Description

The TDA7563A is a new BCD technology Quad
Bridge type of car radio amplifier in Flexiwatt27 &
PowerSO36 packages specially intended for car
radio applications.
Thanks to the DMOS output stage the TDA7563A
has a very low distortion allowing a clear powerful
sound. Among the features, its superior efficiency
performance coming from the internal exclusive
structure, makes it the most suitable device to
simplify the thermal management in high power sets.
The dissipated output power under average
listening condition is in fact reduced up to 50%
when compared to the level provided by
conventional class AB solutions.
This device is equipped with a full diagnostics
array that communicates the status of each
speaker through the I2 C bus.

TDA7563A Diagnostics functional description
3 Diagnostics functional description
3.1 Turn-on diagnostic

It is activated at the turn-on (standby out) under I2 C bus request. Detectable output faults
are: Short to GND Short to Vs Short across the speaker Open speaker o verify if any of the above misconnections are in place, a subsonic (inaudible) current
pulse (Figure 19) is internally generated, sent through the speaker(s) and sunk back.The
Turn On diagnostic status is internally stored until a successive diagnostic pulse is
requested (after a I2 C reading).
If the "standby out" and "diagnostic enable" commands are both given through a single
programming step, the pulse takes place first (power stage still in standby mode, low,
outputs = high impedance).
Afterwards, when the amplifier is biased, the PERMANENT diagnostic takes place. The
previous Turn On state is kept until a short appears at the outputs.
Figure 19. Turn-on diagnostic: working principle

Figure 20 and 21 show SVR and OUTPUT waveforms at the turn-on (standby out) with and
without TURN-ON DIAGNOSTIC.
Diagnostics functional description TDA7563A
Figure 20. SVR and output behavior (case 1: without turn-on diagnostic)
Figure 21. SVR and output pin behavior (case 2: with turn-on diagnostic)

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
26 dB to 12 dB gain setting. They are as follows:TDA7563A
Figure 22. Thresholds for short to GND/VS
DocID14407 Rev 5 15/35
TDA7563A Diagnostics functional description

Concerning SHORT ACROSS THE SPEAKER / OPEN SPEAKER, the threshold varies
from 26 dB to 12 dB gain setting, since different loads are expected (either normal speaker's
impedance or high impedance). The values in case of 26 dB gain are as follows:
Figure 23. Thresholds for short across the speaker/open speaker

If the Line-Driver mode (Gv= 12 dB and Line Driver Mode diagnostic = 1) is selected, the
same thresholds will change as follows:
Figure 24. Thresholds for line-drivers
3.2 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 TDA7563A has 2 operating statuses: 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 (Figure 25).
Restart takes place when the overload is removed.
2. DIAGNOSTIC mode. It is enabled via I2 C bus and self activates if an output overload
(such to cause the intervention of the short-circuit protection) occurs to the speakers
outputs. Once activated, the diagnostics procedure develops as follows (Figure 26): To avoid momentary re-circulation spikes from giving erroneous diagnostics, a
check of the output status is made after 1ms: if normal situation (no overloads) is
detected, the diagnostic is not performed and the channel returns back active. Instead, if an overload is detected during the check after 1 ms, then a diagnostic
cycle having a duration of about 100 ms is started. After a diagnostic cycle, the audio channel interested by the fault is switched to
RESTART mode. The relevant data are stored inside the device and can be read
by the microprocessor. When one cycle has terminated, the next one is activated
Diagnostics functional description TDA7563A
16/35 DocID14407 Rev 5
by an I2 C reading. This is to ensure continuous diagnostics throughout the car-
radio operating time. To check the status of the device a sampling system is needed. The timing is
chosen at microprocessor level (over half a second is recommended).
Figure 25. Restart timing without diagnostic enable (permanent) - Each 1ms time, a
sampling of the fault is done
Figure 26. Restart timing with diagnostic enable (permanent)
DocID14407 Rev 5 17/35
TDA7563A Output DC offset detection Output DC offset detection

Any DC output offset exceeding ± 2 V are signalled out. This inconvenient might occur as a
consequence of initially defective or aged and worn-out input capacitors feeding a DC
component to the inputs, so putting the speakers at risk of overheating.
This diagnostic has to be performed with low-level output AC signal (or Vin = 0).
The test is run with selectable time duration by microprocessor (from a "start" to a "stop"
command): START = Last reading operation or setting IB1 - D5 - (OFFSET enable) to 1 STOP = Actual reading operation
Excess offset is signalled out if it is persistent for all the assigned testing time. This feature is
disabled if any overload leading to activation of the short-circuit protection occurs in the
process.
4.1 AC diagnostic

It is targeted at detecting accidental disconnection of tweeters in 2-way speaker and, more
in general, presence of capacitively (AC) coupled loads. 
This diagnostic is based on the notion that the overall speaker's impedance (woofer +
parallel tweeter) will tend to increase towards high frequencies if the tweeter gets
disconnected, because the remaining speaker (woofer) would be out of its operating range
(high impedance). The diagnostic decision is made according to peak output current
thresholds, as follows:
Iout > 500 mApk = NORMAL STATUS
Iout < 250 mApk = OPEN TWEETER o correctly implement this feature, it is necessary to briefly provide a signal tone (with the
amplifier in "play") whose frequency and magnitude are such as to determine an output
current higher than 500 mApk in normal conditions and lower than 250 mApk should the
parallel tweeter be missing.
The test has to last for a minimum number of 3 sine cycles starting from the activation of the
AC diagnostic function IB2) up to the I2 C reading of the results (measuring period). To
confirm presence of tweeter, it is necessary to find at least 3 current pulses over 500 mA
over all the measuring period, else an "open tweeter" message will be issued.
The frequency / magnitude setting of the test tone depends on the impedance
characteristics of each specific speaker being used, with or without the tweeter connected
(to be calculated case by case). High-frequency tones (> 10 kHz) or even ultrasonic signals
are recommended for their negligible acoustic impact and also to maximize the impedance
module's ratio between with tweeter-on and tweeter-off.
Figure 27 shows the Load Impedance as a function of the peak output voltage and the
relevant diagnostic fields. 
This feature is disabled if any overload leading to activation of the short-circuit protection
occurs in the process.

4.2 Multiple faults

When more misconnections are simultaneously in place at the audio outputs, it is
guaranteed that at least one of them is initially read out. The others are notified after
successive cycles of I2 C reading and faults removal, provided that the diagnostic is enabled.
This is true for both kinds of diagnostic (Turn on and Permanent).
The table below shows all the couples of double-fault possible. It should be taken into
account that a short circuit with the 4 ohm speaker unconnected is considered as double
fault.
Table 5. Double fault table for turn on diagnostic

S. GND (so) / S. GND (sk) in the above table make a distinction according to which of the 2
outputs is shorted to ground (test-current source side= so, test-current sink side = sk). More
precisely, in Channels LF and RR, so = CH+, sk = CH-; in Channels LR and RF, so = CH-,
sk = CH+.
In Permanent Diagnostic the table is the same, with only a difference concerning Open
Load(*), which is not among the recognizable faults. Should an Open Load be present
during the device's normal working, it would be detected at a subsequent Turn on
Diagnostic cycle (i.e. at the successive Car Radio Turn on).
