LV49157V no.a1567-15/30 power supply lowering protection circuit since the instable operation in the low voltage is prevented by using this circuit, after the voltage of the pvd pin is monitored and the voltage below the attack voltage (pvd = 8v typ.), amp is turned off. also, to prevent the instable operation when the voltage of the pvd pin is decreased by an y cause during operations, the attack voltage (pvd = 7v typ.) is set. the voltage of attack and recover has hysteresis (about 1v) to prevent on/off continuous action of the power supply lowering protection circuit. function image also, this ic is designed to turn off amp in the same seque nce that the mute is on as a pop noise measures when the plug of products are put off. over current protection circuit the over current protection circuit is a protection circuit * to protect the output dmos from the over current and corresponds to any mode of the po wer supply, gnd and a load short. the protection operation is performed when the current reaches the detection current value set out in ic and the output dmos is compulsorily turned off for about 20 sec. after compulsorily tuning off the output dmos, when the amp lifier is automatically reset in usual operation and the over current flows continuously, the protec tion operation is performed again. function image * the over current protection circuit is a function to avoi d the abnormal state like the output short-circuit temporarily. unfortunately, we cannot guarantee that ic is not destroyed.
LV49157V no.a1567-16/30 thermal protection circuit the LV49157V includes a thermal protection circuit to prevent damage to or destruction of the ic should abnormal internal heat generation occur. this means that should the ic junction temperature (tj) rise above about 175 c due to inadequate heat dissipation or other reason, the thermal protection circuit will operate to stop ic operation should the temperature rise further. if the temperature is reduced by lowering the input level or other means, the thermal protection circuit will recover automatically (about 105 c). function image * the thermal protection circuit is a function to avoid the abnormal state temporarily. unfortunately, we cannot guarantee that ic is not destroyed. recovery attack internal tsd det. pwm internal tsd det. pwm 150 200 180 100 130 90 70 40 50 60 80 110 110 110 160 170 190 junction temperature tj [ c] temperature (tj) rise hystsrisis shut down temperature (tj) fall shut down
LV49157V no.a1567-17/30 plc the plc (power level control) function is able to control the maximum index m odulation by setting a value of external plc resistance r1 voluntarily, and prevent a pwm signal from becoming the over modulation mode. in addition, this circuit can be use as output power limit circuit because the plc function can set the maximum index modulation voluntarily, and variable from 2w to 15w with output power linearly in the state that made the power supply voltage and load resistance fixation. because the plc function can se t the suitable rated output with the same power supply voltage/speaker regardless of screen size in flat screen te levisions by this, set can plan the commonization of the board. furthermore, the plc function can reduce abnormal noise in the hard clip so that output wave pattern becomes the soft clip when it limited output power. function image measuring condition vd = 15v, r l = 8 , l = 33 h (toko : a7502by-330m), c = 0.1uf,c l = 0.47 f,ta = 25 c setting example of the output power limit value * when it is used this function as output power limit, pl ease use the high-precision resistance such as the metal film resistor when precision of the electricity value is necessary. * the value of external plc resist ance r1 please connects more than 3k . * when it is changed a value of external plc resistance r1, please turn off an amplifier. r1 [k ] po@10% [w] 3.0 0.694 3.6 1.073 4.7 1.982 6.2 3.642 7.5 5.562 8.2 6.855 9.1 8.591 10 10.64 13 15.32 15 15.94 20 16.01 r1 -- p o @thd + n = 10% 0 14 16 10 12 8 4 6 2 18 010 8 6 4 21214161820 r1?k p o @thd + n = 10% ? w vd = 15v r l = 8 fin = 1khz thd + n = 10% 2ch-drive aes17 max. power half power min. power gnd plc r1 5 13 LV49157V
