TDA8587J
4 x 25 W BTL power amplifier and multiple voltage regulator with power switch
Rev. 01 -- 23 December 2004 Preliminary data sheet
1. General description
The TDA8587J is a combination of a quad Bridge-Tied Load (BTL) power amplifier, a multiple voltage regulator and a power switch. Several protections and diagnostic options (e.g. DIAG, WARN) are incorporated in this design. This device is primarily developed to cover the complete power supply and audio amplifier requirements in low and mid-end car radio applications. The switchable regulators (regulators 1, 3 and 4) are intended to be used as supplies for the tuner, logic, digital or analog sound processor and CD / tape control. The standby regulator (regulator 2) is specially designed as supply for a microcontroller. In combination with the reset delay capacitor (pin RDC) and the reset output (pin RST), a proper start-up sequence for the microcontroller is guaranteed. The storage capacitor (pin STC) makes this regulator output insensitive for short battery drops (e.g. engine start). The power switch (pin PSW) can be used for switching e.g. an electrically powered antenna, display unit or CD / tape driver. The smart combination of two dynamic buffers and four amplifier output stages makes it possible to create a full quad BTL amplifier, using only six output pins.

7. Functional description
7.1 Mode select input
The mode select input pin (MODE) controls the operating mode of almost the entire device. The following functions are incorporated:
* Standby: all amplifier, regulator and power switch functions (except the standby
regulator, storage and reset function) are completely switched off
* Operating: all functions are enabled * Mute: the audio input signal is suppressed, so the amplifier outputs are only
DC-adjusted
* On: complete AC functionality of the amplifier outputs.
When in the on condition (VMODE VREG1) the amplifier outputs are capable of delivering full power to the loads (high-power mode). When VMODE > VREG1 the output power is internally limited (low-power mode). The RC combination at pin MODE is obligatory for a correctly operating temperature foldback and a plop-free switch-on and switch-off behavior.
7.2 Switchable regulators (regulator 1, regulator 3 and regulator 4)
Each of these mode pin controlled regulators (REG1 = 8.5 V, REG3 = 5 V and REG4 = 3.3 V) has an overload and short-circuit (foldback) protection. The regulators will be switched off during load dump or overtemperature conditions.
7.3 Standby regulator (regulator 2)
This 5 V standby regulator also has an individual overload and short-circuit (foldback) protection, but will not be switched off during load dump or overtemperature conditions. Special design precautions have been taken in this regulator to guarantee a low quiescent current in Standby mode. It is not controlled by the mode pin but it is switched on when the voltage of the storage capacitor (STC) exceeds a certain threshold level and switches off when its own output voltage falls below a given level which is far below the minimum engine start level. All regulator outputs have to be loaded with a ceramic and an electrolytic capacitor to guarantee stability and optimum noise performance over the complete ambient temperature range.
7.4 Storage capacitor
The storage capacitor is used as a back-up supply for the standby regulator, when the car battery cannot support the supply for this regulator anymore, e.g. in case of cold weather energization of the starter motor.

7.5 Reset output
The reset output pin (RST) is a push-pull output which is able to source and sink current. The output voltage can switch between the ground level and VREG2. This function is also supplied from the storage capacitor in case of low battery. The reset function is controlled by a low voltage detection circuit which pulls pin RST LOW when VREG2 is less than the reset threshold level. When VREG2 is greater than the reset threshold level the output goes HIGH. The timing of this function can be influenced by a reset delay capacitor, e.g. to avoid oscillations when VREG2 passes the internal threshold level.
7.6 Reset delay capacitor
The reset delay capacitor is used to delay the reset pulse, starting from the time when the rising VREG2 voltage crosses the reset threshold level; this will ensure a clean reset signal to the microcontroller. An internal current source is used to charge the reset delay capacitor and the reset output will be released (go HIGH) when the VRDC crosses the RDC threshold level. The reset delay capacitor also provides a time constant for the current protection of the power switch (PSW).
7.7 Power switch
The power switch is a non-regulated high current output voltage, which is almost equal to the supply voltage but is clamped in overvoltage conditions to avoid damage to the connected circuitry. It will be switched off during load dump and in overtemperature conditions. The power switch has three output current modes depending on its output voltage, the reset delay capacitor voltage and the junction temperature, i.e. high current, low current and foldback mode. The power switch can be loaded with light bulbs, relays or electrical motors and therefore, momentarily, excessive currents can flow at the start-up transition. It can operate in the high current mode for a selected time fixed by the reset delay capacitor. After this time-out the PSW output voltage has to be close to the battery voltage otherwise an overload or a short-circuit condition will be present and the power switch will be switched to the low current mode or to the foldback mode. The power switch can also operate in the low current mode when the standby regulator is overloaded or during excessive junction temperatures, but still below the overtemperature condition.

7.8 Warning output
The output of the warning pin (WARN) is an open-collector and therefore must have an external pull-up resistor (e.g. to the standby regulator). This output is active LOW. The warning output will be activated during the following conditions:
* When the output voltage of one (or more) switched regulator is out of regulation (due
to overload during normal operation, supply voltage drops or charging the output capacitors during start-up)
* When the power switch operates in the foldback mode (due to short-circuit during
normal operation and the time-out has finished)
* When during operation the overtemperature protection is activated (Tj 150 C) * When during any mode condition (i.e. standby, mute and on) the load dump protection
is activated
* When the circuit is in Standby mode and the battery voltage is very low, to indicate
that it is not possible to get all switched regulators into regulation if the circuit is switched on.
7.9 Audio inputs and reference voltage
The audio reference voltage acts with the four signal inputs to provide quasi-differential inputs. The ground side of the capacitor, connected to the audio reference voltage, should be tied to the ground at the signal source, usually the ground at an audio processor. It should be noted that for design reasons the inputs IN2A and IN2B have the opposite phase compared to inputs IN1A and IN1B. Care should be taken to ensure correct speaker polarity connection.
7.10 Amplifier and buffer outputs
Although there are only six output pins available, this device incorporates four BTL power amplifiers with a unique internal configuration. The system performs in an optimum manner (maximum BTL output power) when two related channels (IN1A and IN1B or IN2A and IN2B) have the same phase. In general, this will be the case for front and rear signals. Therefore it is recommended to use channels IN1A and IN1B for e.g. front and rear right and channels IN2A and IN2B for e.g. front and rear left. All amplifier and buffer outputs are protected against short-circuit to ground, and across the speakers. The amplifier outputs are also protected against short-circuit to the supply lines.

7.11 Diagnostic output
The output of the diagnostic pin (DIAG) is open-collector and therefore must have an external pull-up resistor (e.g. to regulator 3). This pin is active HIGH. The diagnostic output will be activated during the following conditions:
* Clip detection: when the amplifier is AC operating (low or high power), the diagnostic
output will indicate when clipping occurs at one or more outputs; this information can be used to drive a sound processor to attenuate the input signal and so limit the level of distortion
* Short-circuit diagnosis: the diagnostic output will indicate when one or more amplifier
outputs have a short-circuit to ground, supply lines or across the speaker
* Thermal foldback pre-warning: before the thermal foldback starts to affect the
amplifier output signal, the diagnostic pin will give a pre-warning.

This implies that a large current will flow when the battery is reverse connected, therefore external measures are needed to protect against this fault condition (reverse power diode and fuse).

Switched regulator (REG1) will be in regulation at VP 9.5 V. With increasing supply voltage at the overvoltage threshold, pin WARN goes HIGH-to-LOW. All modules are switched off, except the standby regulator (REG2), reset (delay) and warning function. All modules are enabled. Amplifiers are DC adjusted, but the input signal is suppressed. Amplifiers are capable of delivering maximum output power. Amplifiers are capable of delivering (internally) limited output power. The voltage drop across the external mode pin resistor (R1) at full foldback current should be sufficient to put the amplifiers in mute [VMODE VMODE(mute)(max)]. Example 1: mode pin supplied from VP = 14.4 V (low output power): R1 [VP - VMODE(mute)(max)]/IMODE(fb)(min) = (14.4 V - 4.5 V)/150 A = 66.0 k. Example 2: mode pin supplied from VREG1 (high output power): R1 [VREG1(max) - VMODE(mute)(max)]/IMODE(fb)(min) = (8.9 V - 4.5 V)/150 A = 29.3 k. This parameter is only measured in Production Validation (PV) tests.
[9]
[10] Diagnostic output activated, pin DIAG goes LOW-to-HIGH [11] Amplifier output signals will be gradually reduced to full mute at increasing junction temperature. [12] All switchable regulators and power switch will be switched off, pin WARN goes HIGH-to-LOW.

This parameter is only measured in product validation (PV) tests. Supply voltage enable function controls regulators 1, 3 and 4 and the power switch. Supply voltage is decreasing, pin WARN goes HIGH-to-LOW, indicates that VP is too low for proper regulation. Supply voltage is increasing, pin WARN goes LOW-to-HIGH, indicates that VP is sufficient for proper regulation. Reset delay capacitor voltage is increasing (see Regulator 2), at the threshold pin RST goes LOW-to-HIGH. Reset delay capacitor voltage is decreasing (see Regulator 2), at the threshold pin RST goes HIGH-to-LOW.

Drop-out voltage is measured with respect to VP. Pulse duration depends on value of the capacitor on pin RDC. For a typical shape of the foldback current protection; see Figure 6 and Figure 7.
[10] Power switch is loaded with a 1 kHz sine wave load current varying between 1 mA Io 1.4 A. [11] Crosstalk noise is selectively measured at the outputs of the other regulators and across the amplifier loads. [12] With decreasing power switch output, pin WARN goes HIGH-to-LOW. [13] Output current is not intended to be used for external circuitry (except for charging the storage capacitor). [14] Standby regulator is enabled when the increasing storage capacitor voltage reaches this threshold at first power-up. [15] Supply voltage ripple rejection is measured at output of the regulator; Vripple = 0.7 V. [16] Noise output voltage depends on the value of the regulator output capacitor. [17] Regulator 1 is loaded with a 1 kHz sine wave load current varying between: 1 mA Io 200 mA. [18] Regulator output is decreasing and goes out of regulation, pin WARN goes HIGH-to-LOW. [19] Regulator output is increasing and starts to regulate, pin WARN goes LOW-to-HIGH. [20] Dropout voltage is measured with respect to VSTC; VP pins connected to ground. [21] Regulator 2 is loaded with a 1 kHz sine wave load current varying between: 1 mA Io 200 mA. [22] Regulator output voltage is increasing, at the threshold the reset delay capacitor will be charged. [23] Regulator output voltage is decreasing, at the threshold the reset delay capacitor will be discharged. [24] Standby regulator is disabled when the decreasing output voltage reaches this threshold. [25] Regulator 3 is loaded with a 1 kHz sine wave load current varying between 1 mA Io 900 mA. [26] Regulator 4 is loaded with a 1 kHz sine wave load current varying between 1 mA Io 200 mA.

13. Soldering
13.1 Introduction to soldering through-hole mount packages
This text gives a brief insight to wave, dip and manual soldering. A more in-depth account of soldering ICs can be found in our Data Handbook IC26; Integrated Circuit Packages (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.
13.2 Soldering by dipping or by solder wave
Driven by legislation and environmental forces the worldwide use of lead-free solder pastes is increasing. Typical dwell time of the leads in the wave ranges from 3 seconds to 4 seconds at 250 C or 265 C, depending on solder material applied, SnPb or Pb-free respectively. 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 (Tstg(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.
13.3 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 C it may remain in contact for up to 10 seconds. If the bit temperature is between 300 C and 400 C, contact may be up to 5 seconds.
13.4 Package related soldering information
Table 10: Package CPGA, HCPGA DBS, DIP, HDIP, RDBS, SDIP, SIL PMFP [2]
[1] [2]
Suitability of through-hole mount IC packages for dipping and wave soldering methods Soldering method Dipping - suitable - Wave suitable suitable [1] not suitable
For SDIP packages, the longitudinal axis must be parallel to the transport direction of the printed-circuit board. For PMFP packages hot bar soldering or manual soldering is suitable.
