thermal protection tda75610slv 24/42 docid025599 rev 5 6 thermal protection thermal protection is implemented through thermal foldback ( figure 33 ). thermal foldback begins limiting the audio input to the amplifier stage as the junction temperatures rise above the normal operating ra nge. this effectively limits the output power capability of the device thus re ducing the temperatur e to acceptable leve ls without totally interrupting the operation of the device. the output power will decrease to the point at which ther mal 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 in crease until a new th ermal equilibrium is reached or the amplif ier reaches full power. thermal foldback will reduce the audio output level in a linear manner. three thermal warnings are available through the i 2 c bus data. after thermal shut down threshold is reached, the cd could toggle (as shown in figure 33 ) or stay low, depending on signal level. figure 33. thermal foldback diagram 6.1 fast muting the muting time can be shorte ned to less than 1.5 ms by setting (ib2) d5 = 1. this option can be useful in transient battery situatio ns (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. /.

application suggestion tda75610slv 28/42 docid025599 rev 5 8.2 high efficiency introduction thanks to its operating principle, the tda7 5610slv obtains a substantial reduction of power dissipation from traditional class-ab amp lifiers without being affected by the massive radiation effects and complex circuitry nor mally associated with class-d solutions. the high efficiency operating principle is bas ed on the use of bridge structures which are connected by means of a power switch. in particular, as shown in figure 1 , ch1 is linked to ch2, while ch3 to ch4. the sw itch, controlled by a logic ci rcuit which senses the input signals, is closed at low volumes (output po wer steadily lower than 2.5 w) and the system acts like a "single bridge" with double load. in this case, the total power dissipation is a quarter of a double bridge. due to its structure, the highest efficiency le vel can be reached when symmetrical loads are applied on channels sharing the same switch. figure 38. high efficiency - basic structure when the power demand increases to more th an 2.5 w, the system behavior is switched back to a standard double bridge in order to guarantee the maximum output power, while in the 6 v start-stop devices the high efficiency mode is automatically disabled at low v cc (7.3 v 0.3 v). no need to re-program it when v cc goes back to normal levels. in the range 2-4 w (@ v cc = 14.4 v, r l = 4 ? ), with the high efficiency mode, the dissipated power gets up to 50 % less than the value obtained with the standard mode.
