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 I2C bus.

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 I2C 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.

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 I2C 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 Doc ID 14407 Rev 2 15/35 Diagnostics functional description TDA7563A by an I2C reading. This is to ensure continuous diagnostics throughout the carradio 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.

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. 4.1 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 > 500mApk = NORMAL STATUS Iout < 250mApk = 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 500mApk with in normal conditions and lower than 250mApk 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>) up to the I2C reading of the results (measuring period). To confirm presence of tweeter, it is necessary to find at least 3 current pulses over 500mA 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. Doc ID 14407 Rev 2 17/35 Output DC offset detection TDA7563A Figure 27.

The others are notified after successive cycles of I2C 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.

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). 18/35 Doc ID 14407 Rev 2 TDA7563A 4.3 Output DC offset detection Faults availability All the results coming from I2C bus, by read operations, are the consequence of measurements inside a defined period of time. If the fault is stable throughout the whole period, it will be sent out. To guarantee always resident functions, every kind of diagnostic cycles (Turn on, Permanent, Offset) will be reactivate after any I2C reading operation. So, when the micro reads the I2C, a new cycle will be able to start, but the read data will come from the previous diag. cycle (i.e. The device is in Turn On state, with a short to Gnd, then the short is removed and micro reads I2C. The short to Gnd is still present in bytes, because it is the result of the previous cycle. If another I2C reading operation occurs, the bytes do not show the short). In general to observe a change in Diagnostic bytes, two I2C reading operations are necessary. Doc ID 14407 Rev 2 19/35 Thermal protection 5 TDA7563A 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 I2C bus data. Figure 28.

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. Doc ID 14407 Rev 2 21/35 I2C bus TDA7563A 7 I2C bus 7.1 I2C programming/reading sequences A correct turn on/off sequence respectful of the diagnostic timings and producing no audible noises could be as follows (after battery connection): TURN-ON: PIN2 > 7V --- 10ms --- (STANDBY OUT + DIAG ENABLE) --- 500 ms (min) --MUTING OUT TURN-OFF: MUTING IN --- 20 ms --- (DIAG DISABLE + STANDBY IN) --- 10ms --- PIN2 = 0 Car Radio Installation: PIN2 > 7V --- 10ms DIAG ENABLE (write) --- 200 ms --- I2C read (repeat until All faults disappear). OFFSET TEST: Device in Play (no signal) -- OFFSET ENABLE - 30ms - I2C reading (repeat I2C reading until high-offset message disappears). 7.2 I2C bus interface Data transmission from microprocessor to the TDA7563A and vice versa takes place through the 2 wires I2C BUS interface, consisting of the two lines SDA and SCL (pull-up resistors to positive supply voltage must be connected). 7.3 Data validity As shown by Figure 29, the data on the SDA line must be stable during the high period of the clock. The HIGH and LOW state of the data line can only change when the clock signal on the SCL line is LOW. 7.4 Start and stop conditions As shown by Figure 30 a start condition is a HIGH to LOW transition of the SDA line while SCL is HIGH. The stop condition is a LOW to HIGH transition of the SDA line while SCL is HIGH. 7.5 Byte format Every byte transferred to the SDA line must contain 8 bits. Each byte must be followed by an acknowledge bit. The MSB is transferred first. 22/35 Doc ID 14407 Rev 2 TDA7563A 7.6 I2C bus Acknowledge The transmitter(*) puts a resistive HIGH level on the SDA line during the acknowledge clock pulse (see Figure 31).
