By measuring this voltage, external actions can be taken to reduce an excessive temperature (e.g. by cutting off low frequencies or externally switching to class-B). For the relationship between the crystal temperature and the voltage on this pin, see Fig.3. FUNCTIONAL DESCRIPTION The TDA1560Q contains a mono class-H BTL output power amplifier. At low output power, up to 10 W, the device operates as a normal BTL amplifier. When a larger output voltage swing is required, the internal supply voltage is lifted to approximately twice the external supply voltage. This extra supply voltage is obtained from the charge in the external electrolytic capacitors. Due to this momentarily higher supply voltage, the maximum output power is 40 W typical at a THD of 10%. By forcing a high voltage level on the class-B/class-H pin, thereby simulating a high temperature, the device can be externally switched to class-B operation. Similarly, by forcing a low voltage level on the class-B/class-H pin, thereby simulating a low temperature, the device can be forced into class-H operation, even if the case temperature exceeds 120 °C. In normal use, when the output is driven with music-type signals, the high output power is only required for a small percentage of the time. Assuming a music signal has a normal (Gaussian) amplitude distribution, the reduction in dissipation is approximately 50% when compared to a class-B output amplifier with the same output power. The heatsink should be designed for use with music signals. The device is fully protected against short-circuiting of the outputs to ground or VP and across the load, high crystal temperature and electrostatic discharge at all input and output pins. In the event of a continuing short-circuit to ground or VP, excessive dissipation is prevented because the output stages will be switched off. The output stages will be switched on again within 20 ms after the short-circuit has been removed. If the device is continuous sine wave driven, instead of driven with music signals and at a high output power (class-H operation), the case temperature can rise above 120 °C with such a practical heatsink. In this event, the thermal protection disables the high power supply voltage and limits the output power to 10 W and the maximum dissipation to 5 W. A diagnostic facility is available at pin 14. In normal conditions the voltage at this pin will be the supply voltage (VP). In the event of the following conditions: • Junction temperature exceeds 150 °C The gain of each amplifier is internally fixed at 30 dB. With the mode select input the device can be switched to the following modes: • Short-circuit of one of the outputs to ground or to VP • Load dump; VP > 20 V. • Low standby current (<50 µA) The voltage level at pin 14 will be at a constant level of approximately 1⁄2VP during fault condition. At a short-circuit over the load, pin 14 will be at 1⁄2VP for approximately 20 ms and VP for approximately 50 µs. • Mute condition, DC adjusted • On, operation in class-B, limited output power • On, operation in class-H, high output power. The device can be used as a normal BTL class-AB amplifier if the electrolytic capacitors C1 and C2 are omitted; see Fig.6. If the case temperature exceeds 120 °C, the device will switch back from class-H to class-B operation. The high power supply voltage is then disabled and the output power is limited to 10 W. By measuring the voltage on the class-B/class-H pin, the actual crystal temperature can be detected. 1996 May 14 5 Philips Semiconductors Product specification 40 W car radio high power amplifier TDA1560Q LIMITING VALUES In accordance with the Absolute Maximum Rating System (IEC 134).

The first is the rating for the case temperature and the second is the ambient temperature at which the amplifier must still deliver its full power in the class-H mode. With disabled class-H mode, an 8 Ω load and driven with a sine wave signal the maximum power dissipation is approximately 5 W. At a virtual junction temperature of 150 °C and Tamb(max) at 60 °C, Rth vj-case = 3 K/W and Rth case-h = 1 K/W the thermal resistance of the heatsink should be: EXAMPLE 1 150 – 60 ---------------------- – 3 – 1 = 14 K/W 5 With an 8 Ω load and driven with a music signal, the maximum power dissipation is approximately 6.5 W. If the amplifier is to deliver its full power at ambient temperatures up to 50 °C the case temperature should not be higher than120 °C for class-H operation. In this example the size of the heatsink is determined by the virtual junction temperature. Rth case-h = 1 K/W, thus the external heatsink should be: 120 – 50 ---------------------- – 1.0 = 10 K/W 6.5 In this example and with an 8 Ω load, the size of the heatsink is determined by the rating for the maximum full power ambient temperature. If the case temperature of the device exceeds 120 °C then the device switches back to class-B, see “Example 2”. 1996 May 14 6 Philips Semiconductors Product specification 40 W car radio high power amplifier TDA1560Q DC CHARACTERISTICS VP = 14.4 V; RL = 8 Ω; Tamb = 25 °C and using 4 K/W heatsink; measured in Fig.6; unless otherwise specified.

The circuit is DC adjusted at VP = 8 to 18 V and AC operating at VP = 8.5 to 18 V. 2. The DC output voltage, or the common mode voltage on the loudspeaker terminals with respect to ground, is 6.3 V at output power up to 8.5 W. At higher output power, the common mode voltage will be higher. 3. The voltage at pin 14 is approximately 1⁄2VP in the event of a short-circuit, load dump or temperature protection. Any circuit connected to pin 14 should have an input resistance of >2 MΩ and an input capacitance of <5 nF. 4. The DC output offset voltage step is the difference in output offset voltage in the mute condition and the on condition. The absolute value of this voltage step is given as +∆Vo mute − ∆Vo on < 150 mV. 5. Figure 3 shows the relationship between the global crystal temperature and the open voltage at the class-B/class-H pin. 6. The maximum voltage on pin 17 is VP − 1 (VP ≤ 18 V). 1996 May 14 7 Philips Semiconductors Product specification 40 W car radio high power amplifier TDA1560Q VP MCD332 - 1 3 handbook, halfpage handbook, halfpage Class - H 8.5 8 V17 (V) 95% V16 50% (V) 7 2 6 5% Class - B 5 4 1 3 Mute 2 0 0 40 80 120 Tvj ( oC) 1 160 Standby 0 MCD331 - 1 Fig.3 Class-B/class-H pin voltage level. 1996 May 14 Fig.4 Switching levels of mode select switch. 8 Philips Semiconductors Product specification 40 W car radio high power amplifier TDA1560Q AC CHARACTERISTICS VP = 14.4 V; RL = 8 Ω; fi = 1 kHz; Tamb = 25 °C and using 4 K/W heatsink; measured in Fig.6; unless otherwise specified.

With a continuous sine wave input signal the output power is approximately 1 W less than driven with a bursted signal; also depending on the equivalent series resistance of the electrolytic capacitors C1 and C2 (see Fig.6) and the resistance of the connections between pins 5, 8, 10 and 13 and C1, C2. 2.

If the printed-circuit board has been pre-heated, forced cooling may be necessary immediately after soldering to keep the temperature within the permissible limit. SOLDERING Introduction There is no soldering method that is ideal for all IC packages. Wave soldering is often preferred when through-hole and surface mounted components are mixed on one printed-circuit board. However, wave soldering is not always suitable for surface mounted ICs, or for printed-circuits with high population densities. In these situations reflow soldering is often used. Repairing soldered joints Apply a low voltage soldering iron (less than 24 V) to the lead(s) of the package, below the seating plane or not more than 2 mm above it. If the temperature of the soldering iron bit is less than 300 °C it may remain in contact for up to 10 seconds. If the bit temperature is between 300 and 400 °C, contact may be up to 5 seconds. This text gives a very brief insight to a complex technology. A more in-depth account of soldering ICs can be found in our “IC Package Databook” (order code 9398 652 90011). Soldering by dipping or by wave The maximum permissible temperature of the solder is 260 °C; solder at this temperature must not be in contact with the joint for more than 5 seconds. The total contact time of successive solder waves must not exceed 5 seconds.
