Condition 1: The hybrid IC substrate temperature, Tc, must not exceed 125°C. Pd × θc-a + Ta < 125°C ................................................................................................. (1) Ta: Guaranteed ambient temperature for the end product Condition 2: The junction temperature, Tj, of each power transistor must not exceed 150°C. Pd × θc-a + Pd/N × θj-c + Ta < 150°C .......................................................................... (2) N: Number of power transistors θj-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 θc-a. θc-a < (125 − Ta)/Pd ...................................................................................................... (1)' θc-a < (150 − Ta)/Pd − θj-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, the required heat sink thermal resistance can be determined from formulas (1)' and (2)' . • Supply voltage VCC • Load resistance RL • Guaranteed ambient temperature Ta No. A1247-7/11 STK433-030-E [Example] When the IC supply voltage, VCC, is ±21V and RL is 6Ω, the total power dissipation, Pd, within the hybrid IC, will be a maximum of 31W at 1kHz for a continuous sine wave signal according to the Pd-PO characteristics. For the music signals normally handled by audio amplifiers, a value of 1/8PO 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 ≈ 24.0W (when 1/8PO max. = 3.75W, PO max. = 30W). The number of power transistors in audio amplifier block of these hybrid ICs, N, is 4, and the thermal resistance per transistor, θj-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)' θc-a < (125 − 50)/24.0 < 3.13 From formula (2)' θc-a < (150 − 50)/24.0 − 4.2/4 < 3.12 Therefore, the value of 3.12°C/W, which satisfies both of these formulae, is the required thermal resistance of the heat sink. Note that this thermal design example assumes the use of a constant-voltage power supply, and is therefore not a verified design for any particular user’s end product.

(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 = 4.7kΩ × 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 = 4.7kΩ × IST + 0.6V. (*1) Limiting resistor Determine the value of R1 so that the voltage VST applied 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 4.7kΩ limiting resistor is also incorporated inside the hybrid IC (at pin 13). No. A1247-9/11 STK433-030-E 2) Load short-circuit detection block Since the voltage between point B and point C is less than 0.6V in normal operation mode (VBE < 0.6V) and TR1 (or TR2) is not activated, the load short-circuit 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 (VBE > 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 and reactivate the power amplifier, it is necessary to set the standby control voltage (*2) temporarily low (0V). Subsequently, when the standby control 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 = VCC/R2 4) DC offset protection block The DC offset protection circuit is activated 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 82kΩ resistor. Furthermore, the time constant must be determined using 22μ//22μ capacitors to prevent the amplifier from malfunctioning due to the audio signal.
