TDA8587J
4 × 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.

TDA8587J
Philips Semiconductors
4 × 25 W BTL power amplifier and regulator
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.

[1] Switched regulator (REG1) will be in regulation at VP ≥ 9.5 V.
[2] With increasing supply voltage at the overvoltage threshold, pin WARN goes HIGH-to-LOW.
[3] All modules are switched off, except the standby regulator (REG2), reset (delay) and warning function.
[4] All modules are enabled.
[5] Amplifiers are DC adjusted, but the input signal is suppressed.
[6] Amplifiers are capable of delivering maximum output power.
[7] Amplifiers are capable of delivering (internally) limited output power.
[8] 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 µA = 66.0 kΩ.
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 µA = 29.3 kΩ.
[9] This parameter is only measured in Production Validation (PV) tests.
[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.

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.
