TDA8571J

FUNCTIONAL DESCRIPTION

SHORT-CIRCUIT DIAGNOSTIC

The TDA8571J contains four identical amplifiers which can

be used for bridge applications. The gain of each amplifier

is fixed at 34 dB.

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_DIAGis continuously LOW.

Mode select switch (pin MODE)

• Standby: low supply current (<100 µA)

• Mute: input signal suppressed

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 µs to determine whether the short-circuit

is still present. Due to this duty cycle of 50 µs/10 ms the

average current consumption during this short-circuit

condition is very low.

• Operating: normal on condition.

Since this pin has a low input current (<80 µA), 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 ≥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:

During this short-circuit condition, pin V_DIAGis LOW for

10 ms and HIGH for 50 µs (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.

• Microprocessor control

• External timing circuit (see Fig.3).

Diagnostic output (pin V_DIAG

)

TEMPERATURE PRE-WARNING

DYNAMIC DISTORTION DETECTOR (DDD)

When the virtual junction temperature T_vjreaches 145 °C,

pin V_DIAGgoes LOW.

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_DIAGis independent of the number of channels that

are clipping (see Fig.4).

OPEN-COLLECTOR OUTPUTS

The diagnostic pin has an open-collector output, so more

devices can be tied together. An external pull-up resistor is

needed.

Special care must be taken in the PCB-layout to separate pin V_DIAGfrom the pins IN1, IN2, IN3 and IN4 to minimize the crosstalk between the clip output

and the inputs.

To avoid switch-on plops, it is advised to keep the amplifier in the mute mode during a period of ≥ 150 ms (charging the input capacitors at pins IN1,

IN2, IN3 and IN4).

SOLDERING

The total contact time of successive solder waves must not

exceed 5 seconds.

Introduction to soldering through-hole mount

packages

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.

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.

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

Soldering by dipping or by solder wave

The maximum permissible temperature of the solder is

260 °C; solder at this temperature must not be in contact

with the joints for more than 5 seconds.

300 and 400 °C, contact may be up to 5 seconds.
