outputs status is read and memorized at the end of the current pulse top. The
acquisition time is 100 ms (typ.). No audible noise is generated in the process. As for SHORT TO GND / Vs the
fault-detection thresholds remain unchanged from 30 dB to 16 dB gain setting. They are as follows:
Figure 22.
Concerning SHORT ACROSS THE SPEAKER / OPEN SPEAKER, the threshold varies from 30 dB to 16 dB
gain setting, since different loads are expected (either normal speaker's impedance or high impedance). The
values in case of 30 dB gain are as follows:
Figure 23.
If the Line-Driver mode (Gv= 16 dB and Line Driver Mode diagnostic = 1) is selected, the same thresholds will
change as follows:
Figure 24.
b) PERMANENT DIAGNOSTICS.
Detectable conventional faults are:
– SHORT TO GND
– SHORT TO Vs
– SHORT ACROSS THE SPEAKER
The following additional features are provided:
– OUTPUT OFFSET DETECTION
The TDA7563PD has 2 operating statuses:
1 RESTART mode. The diagnostic is not enabled. Each audio channel operates independently from each
other. If any of the a.m. faults occurs, only the channel(s) interested is shut down. A check of the output
status is made every 1 ms (fig. 25). Restart takes place when the overload is removed.
