GENERAL DESCRIPTION

Ampli

ers

The TDA8589 has a complementary quad audio power
amplifier that uses BCDMOS technology. It contains four
amplifiers configured in Bridge Tied Load (BTL) to drive
speakers for front and rear left and right channels. The
I

C-bus allows diagnostic information of each amplifier and

its speaker to be read separately. Both front and both rear
channel amplifiers can be configured independently in line
driver mode with a gain of 20 dB (differential output).

Voltage regulators

The TDA8589 has a multiple output voltage regulator with
two power switches.

The voltage regulator contains the following:

Four switchable regulators and one permanently active
regulator (microcontroller supply)
Two power switches with loss-of-ground protection
A reset output that can be used to communicate with a
microcontroller.

The quiescent current has a very low level of 150 A with
only regulator 2 active.

FUNCTIONAL DESCRIPTION

The TDA8589 is a multiple voltage regulator combined
with four independent audio power amplifiers configured in
bridge tied load with diagnostic capability. The output
voltages of all regulators except regulators 2 and 3 can be
controlled via the I

C-bus. However, regulator 3 can be set

to 0 V via the I

C-bus. The output voltage of regulator 2

(microcontroller supply) and the maximum output voltage
of regulator 3 (mechanical digital and microcontroller
supplies) can both be either 5 V or 3.3 V depending on the
type number. The maximum output voltages of both
regulators are fixed to avoid any risk of damaging the
microcontroller that may occur during a disturbance of the
I

C-bus.

The amplifier diagnostic functions give information about
output offset, load, or short-circuit. Diagnostic functions
are controlled via the I

C-bus. The TDA8589 is protected

against short-circuit, over-temperature, open ground and
open V

connections. If a short-circuit occurs at the input

or output of a single amplifier, that channel shuts down,
and the other channels continue to operate normally. The
channel that has a short-circuit can be disabled by the
microcontroller via the appropriate enable bit of the
I

C-bus to prevent any noise generated by the fault

condition from being heard.

Start-up

At power on, regulator 2 will reach its final voltage when
the backup capacitor voltage exceeds 5.5 V independently
of the voltage on pin STB. When pin STB is LOW, the total
quiescent current is low, and the I

C-bus lines are high

impedance.

When pin STB is HIGH, the I

C-bus is biased on and then

the TDA8589 performs a power-on reset. When bit D0 of
instruction byte IB1 is set, the amplifier is activated, bit D7
of data byte 2 (power-on reset occurred) is reset, and
pin DIAG is no longer held LOW.

Start-up and shut-down timing (see Fig.12)

A capacitor connected to pin SVR enables smooth start-up
and shut-down, preventing the amplifier from producing
audible clicks at switch-on or switch-off. The start-up and
shut-down times can be extended by increasing the
capacitor value.

If the amplifier is shut down using pin STB, the amplifier is
muted, the regulators and switches are switched off, and
the capacitor connected to pin SVR discharges. The low
current standby mode is activated 2 seconds after pin STB
goes LOW.

Power-on reset and supply voltage spikes (see Fig.13
and (see Fig.14))

If the supply voltage drops too low to guarantee the
integrity of the data in the I

C-bus latches, the power-on

reset cycle will start. All latches will be set to a pre-defined
state, pin DIAG will be pulled LOW to indicate that a
power-on reset has occurred, and bit D7 of data byte 2 is
also set for the same reason. When D0 of instruction
byte 1 is set, the power-on flag resets, pin DIAG is
released and the amplifier will then enter its start-up cycle.

Diagnostic output

Pin DIAG indicates clipping, thermal protection
pre-warning of amplifier and voltage regulator sections,
short-circuit protection, low and high battery voltage.
Pin DIAG is an open-drain output, is active LOW, and must
be connected to an external voltage via an external pull-up
resistor. If a failure occurs, pin DIAG remains LOW during
the failure and no clipping information is available. The
microcontroller can read the failure information via the
I

C-bus.

AMPLIFIERS

Muting

A hard mute and a soft mute can both be performed via the
I

C-bus. A hard mute mutes the amplifier within 0.5 ms.

A soft mute mutes the amplifier within 20 ms and is less
audible. A hard mute is also activated if a voltage of 8 V is
applied to pin STB.

Temperature protection

If the average junction temperature rises to a temperature
value that has been set via the I

C-bus, a thermal

protection pre-warning is activated making pin DIAG LOW.
If the temperature continues to rise, all four channels will
be muted to reduce the output power (soft thermal
clipping). The value at which the temperature mute control
activates is fixed; only the temperature at which the
thermal protection pre-warning signal occurs can be
specified by bit D4 in instruction byte 3. If implementing
the temperature mute control does not reduce the average
junction temperature, all the power stages will be switched
off (muted) at the absolute maximum temperature T

j(max)

Offset detection

Offset detection can only be performed when there is no
input signal to the amplifiers, for instance when the
external digital signal processor is muted after a start-up.

The output voltage of each channel is measured and

cation

ampli

er and multiple voltage regulator

TDA8589J; TDA8589xJ

compared with a reference voltage. If the output voltage of
a channel is greater than the reference voltage, bit D2 of
the associated data byte is set and read by the
microcontroller during a read instruction. Note that the
value of this bit is only meaningful when there is no input
signal and the amplifier is not muted. Offset detection is
always enabled.

Speaker protection

If one side of a speaker is connected to ground, a missing
current protection is implemented to prevent damage to
the speaker. A fault condition is detected in a channel
when there is a mismatch between the power current in the
high side and the power current in the low side; during a
fault condition the channel will be switched off.

The load status of each channel can be read via the
I

C-bus: short to ground (one side of the speaker

connected to ground), short to V

(one side of the speaker

connected to V

), and shorted load.

Line driver mode

An amplifier can be used as a line driver by switching it to
low gain mode. In normal mode, the gain between
single-ended input and differential output (across the load)
is 26 dB. In low gain mode the gain between single-ended
input and differential output is 20 dB.

Input and AC ground capacitor values

The negative inputs to all four amplifier channels are
combined at pin ACGND. To obtain the best performance
for supply voltage ripple rejection and unwanted audible
noise, the value of the capacitor connected to pin ACGND
must be as close as possible to 4 times the value of the
input capacitor connected to the positive input of each
channel.

Load detection

DC-

LOAD DETECTION

When DC-load detection is enabled, during the start-up
cycle, a DC-offset is applied slowly to the amplifier outputs,
and the output currents are measured. If the output current
of an amplifier rises above a certain level, it is assumed
that there is a load of less than 6 and bit D5 is reset in
the associated data byte register to indicate that a load is
detected.

Because the offset is measured during the amplifier
start-up cycle, detection is inaudible and can be performed
every time the amplifier is switched on.

AC-

LOAD DETECTION

AC-load detection can be used to detect that AC-coupled
speakers are connected correctly during assembly. This
requires at least 3 periods of a 19 kHz sine wave to be
applied to the amplifier inputs. The amplifier produces a
peak output voltage which also generates a peak output
current through the AC-coupled speaker. The 19 kHz sine
wave is also audible during the test. If the amplifier detects
three current peaks that are greater than 550 mA, the
AC-load detection bit D1 of instruction byte IB1 is set to
logic 1. Three current peaks are counted to avoid false
AC-load detection which can occur if the input signal is
switched on and off. The peak current counter can be reset
by setting bit D1 of instruction byte IB1 to logic 0.
To guarantee AC-load detection, an amplifier current of
more than 550 mA is required. AC-load detection will
never occur with a current of less than 150 mA. Figure 3
shows which AC loads are detected at different output
voltages. For example, if a load is detected at an output
voltage of 2.5 V peak, the load is less than 4 . If no load
is detected, the output impedance is more than 14 .

OAD DETECTION PROCEDURE

2. After 250 ms the DC load is detected and the mute is

released. This is inaudible and can be implemented
each time the IC is powered on.

3. When the amplifier start-up cycle is completed (after

1.5 s), apply an AC signal to the input, and DC-load
bits D5 of each data byte should be read and stored by
the microcontroller.

4. After at least 3 periods of the input signal, the load

status can be checked by reading AC-detect bits D4 of
each data byte.
The AC-load peak current counter can be reset by
setting bit D1 of instruction byte IB1 to logic 0 and then
to logic 1. Note that this will also reset the DC-load
detection bits D5 in each data byte.

Low headroom protection

The normal DC output voltage of the amplifier is set to half
the supply voltage and is related to the voltage on
pin SVR. An external capacitor is connected to pin SVR to
suppress power supply ripple. If the supply voltage drops
(at vehicle engine start), the DC output voltage will follow
slowly due to the affect of the SVR capacitor.

The headroom voltage is the voltage required for correct
operation of the amplifier and is defined as the voltage
difference between the level of the DC output voltage
before the V

voltage drop and the level of V

after the

voltage drop (see Fig.4).

At a certain supply voltage drop, the headroom voltage will
be insufficient for correct operation of the amplifier.
To prevent unwanted audible noises at the output, the
headroom protection mode will be activated (see Fig.13).
This protection discharges the capacitors connected to
pins SVR and ACGND to increase the headroom voltage.

VOLTAGE REGULATORS

The voltage regulator section contains:

Four switchable regulators and one permanent active
regulator
Two power switches with loss-of-ground protection
Reset push-pull output
Backup functionality.

The quiescent current condition has a very low current
level of 150 A typical with only regulator 2 active. The
TDA8589 uses low dropout voltage regulators for use in
low voltage applications.

All of the voltage regulators except for the standby
regulator can be controlled via the I

C-bus. The voltage

regulator section of this device has two power switches
which are capable of delivering unregulated 400 mA
continuous current, and has several fail-safe protection
modes. It conforms to peak transient tests and protects
against continuous high voltage (24 V), short-circuits and
thermal stress. A reset warning signal is asserted if
regulator 2 is out of regulation. Regulator 2 will try to
maintain output for as long as possible even if a thermal
shut-down or any other fault condition occurs. During
overvoltage stress conditions, all outputs except
regulator 2 will switch off and the device will be able to
supply a minimum current for an indefinite amount of time
sufficient for powering the memory of a microcontroller.
Provision is made for an external reserve supply capacitor
to be connected to pin BUCAP which can store enough
energy to allow regulator 2 to supply a microcontroller for
a period long enough for it to prepare for a loss-of-voltage.

Regulator 2

Regulator 2 is intended to supply the microcontroller and
has a low quiescent current. This supply cannot be shut
down in response to overvoltage stress conditions, and is
not I

C-bus controllable to prevent the microcontroller from

being damaged by overvoltage which could occur during a
disturbance of the I

C-bus. This supply will not shut down

during load dump transients or during a high
thermal-protection condition.

Backup capacitor

The backup capacitor is used as a backup supply for the
regulator 2 output when the battery supply voltage (V

)

cannot support the regulator 2 voltage.

Backup function

The backup function is implemented by a switch function,
which behaves like an ideal diode between pins V

and BUCAP; the forward voltage of this ideal diode
depends on the current flowing through it. The backup
function supplies regulator 2 during brief periods when no
supply voltage is present on pin V

. It requires an external

capacitor to be connected to pin BUCAP and ground.
When the supply voltage is present on pin V

this

capacitor will be charged to a level of V

0.3 V. When the

supply voltage is absent from pin V

, this charge can then

be used to supply regulator 2 for a brief period (t

backup

)

calculated using the formula:

Example: V

= 14.4 V, V

O(REG2)

= 5 V, R

= 1 k and

backup

= 100 F provides a t

backup

of 177 ms.

When an overvoltage condition occurs, the voltage on
pin BUCAP is limited to approximately 24 V; see Fig.5.

Reset output

A reset pulse is generated at pin RST when the output
voltage of regulator 2 rises above the reset threshold
value. The reset output is a push-pull output that both
sources and sinks current. The output voltage can switch
between ground and V

O(REG2)

, and operates at a low

regulator 2 voltage or V

BUCAP

. The RST signal is controlled

by a low-voltage detection circuit which, when activated,
pulls pin RST LOW (reset active) when V

O(REG2)

th(rst)

. If V

O(REG2)

th(rst)

, pin RST goes HIGH. The

reset pulse is delayed by 40 s internally. To extend the
delay and to prevent oscillations occurring at the threshold
voltage, an external capacitor can be connected to
pin RESCAP. Note that a reset pulse is not generated
when V

O(REG2)

falls below the reset threshold value.

Reset delay capacitor

A Reset Delay Capacitor (RDC) connected to
pin RESCAP can be used to extend the delay period of the
reset pulse and to ensure that a clean reset signal is sent
to the microcontroller. The RDC is charged by a current
source. The reset output (pin RST) will be released
(pin RST goes HIGH) when the RDC voltage crosses the
RDC threshold value.

Power switches

There are two power switches that provide an unregulated
DC voltage output for amplifiers and an aerial motor
respectively. The switches have internal protection for
over-temperature conditions and are activated by setting
bits D2 and D3 of instruction byte IB1 to logic 1. The
regulated outputs will supply pulsed current loads that can
contaminate the line with high frequency noise, so it is
important to prevent any cross-coupling between the
regulated outputs, particularly with the 8.3 V audio supply,
and the unregulated outputs.

In the ON state, the switches have a low impedance to the
battery voltage. When the battery voltage is higher than
22 V, the switches are switched off. When the battery
voltage is below 22 V the switches are set to their original
condition.

Protection

All regulator and switch outputs are fully protected by
foldback current limiting against load dumps and
short-circuits; see Fig.6. During a load dump all regulator
outputs, except the output of regulator 2, will go low.

The power switches can withstand

loss-of-ground

. This

means that if pin GND becomes disconnected, the switch
is protected by automatically connecting its outputs to
ground.

Temperature protection

If the junction temperature of a regulator becomes too
high, the amplifier(s) are switched off to prevent unwanted
noise signals being audible. A regulator junction
temperature that is too high is indicated by pin DIAG going
LOW and is also indicated by setting bit D6 in data byte 2.

If the junction temperature of the regulator continues to
rise and reaches the maximum temperature protection
level, all regulators and switches will be disabled except
regulator 2.

Notes
1. The quiescent current is measured in standby mode when R

= .

2. The rise and fall times are measured with a 50 pF load capacitor.
3. The reset delay time depends on the value of the reset delay capacitor:

4. The dropout voltage of a regulator is the voltage difference between V

and V

O(REGn)

5. At current limit, V

O(REGn)

is held constant (see Fig.6).

6. The foldback current protection limits the dissipation power at short-circuit (see Fig.6).

Beep input circuit

Beep input circuit to amplify the beep signal from the microcontroller to all 4 amplifiers (gain = 0 dB). Note that this circuit
will not affect amplifier performance.

Noise

The outputs of regulators 1 to 5 are designed to give very low noise with good stability. The noise output voltage depends
on output capacitor C

. Table 11 shows the affect of the output capacitor on the noise figure.

gures

Note
1. Measured in the frequency range 20 Hz to 80 kHz.

Stability

The regulators are made stable by connecting capacitors to the regulator outputs. The stability can be guaranteed with
almost any output capacitor if its Electric Series Resistance (ESR) stays below the ESR curve shown in Fig.34. If an
electrolytic capacitor is used, its behaviour with temperature can cause oscillations at extremely low temperature.
Oscillation problems can be avoided by adding a 47 nF capacitor in parallel with the electrolytic capacitor. The following
example describes how to select the value of output capacitor.

SOLDERING

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

(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 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 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 (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 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.

Suitability of through-hole mount IC packages for dipping and wave soldering methods

Notes
1. For SDIP packages, the longitudinal axis must be parallel to the transport direction of the printed-circuit board.
2. For PMFP packages hot bar soldering or manual soldering is suitable.
