TDA8569Q
FUNCTIONAL DESCRIPTION
SHORT-CIRCUIT DIAGNOSTIC
The TDA8569Q contains four identical amplifiers which
can be used for bridge applications. The gain of each
amplifier is fixed at 26 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 VDIAG is continuously LOW.
Mode select switch (pin MODE)
• Standby: low supply current (<100 µA)
When a short-circuit occurs across the load of one or more
channels, the output stages are switched off for
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.
• Mute: input signal suppressed
• 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).
During this short-circuit condition, pin VDIAG is 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.
This can be realized by:
• Microprocessor control
• External timing circuit (see Fig.3).
Diagnostic output (pin VDIAG)
TEMPERATURE PRE-WARNING
DYNAMIC DISTORTION DETECTOR (DDD)
When the virtual junction temperature Tvj reaches 145 °C,
pin VDIAG goes LOW.
At the onset of clipping of one or more output stages, the
dynamic distortion detector becomes active and pin VDIAG
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 VDIAG is 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 VDIAG from 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 for a period of ≥150 ms (charging the input capacitors at
pins IN1, IN2, IN3 and IN4).

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