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 "stand-by out" and "diag. enable" commands are both given through a single programming step, the pulse takes place first (power stage still in stand-by 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.

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: Figure 22. Short circuit detection thresholds S.C. to GND x Normal Operation x S.C. to Vs 0V 1.2V 1.8V VS-1.8V VS-1.2V D01AU1253 VS 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. Load detection thresholds - high gain setting S.C. across Load x Normal Operation x Open Load 0V 0.5 1.5 45 85 AC00060 Infinite 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.

Short to gnd Short to VS Short across the speaker Output offset detection The following additional features are provided: The TDA7564B 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. 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 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). 2. - - - 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. 4.4 AC diagnostic It is targeted at detecting accidental disconnection of tweeters in 2-way speaker and, more in general, presence of capacitive (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, and it is enabled by setting (IB2-D2) = 1. Two different detection levels are available: - High current threshold IB2 (D7) = 0 Iout > 500mApk = normal status Iout < 250mApk = open tweeter Low current threshold IB2 (D7) = 1 Iout > 250mApk = normal status Iout < 125mApk = 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 IB2(D7)=0 (higher than 250mApk with IB2(D7)=1) in normal conditions and lower than 250mApk with IB2(D7)=0 (lower than 125mApk with IB2(D7)=1) 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 17/34 Diagnostics functional description TDA7564B This feature is disabled if any overloads leading to activation of the short-circuit protection occurs in the process.

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). 5.1 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. 19/34 Thermal protection TDA7564B 6 Thermal protection Thermal protection is implemented through thermal foldback (Figure 29). 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 29. Thermal foldback diagram Vout TH. WARN. TH. WARN. TH.

AC test: feed h.f. tone -- AC diag enable (write) --- wait > 3 cycles --- I2C read (repeat I2C reading until tweeter-off message disappears). Offset test: Device in play (no signal) -- offset enable - 30ms - I2C reading (repeat I2C reading until high-offset message disappears). 20/34 TDA7564B Fast muting 7 Fast muting The muting time can be shortened to less than 1.5ms 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. 21/34 I2C Bus interface TDA7564B 8 I2C Bus interface Data transmission from microprocessor to the TDA7564B 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). 8.1 Data validity As shown by Figure 30, 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. 8.2 Start and stop conditions As shown by Figure 31 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. 8.3 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. 8.4 Acknowledge The transmitter* puts a resistive high level on the SDA line during the acknowledge clock pulse (see Figure 32). The receiver** the acknowledges has to pull-down (low) the SDA line during the acknowledge clock pulse, so that the SDA line is stable low during this clock pulse. * Transmitter - - - - master (P) when it writes an address to the TDA7564B slave (TDA7564B) when the P reads a data byte from TDA7564B slave (TDA7564B) when the P writes an address to the TDA7564B master (P) when it reads a data byte from TDA7564B ** Receiver Figure 30.
