docid025642 rev 4 17/36 TDA75616LV diagnostics functional description 35 4.3 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 > 500 mapk = normal status iout < 250 mapk = open tweeter ? low current threshold ib2 (d7) = 1 iout > 250 mapk = normal status iout < 125 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 as to determine an output current higher than 500 mapk with ib2(d7) = 0 (higher than 250 mapk with ib2(d7) = 1) in normal conditions and lower than 250 mapk with ib2(d7) = 0 (lower than 125 mapk 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) up to the i 2 c reading of the results (measuring period). to confirm presence of tweeter, it is necessary to find at least 3 current pulses over the above threadless 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 13 and 14 shows the load impedance as a function of the peak output voltage and the relevant diagnostic fields. it is recommended to keep output voltage always below 8 v (high threshold case) or 4 v (low threshold case) to avoid the circuit to be saturated (causing wrong detection cases). this feature is disabled if any overloads leading to activation of the short-circuit protection occurs in the process.

docid025642 rev 4 19/36 TDA75616LV output dc offset detection 35 5 output dc offset detection the TDA75616LV can detect any dc output offset exceeding 2 v. 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. every time the power amplifier switches on, the ssr automatically mutes the device in case of offset. in play mode, the offset is signalled out on i 2 c bus. 5.1 offset detection and mute at start-up, ssr (speaker safety routine) TDA75616LV embeds a speaker safety routine in order to protect the speakers in case of big output offset. this protection mechanism can automatically mute the device within 40 ms when it detects an offset bigger than 2 v at the output. no external circuit is required for this feature. the ssr requires the mcu to turn on the audio power amplifier in a proper sequence. the mcu should at first turn on the device in mute condition and, after a suitable time to completely power on the device, which is about 1s, send a play command to it and make sure there is no signal applied to any of the inputs for at least 100 ms. the ssr can be enabled acting on ib2-d0 bit. see figure 15 . the power amplifier switches on and no input signal is applied. after 1 s the svr is fully charged and the output dc voltage is set. the mcu sends the play command and the offset, on all the channels, is checked. in case the detected offset is null or, anyhow, lower than 2 v, the power amplifier is kept alive and the audio signal can be applied after 100 ms. figure 15. power on sequence with a detected offset lower than 2 v
output dc offset detection TDA75616LV 20/36 docid025642 rev 4 look at the figure 16 . the power amplifier switches on and no input signal is applied. after 1 s the svr is fully charged and the output dc voltage is set. the mcu sends the play command and the offset, on all the channels, is checked. if an offset bigger than 2 v is detected, the power amplifier is switched off within 40 ms. figure 16. power on sequence with a detected offset higher than 2 v this action is pointed out on the i 2 c bus, bit db2-d6. this flag is seen by the microcontroller which can take proper actions. a standby command (hardware or by i 2 c) can reset the power amplifier 5.2 offset detection in normal operation it is a diagnostics function which 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 of all the assigned testing time. this feature is disabled if any overloads leading to activation of the short-circuit protection occurs in the process.
docid025642 rev 4 21/36 TDA75616LV multiple faults 35 6 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 2 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 speaker unconnected is considered as double fault. 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). 6.1 faults availability all the results coming from i 2 c 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 cycle (turn-on, permanent, offset) is activated again after any i 2 c reading operation. so, when the micro reads the i 2 c, 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 i 2 c. the short to gnd is still present in bytes, because it is the result of the previous cycle. if another i 2 c reading operation occurs, the bytes do not show the short). in general to observe a change in diagnostic bytes, two i 2 c reading operations are necessary. table 6. double fault table for turn on diagnostic s. gnd s. vs s. across l. open l. s. gnd s. gnd s. vs + s. gnd s. gnd s. gnd s. vs / s. vs s. vs s. vs s. across l. / / s. across l. n.a. open l. / / / open l.

thermal protection TDA75616LV 22/36 docid025642 rev 4 7 thermal protection thermal protection is implemented through thermal foldback ( figure 17 ). 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 2 c bus data. after thermal shut down threshold is reached, the cd could toggle (as shown in figure 17 ) or stay low, depending on signal level. figure 17. thermal foldback diagram 7.1 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 to avoid 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. 4j # 4(3( 34!24 4(3( %.$ 6out 4(7!2. /. 4j # 6out 4j # 3$ withsameinput signal 4 3$ #$out 4( 7! 2. /. 4(7!2. /. *$3*36
