STK433-040-E no. a1470-8/11 [example] when the ic supply voltage, v cc , is 24v and r l is 6 , the total power dissipation, pd, within the hybrid ic, will be a maximum of 41w at 1khz for a continuo us sine wave signal according to the pd-p o characteristics. for the music signals normally handled by audio amplifiers, a value of 1/8p o max is generally used for pd as an estimate of the power dissipation based on the type of continuous signal. (note that the factor used may differ depending on the safety standard used.) this is: pd 31.8w (when 1/8p o max. = 5.0w, p o max. = 40w). the number of power transistors in audio amplifier block of these hybrid ics, n, is 4, and the thermal resistance per transistor, j-c, is 4.2 c/w. therefore, the required heat sink thermal resistance for a guranteed ambient temperature, ta, of 50 c will be as follows. from formula (1)' c-a < (125 ? 50)/31.8 < 2.36 from formula (2)' c-a < (150 ? 50)/31.8 ? 4.2/4 < 2.09 therefore, the value of 2.09 c/w, which satisfies both of these formulae, is the required thermal resistance of the heat sink. note that this thermal design exampl e assumes the use of a constant-voltage power supply, and is therefore not a verified design for any particular user?s end product. stk433-000 series standby control, mu te control, load-short protection & dc offset protection application 2 3 4 5 6 7 8 9 10 11 12 13 14 1 15 ch1 out gnd +v cc -v cc stk433-000 series st-by 56k gnd ch2 in gnd ch1 in +v cc ch1 in ch1 nf ch2 in ch2 nf ch2 out ch1 out -v cc sub gnd +pre st-by ch1 out ch2 out -pre 0.22 /2w 6.8k 56k 6.8k 0.22 /2w 56k 56k load short protection circuit 22k 56k 1k 0.1 f 10k 100k (*4) r2 1k 33k 2k (*1) r1 ex) 5.1k 33 f / 10v 10k 10k 10k 2.2k v1 gnd ch2 out 82k 82k 100 k 22 f 22 f play mute st-by mute +5v +5v standby control mute control mute control h: single mute l: normal stand-by control (ex) h: operation mode (+5v) l: stand-by mode (0v) dc offset protection (*1) the voltage applied to the stand-by pin (#13) must not exceed the maximum rated value (vst max).

STK433-040-E no. a1470-9/11 stk433-000 series application explanation the protection circuit application for the stk433-000sr consists of the following blocks (blocks (1) to (4)). (1) standby control circuit block (2) load short-circuit detection block (3) latch-up circuit block (4) dc voltage protection block 1) standby control circuit block concerning pin 13 reference voltage vst <1> operation mode the switching transistor of the predriver ic turns on when the pin 13 reference voltage, vst, becomes greater than or equal to 2.5v, placing the amplifier into the operation mode. example: when vst (min.) = 2.5v i1 is approximately equal to 0.40ma since vst = (*2) ist + 0.6v 2.5v = 4.7k ist + 0.6v. <2> standby mode the switching transistor of the predriver ic turns off when the pin 13 reference voltage, vst, becomes lower than or equal to 0.6v (typ. 0v), placing the amplifier into the standby mode. example: when vst = 0.6v i1 is approximately equal to 0ma since vst = (*2) ist + 0.6v 0.6v = 4.7k ist + 0.6v. (*1) limiting resistor determine the value of r1 so that the voltage vst app lied to the standby pin (pin 13) falls within the rating (+2.5v to 5.5v (typ. 3.0v)). (*2) the standby control voltage must be supplied from the host including microcontrollers. (*3) a 4.7k limiting resistor is also incorporated inside the hybrid ic (at pin 13). 2 3 4 5 6 7 8 9 10 11 12 13 14 1 15 out ch1 stk433-000 series 56k i1 +v cc ch1 in ch1 nf ch2 in ch2 nf ch2 out(-) ch1 out(+) -v cc sub gnd +pre st-by ch1 out(-) ch2 out(+) -pre 0.22 /2w 6.8k 56k 6.8k 0.22 /2w 56k 56k (2) load short detection part 22k 56k 1k 0.1 f 10k 100k 1k 33k 2k (*1) r1 ex) 5.1k 33 f out ch2 82k 82k 100 k 22 f 22 f 1) stand-by control circuit part h: operation mode (+5v) l: stand-by mode (0v) point.b point.b point.c point.c tr1 tr2 stand-by circuit in pre driver ic sw transistor v be 4.7k (*3) stand-by control voltage vst (*4) r2 i2 i3 operate mode (vst off ) 2.5v stand-by mode (vst on ) < 0.6v (0v typ) (3) latch-up circuit part (4) dc offset protection tr4 tr5 tr3 tr5 tr6 -v cc
STK433-040-E no. a1470-10/11 2) load short-circuit detection block since the voltage between point b and point c is less than 0.6v in normal operation mode (v be < 0.6v) and tr1 (or tr2) is not activated, the load short-ci rcuit detection block does not operate. when a load short-circuit occurs, however, the voltage between point b and point c becomes larger than 0.6v, causing tr1 (or tr2) to turn on (v be > 0.6v), and current i2 to flows. 3) latch-up circuit block tr3 is activated when i2 is supplied to the latch-up circuit. when tr3 turns on and current i3 starts flowing, vst goes down to 0v (standby mode), protecting the power amplifier. since tr3 and tr4 configure a thyristor, once tr3 is activated, the ic is held in the standby mode. to release the standby mode an d reactivate the power amplifier, it is necessa ry to set the standby control voltage (*2) temporarily low (0v). subsequently, when the standby contro l is returned to high, the power amplifier will become active again. (*4) the i3 value varies depending on the supply voltage. determine the value of r2 using the formula below, so that i1 is equal to or less than i3. i1 i3 = v cc /r2 4) dc offset protection block the dc offset protection circuit is ac tivated when 0.5v (typ) voltage is applied to either "out ch1" or "out ch2," and the hybrid ic is shut down (standby mode). to release the ic from the standby mode and reactivate the power amplifier, it is necessary to set the standby control voltage temporarily low (0v). subsequently, when the standby control is returned to high (+5v, for example), the power amplifier will become active again. the protection level must be set using the 82k resistor. furthermore, the time constant must be determined using 22 //22 capacitors to prevent the amplifier from malfunctioning due to the audio signal. stk433-000 series btl application 2 3 4 5 67 8 9 10 11 12 13 14 1 15 +v cc -v cc stk433-000-e series out 10 0.1 3pf 56k 3pf gnd ch1 in 56k 470pf 2.2 +v cc ch1 in ch1 nf ch2 in ch2 nf ch2 out ch1 out -v cc sub gnd +pre st-by 100 100 stand-by control voltage vst ch1 out ch2 out -pre 100 /1w 3 0.22 4.7 3 /1w 0.1 /1w r l =8 56k 33 /1w 100
