TDA1563Q
FUNCTIONAL DESCRIPTION
The TDA1563Q contains two identical amplifiers with differential inputs. At low output power (up to output amplitudes of 3 V (RMS) at VP= 14.4 V), the device operates as a normal SE amplifier. When a larger output voltage swing is needed, the circuit switches to BTL operation.
With a sine wave input signal, the dissipation of a conventionalBTL amplifier up to 2 W output power is more than twice the dissipation of the TDA1563Q (see Fig.10).
In normal use, when the amplifier is driven with music-like signals, the high (BTL) output power is only needed for a smallpercentageofthetime.Assumingthatamusicsignal has a normal (Gaussian) amplitude distribution, the dissipation of a conventional BTL amplifier with the same output power is approximately 70% higher (see Fig.11).
The heatsink has to be designed for use with music signals. With such a heatsink, the thermal protection will disable the BTL mode when the junction temperature exceeds 150 °C.In this case, the output poweris limited to 5 W per amplifier.
The gain of each amplifier is internally fixed at 26 dB. With the MODE pin, the device can be switched to the following modes:
Standby with low standby current (<50 µA)
Mute condition, DC adjusted
On, operation.
The information on pin 12 (selectable clip) determines at which distortion figures a clip detection signal will be generated at the clip output. A logic 0 applied to pin 12 will select clip detection at THD = 10%, a logic 1 selects THD = 2.5%. A logic 0 can be realised by connecting this pin to ground. A logic 1 can be realised by connecting it to V
logic
(see Fig.7) or the pin can also be left open. Pin 12 may not be connected to VP because its maximum input voltage is 18 V (VP> 18 V under load dump conditions).
The device is fully protected against a short circuit of the output pins to ground and to the supply voltage. It is also protected against a short circuit of the loudspeaker and against high junction temperatures. In the event of a permanentshortcircuittogroundorthesupplyvoltage, the output stage will be switched off, causing low dissipation. With a permanent short circuit of the loudspeaker, the output stage will be repeatedly switched on and off. In the ‘on’ condition, the duty cycle is low enough to prevent excessive dissipation.
To avoid plops during switching from ‘mute’ to ‘on’ or from ‘on’ to ‘mute/standby’ while an input signal is present, a built-in zero-crossing detector only allows switching at zero input voltage. However, when the supply voltage drops below 6 V (e.g. engine start), the circuit mutes immediately, avoiding clicks from the electronic circuit preceding the power amplifier.
The voltage of the SE electrolytic capacitor (pin 4) is kept at 0.5VP by a voltage buffer (see Fig.1). The value of this capacitor has an important influence on the output power in SE mode. Especially at low signal frequencies, a high value is recommended to minimize dissipation.
The two diagnostic outputs (clip and diag) are open-collector outputs and require a pull-up resistor.
The clip output will be LOW when the THD of the output signal is higher than the selected clip level (10% or 2.5%).
The diagnostic output gives information:
about short circuit protection: – When a short circuit (to ground or the supply voltage)
occurs at the outputs (for at least 10 µs), the output stages are switched off to prevent excessive dissipation. The outputs are switched on again approximately 50 ms after the short circuit is removed. During this short circuit condition, the protection pin is LOW.
– When a short circuit occurs across the load (for at
least 10 µs), the output stages are switched off for approximately50 ms.Afterthistime,acheckis made to see whether the short circuit is still present. The power dissipation in any short circuit condition is very low.
during startup/shutdown, when the device is internally muted.
temperaturedetection: This signal (junctiontemperature > 145°C) indicates that the temperature protection will becomeactive. The temperature detection signal can be used to reduce the input signal and thus reduce the power dissipation.

Heatsink design
There are two parameters that determine the size of the heatsink. The first is the rating for the virtual junction temperature and the second is the ambient temperature at which the amplifier must still deliver its full power in the BTL mode.
With a conventional BTL amplifier, the maximum power dissipation with a music-like signal (at each amplifier) will be approximately two times 6.5 W.
