FUNCTIONAL DESCRIPTION
The TDA8563Q contains two identical amplifiers and can be used for bridge applications. The gain of each amplifier is fixed at 26 dB. Special features of the device are as follows.
Mode select switch (pin 11)
·Standby: low supply current
·Mute: input signal suppressed
·Operating: normal on condition.
Since this pin has a very low input current (<40 mA), 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 ³100 ms (charging of the input capacitors at pin 1 and pin 13).
This can be achieved by:
·Microprocessor control
·External timing circuit (see Fig.7).
Diagnostic output (pin 12)
DYNAMIC DISTORTION DETECTOR (DDD)
At the onset of clipping of one or more output stages, the dynamic distortion detector becomes active and pin 12 goes LOW. This information can be used to drive a sound processor or DC volume control to attenuate the input signal and thus limit the distortion. The output level of pin 12 is independent of the number of channels that are clipping (see Fig.3).

SHORT-CIRCUIT PROTECTION
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 20 ms, after removal of the short-circuit. During this short-circuit condition, pin 12 is continuously LOW.
When a short-circuit across the load of one or both channels occurs the output stages are switched off during approximately 20 ms. After that time it is checked during approximately 50 μs to see whether the short-circuit is still present. Due to this duty cycle of 50 μs/20 ms the average current consumption during this short-circuit condition is very low (approximately 40 mA).
During this short-circuit condition, pin 12 is LOW for 20 ms and HIGH for 50 μs (see Fig.4).
The power dissipation in any short-circuit condition is very low.
TEMPERATURE DETECTION
When the virtual junction temperature Tvj reaches 150 °C, pin 12 will become continuously LOW.
OPEN COLLECTOR OUTPUT
Pin 12 is an open collector output, which allows pin 12 of more devices being tied together.
