application suggestion TDA2004R 12/17 doc id 17614 rev 1 3 application suggestion the recommended values of the components are those shown on application circuit of figure 2 . different values can be used; the following table can help the designer. 3.1 built-in protection systems 3.1.1 load dump voltage surge the TDA2004R has a circuit which enables it to withstand voltage pulse train, on pin 9, of the type shown in figure 20 . if the supply voltage peaks to more than 40 v, then an lc filter must be inserted between the supply and pin 9, in order to assure that the pulses at pin 9 will be held within the limits shown. a suggested lc network is shown in figure 19 . with this network, a train of pulses with amplitude up to 120 v and width of 2 ms can be applied at point a. this type of protection is on when the supply voltage (pulse or dc) exceeds 18 v. for this reason the maximum operating supply voltage is 18 v. table 5. recommended values of the component of the application circuit component recommended value purpose larger than smaller than r r1 120 k optimization of the output signal symmetry smaller p omax smaller p omax r2, r4 1 k closed loop gain setting (1) increase of gain decrease of gain r3, r5 3.3 decrease of gain increase of gain r6, r7 1 frequency stability danger of oscillation at high frequency with inductive load c1, c2 2.2 f input dc decoupling high turn-on delay high turn-on pop, higher low frequency cutoff. increase of noise c3 10 f ripple rejection increase of svr, increase of the switch-on time degradation of svr c4, c6 100 f bootstrapping - increase of distortion at low frequency c5, c7 100 f feedback input dc decoupling -- c8, c9 0.1 f frequency stability - danger of oscillation c10, c11 1000 to 2200 f output dc decoupling - higher low-frequency cut-off 1. the closed loop gain must be higher than 26 db.
TDA2004R application suggestion doc id 17614 rev 1 13/17 figure 19. suggested lc network circuit figure 20. voltage gain bridge configuration 3.1.2 short circuit (ac condition) the TDA2004R can withstand a permanent short- circuit from the output to ground caused by a wrong connection during normal working. 3.1.3 polarity inversion high current (up to 10 a) can be handled by the device with no damage for a longer period than the blow-out time of a quick 2 a fuse (normally connected in series with the supply). this feature is added to avoid destruction, if during fitting to the car, a mistake on the connection of the supply is made. 3.1.4 open ground when the ratio is in the on condition and the ground is accidentally opened, a standard audio amplifier will be damaged. on the TDA2004R protection diodes are included to avoid any damage. 3.1.5 inductive load a protection diode is provided to allow use of the TDA2004R with inductive loads. 3.1.6 dc voltage the maximum operating dc voltage for the TDA2004R is 18 v. however the device can withstand a dc voltage up to 28 v with no damage. this could occur during winter if two batteries are series connected to crank the engine. from supply line l = 2mh a c to pin 3000 f 16v v s (v) 40 t1 t1 = 50ms t2 = 1000ms t2 t 14.4
application suggestion TDA2004R 14/17 doc id 17614 rev 1 3.1.7 thermal shut-down the presence of a thermal limiting circuit offers the following advantages: 1. an overload on the output (even if it is permanent), or an excessive ambient temperature can be easily withstood. 2. the heatsink can have a smaller factor of safety compared with that of a conventional circuit. there is no device damage in the case of excessive junction temperature: all that happens is that p o (and therefore p tot ) and i d are reduced. the maximum allowable power dissipation depends upon the size of the external heatsink (i.e. its thermal resistance); figure 18 shows the power dissipation as a function of ambient temperature for different thermal resistance.
