I2C-bus controlled 4 × 50 Watt power amplifier and multiple voltage regulator

FUNCTIONAL DESCRIPTION

The TDA8588 is a multiple voltage regulator combined withfour independent audiopoweramplifiers configured in bridge tied load with diagnostic capability. The output voltages of all regulators except regulators 2 and 3 can be controlledvia the I2C-bus.However, regulator 3 canbeset to 0 V via the I2C-bus. The output voltage of regulator 2 (microcontroller supply) and the maximum output voltage of regulator 3 (mechanical digital and microcontroller supplies) can bothbe either5 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 I2C-bus.
The amplifier diagnostic functions give information about output offset, load, or short-circuit. Diagnostic functions are controlled via the I2C-bus. The TDA8588 is protected against short-circuit, over-temperature, open ground and open VP 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 I2C-bus to prevent any noise generated by the fault condition from being heard.
TDA8588J; TDA8588xJ
Power-on reset and supply voltage spikes (see Fig.13 and Fig.14)
If the supply voltage drops too low to guarantee the integrity of the data in the I2C-bus latches, the power-on reset cycle will start. All latches will be setto 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 DIAGisan open-drain output, isactiveLOW, and must beconnected to anexternal 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 I2C-bus.
AMPLIFIERS Muting

Start-up

At power on, regulator 2 will reach its final voltage when thebackupcapacitor voltage exceeds 5.5 V independently of the voltageon pin STB. When pin STB isLOW, the total quiescent current is low, and the I2C-bus lines are high impedance.
When pin STB is HIGH, the I2C-bus is biased on and then the TDA8588 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
DIAG is no longer held LOW.
pin
Start-up and shut-down timing (see Fig.12) Acapacitorconnectedto 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 currentstandbymode is activated 2 secondsafterpin STB goes LOW.
Ahard mute anda soft mute canboth be performedviathe I2C-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 I2C-bus, a thermal protectionpre-warningisactivatedmakingpin DIAGLOW. If the temperature continues to rise, all four channels will be muted to reduce the output power (soft thermal clipping). The valueat whichthe 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 thetemperature mute controldoes not reducethe average junction temperature, allthe power stageswill beswitched off (muted) at the absolute maximum temperature T

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

compared with areference 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 whenthereis a mismatch betweenthepowercurrent 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
2
I
C-bus: short to ground (one side of the speaker connected to ground), short to VP(one side of the speaker connected to VP), and shorted load.

Line driver mode

TDA8588J; TDA8588xJ
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-coupledspeaker. The 19 kHz sine wave is alsoaudible during the test. Ifthe 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 switchedon and off. Thepeakcurrent counter can bereset 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 .
An amplifier can be used as a line driver by switching it to low gain mode. In normal mode, the gain between single-endedinput and differentialoutput (across theload) 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 ofthe 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,aDC-offset is appliedslowlytothe amplifier outputs, andthe output currentsare measured. If theoutput 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-upcycle, detection isinaudibleand can beperformed every time the amplifier is switched on.

LOAD DETECTION PROCEDURE
1. At start-up, enable the AC- or DC-load detection by setting D1 of instruction byte 1 to logic 1.
Page 10
Philips Semiconductors Product specification
I2C-bus controlled 4 × 50 Watt power amplifier and multiple voltage regulator
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 D5of each databyte should be readand stored by the microcontroller.
4. After at least 3 periods of the input signal, the load statuscan be checkedby reading AC-detectbits D4 of each data byte.
The AC-load peak current counter can be reset by settingbit D1 of instructionbyte IB1to 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 ofthe amplifieris 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.
TDA8588J; TDA8588xJ
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 VP voltage drop and the level of VP after the voltage drop (see Fig.4).
Ata certain supplyvoltage drop, the headroom voltagewill 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.4). 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 µA typical with only regulator 2 active. The TDA8588 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 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.

Backup capacitor

The backup capacitor is used as a backup supply for the regulator 2 output when the battery supply voltage (VP) 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 VP. It requires an external capacitor to be connected to pin BUCAP and ground. When the supply voltage is present on pin VP this capacitorwill be charged toalevel of VP− 0.3 V.When the supply voltage is absent from pin VP, this charge can then be used to supply regulator 2 for a brief period (t calculated using the formula:

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 notI2C-buscontrollableto prevent the microcontroller from being damaged byovervoltage which couldoccur during a disturbance of the I2C-bus. This supply will not shut down during load dump transients or during a high thermal-protection condition.

Reset delay capacitor

A Reset Delay Capacitor (RDC) connected to pin RESCAPcan be usedto extend thedelay 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 twopower switchesthat 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 switcheshave alow 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 istoo high is indicated bypin 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.

Supply decoupling

(see Fig.26) The high frequency 220 nF decoupling capacitors connected to power supply voltage pins 6 and 20 should be located
as close as possible to these pins. It is important to use good quality capacitors. These capacitors should be able to suppress high voltage peaks that can
occur on the power supply if several audio channels are accidentally shorted to the powersupply simultaneously, due to the activation of current protection. Good results have been achieved using 0805 case-size capacitors (X7R material, 220 nF) located close to power supply voltage pins 6 and 20.

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.32. 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.

EXAMPLE REGULATOR 2 Regulator 2 is stabilized with an electrolytic output capacitor of 10 µF which has an ESR of 4 . At T
capacitor value decreases to 3 µF and its ESR increases to 28 which is above the maximum allowed as shown in Fig.32, and which will make the regulator unstable. To avoid problems with stability at low temperatures, the recommendedsolution is touse tantalum capacitors.Eitheruse a tantalumcapacitor of 10 µF, oran electrolytic capacitor with a higher value.

SOLDERING Introduction to soldering through-hole mount
packages
This text gives a brief insight to wave, dip and manual soldering.A more in-depth accountof soldering ICs canbe found in our
Packages”
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.

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

“Data Handbook IC26; Integrated Circuit
(document order number 9398 652 90011).
Thetotalcontact time ofsuccessivesolderwaves 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 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.
