Flexiwatt27 PowerSO36 Flexiwatt27
(Horizontal)
(Slug up)
Description
The TDA7563B is a new BCD technology quad
bridge type of car radio amplifier in Flexiwatt27
package specially intended for car radio
applications.
Thanks to the DMOS output stage the TDA7563B
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 I
2
C bus.

4.1 Turn-on diagnostic
It is activated at the turn-on (standby out) under I2C bus request. Detectable output faults
are:
● Short to GND
● Short to Vs
● Short across the speaker
● Open speaker
To 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 I
If the "standby out" and "diag. 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.

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:

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:

4.2 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 TDA7563B 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 (Figure 25).
Restart takes place when the overload is removed.
2. Diagnostic mode. It is enabled via I
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 by
2
an I
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).

TDA7563B Diagnostics functional description
4.3 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 persistent throughout the assigned testing time. This feature
is disabled if any overloads leading to activation of the short-circuit protection occurs in the
process.
4.4 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
To correctly implement this feature, it is necessary to briefly provide a signal tone (with the
amplifier in "play") whose frequency and magnitude are such to determine an output current
higher than 500 mApk with 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 < D2 > 0 up to the I
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 overloads leading to activation of the short-circuit protection
occurs in the process.

TDA7563B Multiple faults
5 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 I
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.

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).

Thermal protection TDA7563B
6 Thermal protection
Thermal protection is implemented through thermal foldback (Figure 28).
Thermal foldback begins limiting the audio input to the amplifier stage as the junction
temperatures rise above the normal operating range. This effectively limits the output power
capability of the device thus reducing the temperature to acceptable levels without totally
interrupting the operation of the device.
The output power will decrease to the point at which thermal equilibrium is reached.
Thermal equilibrium will be reached when the reduction in output power reduces the
dissipated power such that the die temperature falls below the thermal foldback threshold.
Should the device cool, the audio level will increase until a new thermal equilibrium is
reached or the amplifier reaches full power. Thermal foldback will reduce the audio output
level in a linear manner.
Three thermal warning are available through the I

6.1 Fast muting
The muting time can be shortened to less than 1.5 ms by setting (IB2) D5 = 1. This option
can be useful in transient battery situations (i.e. during car engine cranking) to quickly
turnoff the amplifier for avoiding any audible effects caused by noise/transients being
injected by preamp stages. The bit must be set back to “0” shortly after the mute transition.

3b - Turn-off of the power amplifier
Start Address byte with D0 = 0 ACK IB1 ACK IB2 ACK STOP
X0XXXXXX XXX0XXXX
4 - Offset detection procedure enable
Start Address byte with D0 = 0 ACK IB1 ACK IB2 ACK STOP
XX1XX11X XXX1XXXX
5 - Offset detection procedure stop and reading operation (the results are valid only for the
offset detection bits (D2 of the bytes DB1, DB2, DB3, DB4)
.
Start Address byte with D0 = 1 ACK DB1 ACK DB2 ACK DB3 ACK DB4 ACK STOP
● The purpose of this test is to check if a D.C. offset (2V typ.) is present on the outputs,
produced by input capacitor with anomalous leakage current or humidity between pins.
● The delay from 4 to 5 can be selected by software, starting from 1ms
