STK416-090-E no. a1621-9/12 [thermal design example for STK416-090-E (r l = 8 )] the thermal resistance, c-a, of the heat sink for total power dissipation, pd, within the hybrid ic is determined as follows. condition 1: the hybrid ic substrate temperature, tc, must not exceed 125 c. pd c-a + ta < 125 c ................................................................................................. (1) ta: guaranteed ambient temperature for the end product condition 2: the junction temper ature, tj, of each power tr ansistor must not exceed 150 c. pd c-a + pd/n j-c + ta < 150 c .......................................................................... (2) n: number of power transistors j-c: thermal resistance per power transistor however, the power dissipation, pd, for the power transistors shall be allocated equally among the number of power transistors. the following inequalities result from solving equations (1) and (2) for c-a. c-a < (125 ? ta)/pd ...................................................................................................... (1)' c-a < (150 ? ta)/pd ? j-c/n ........................................................................................ (2)' values that satisfy these two inequalities at the same time represent the required heat sink thermal resistance. when the following specifications have been stipulated, th e required heat sink thermal resistance can be determined from formulas (1)' and (2)'. ? supply voltage v h , v l ? load resistance r l ? guaranteed ambient temperature ta [example] when the ic supply voltage, v h = 38v, v l = 27v and r l is 8 , the total power dissipation, pd, within the hybrid ic, will be a maximum of 91w at 1khz for a co ntinuous 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 45.0w (when 1/8p o max. = 6.25w, p o max. = 50w). 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 2.1 c/w. therefore, the required heat sink thermal resistance for a guaranteed ambient temperature, ta, of 50 c will be as follows. from formula (1)' c-a < (125 ? 50)/45.0 < 1.67 from formula (2)' c-a < (150 ? 50)/45.0 ? 2.1/6 < 1.87 therefore, the value of 1.67 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.

STK416-090-E no. a1621-11/12 a protection application circuit of stk416-10 0sr consists of each block of (1)-(4). (1)stand-by control circuit part (2)load short detection part (3)latch-up circuit part (4)dc voltage protection part 1) stand-by control circuit part about #17 pin reference voltage vst. <1> operation mode the sw transistor of pre-driver ic is turned on at vst 2.5v, and the amplifier becomes operation mode. ex) at vst (min) = 2.5v vst = (*2) ist + 0.6v 2.5v=4.7k ist + 0.6v, i1 0.40ma <2> stand-by mode the sw transistor of pre-driver ic is turned off at vst 0.6v (typ 0v), and the amplifier becomes stand-by mode. ex) at vst = 0.6v vst = (*2) ist+0.6v 0.6v = 4.7k ist + 0.6v, i1 0ma (*1) resistance for restriction please set r1 for the voltage (vst) of the stand-by term inal to become ratings (+2.5v to 5.5v (typ 3.0v)). (*2) please supply the stand-by contro l voltage by the microcomputer etc. (*3) the limitation resistance is built into hybrid ic internal (#17pin) and 4.7k is built into. 2) load short detection part please refer to the attached paper (rl short prot ect explanation) for the operation explanation. tr1 (or tr2) doesn't move by normal operation. because, point.b - point.c < 0.6v. therefore load short detection part doesn't operate. but, when a load short-circuited, tr1 (or tr2) operate (point.b - point.c > 0.6v), and an electri c current ?i2? flows. 3) latch-up circuit part when i2 was supplied to latch-up circuit, tr3 operate. vst becomes stand-by mode (0v) when tr3 operates (i3 flows), the power amplifier is protected. stand-by mode is maintained when once tr3 operates because tr3 and tr4 compose the thyristor. it is necessary to make the stand-by control voltage (*2) l (0v) once to release stand-by mode and to make the power amplifier operate again. after, when stand-by control (*2) is retu rned to h (ex, +5v), it operates again. (*4) i3 is changed depending on the power-supply voltage (-v cc ). please set resistance (r2) to become i1 < i3 by the following calculation types. i1 i3=v cc /r2 4) dc offset protection part dc offset protection works at applying vdc (+), vdc (-) 0.5v (typ) to ?out ch1? or ?out ch2?, then hic will shutdown (stand-by mode). it is necessary to make the stand-by control voltage (*2) l (0v) once to release stand-by mode. the power amplifier operates again after stand- by control (*2) return to h (ex, +5v). please set the protection level by the resistance of ?82k ?. moreover, please set the time constant by ?22 //22 ? so as not to mis-detect it when the audio signal is output.
