1998 Sep 23 5 Philips Semiconductors Product specification 4 × 25 W BTL quad car radio power amplifier TDA8567Q FUNCTIONAL DESCRIPTION The TDA8567Q contains four identical amplifiers which can be used for bridge applications. The gain of each amplifier is fixed at 26 dB. Mode select switch (pin 15) • Standby: low supply current (<100 µ A) • Mute: input signal suppressed • Operating: normal on condition. Since this pin has a low input current (<80 µA), a low cost supply switch can be applied. To avoid switch-on plops, it is advised to keep the amplifier in the mute mode during ≥150 ms (charging of the input capacitors at pins 10, 11, 13 and 14). When switching from standby to mute, the slope should be at least 18 V/s. This can be realized by: • Microprocessor control • External timing circuit (see Fig.3). Diagnostic output (pin 9) D YNAMIC DISTOR TION DETECTOR (DDD) At the onset of clipping of one or more output stages, the dynamic distortion detector becomes active and pin 9 goes LOW. This information can be used to drive a sound processor or DC volume control to attenuate the input signal and so limit the distortion. The output level of pin 9 is independent of the number of channels that are clipping (see Fig.4). S HORT - CIRCUIT DIAGNOSTIC When a short-circuit occurs at one or more outputs to ground or to the supply voltage, the output stages are switched off until the short-circuit is removed and the device is switched on again, with a delay of approximately 10 ms after removal of the short-circuit. During this short-circuit condition, pin 9 is continuously LOW. When a short-circuit occurs across the load of one or more channels, the output stages are switched off during approximately 10 ms. After that time it is checked during approximately 50 µs to determine whether the short-circuit is still present. Due to this duty cycle of 50 µs/10 ms the average current consumption during this short-circuit condition is very low. During this short-circuit condition, pin 9 is LOW for 10 ms and HIGH for 50 µs (see Fig.5). The protection circuits of all channels are coupled. This means that if a short-circuit condition occurs in one of the channels, all channels are switched off. Consequently, the power dissipation in any short-circuit condition is very low. T EMPERA TURE PRE -WARNING When the virtual junction temperature T vj reaches 145 °C, pin 9 goes LOW. O PEN COLLECTOR OUTPUTS The diagnostic pin has an open collector output, so more devices can be tied together. An external pull-up resistor is needed.

1998 Sep 23 16 Philips Semiconductors Product specification 4 × 25 W BTL quad car radio power amplifier TDA8567Q 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. This text gives a very brief insight to a complex technology. A more in-depth account of soldering ICs can be found in our “Data Handbook IC26; Integrated Circuit Packages” (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. The device may be mounted up to the seating plane, but the temperature of the plastic body must not exceed the specified maximum storage temperature (T stg max ). 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. 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.
