2002 Mar 05 5 Philips Semiconductors Product speciï¬Âcation 4 à40 W BTL quad car radio po wer ampliï¬Âer TD A8571J FUNCTIONAL DESCRIPTION The TDA8571J contains four identical amplifiers which can be used for bridge applications. The gain of each amplifier is fixed at 34 dB. Mode select switch (pin MODE) ⢠Standby: low supply current (<100 õ A) ⢠Mute: input signal suppressed ⢠Operating: normal on condition. Since this pin has a low input current (<80 õA), 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 âÂÂ¥150 ms (charging of the input capacitors at pins IN1, IN2, IN3 and IN4. 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 V DIA G ) D YNAMIC DIST ORTION DETECT OR (DDD) At the onset of clipping of one or more output stages, the dynamic distortion detector becomes active and pin V DIAG 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 V DIAG 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 V DIAG 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 õs to determine whether the short-circuit is still present. Due to this duty cycle of 50 õs/10 ms the average current consumption during this short-circuit condition is very low. During this short-circuit condition, pin V DIAG is LOW for 10 ms and HIGH for 50 õs (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 ðC, pin V DIAG goes LOW. O PEN- COLLECT OR OUTPUTS The diagnostic pin has an open-collector output, so more devices can be tied together. An external pull-up resistor is needed.

A more in-depth account of soldering ICs can be found in our âÂÂData Handbook IC26; Integrated Circuit Packagesâ (document order number 9398 652 90011). Wave soldering is the preferred method for mounting of through-hole mount IC packages on a printed-circuit board. Soldering by dipping or b y solder wave The maximum permissible temperature of the solder is 260 ðC; solder at this temperature must not be in contact with the joints 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. Manual soldering Apply the soldering iron (24 V or less) to the lead(s) of the package, either below the seating plane or not more than 2 mm above it. If the temperature of the soldering iron bit is less than 300 ðC it may remain in contact for up to 10 seconds. If the bit temperature is between 300 and 400 ðC, contact may be up to 5 seconds. Suitability of through-hole mount IC pac kages for dipping and wave soldering methods Note 1. For SDIP packages, the longitudinal axis must be parallel to the transport direction of the printed-circuit board.

2002 Mar 05 5 Philips Semiconductors Product speciï¬Âcation 4 à40 W BTL quad car radio po wer ampliï¬Âer TD A8571J FUNCTIONAL DESCRIPTION The TDA8571J contains four identical amplifiers which can be used for bridge applications. The gain of each amplifier is fixed at 34 dB. Mode select switch (pin MODE) ⢠Standby: low supply current (<100 õ A) ⢠Mute: input signal suppressed ⢠Operating: normal on condition. Since this pin has a low input current (<80 õA), 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 âÂÂ¥150 ms (charging of the input capacitors at pins IN1, IN2, IN3 and IN4. 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 V DIA G ) D YNAMIC DIST ORTION DETECT OR (DDD) At the onset of clipping of one or more output stages, the dynamic distortion detector becomes active and pin V DIAG 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 V DIAG 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 V DIAG 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 õs to determine whether the short-circuit is still present. Due to this duty cycle of 50 õs/10 ms the average current consumption during this short-circuit condition is very low. During this short-circuit condition, pin V DIAG is LOW for 10 ms and HIGH for 50 õs (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 ðC, pin V DIAG goes LOW. O PEN- COLLECT OR OUTPUTS The diagnostic pin has an open-collector output, so more devices can be tied together. An external pull-up resistor is needed.

A more in-depth account of soldering ICs can be found in our âÂÂData Handbook IC26; Integrated Circuit Packagesâ (document order number 9398 652 90011). Wave soldering is the preferred method for mounting of through-hole mount IC packages on a printed-circuit board. Soldering by dipping or b y solder wave The maximum permissible temperature of the solder is 260 ðC; solder at this temperature must not be in contact with the joints 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. Manual soldering Apply the soldering iron (24 V or less) to the lead(s) of the package, either below the seating plane or not more than 2 mm above it. If the temperature of the soldering iron bit is less than 300 ðC it may remain in contact for up to 10 seconds. If the bit temperature is between 300 and 400 ðC, contact may be up to 5 seconds. Suitability of through-hole mount IC pac kages for dipping and wave soldering methods Note 1. For SDIP packages, the longitudinal axis must be parallel to the transport direction of the printed-circuit board.
