FUNCTIONAL DESCRIPTION The TDA8564Q contains four identical amplifiers which can be used for single-ended or bridge applications. The gain of each amplifier is fixed at 40 dB (46 dB in BTL). Special features of the device are as follows. Mode select switch (pin 14) * Low standby current (<100 A) * Low switching current (low cost supply switch) * Mute facility. To avoid switch-on plops, it is advised to keep the amplifier in the mute mode during 100 ms (charging of the input capacitors at pins 1, 3, 15 and 17). This can be achieved by: * Microcontroller control * External timing circuit (see Fig.3). The circuit in Fig.3 slowly ramps up the voltage at the mode select switch pin when switching on and results in fast muting when switching off. In the event of fast switching at mode select pin it is advised to increase the 12VP decoupling capacitor (pin 4) to 150 F to avoid switch plops.

Diagnostic output (pin 16) DYNAMIC DISTORTION DETECTOR (DDD) At the onset of clipping of one or more output stages, the dynamic distortion detector becomes active and pin 16 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 16 is independent of the number of channels that are clipping (see Figs 4 and 5). 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 16 is continuously LOW. When a short-circuit across the load of one or more channels occurs the output stages are switched off during
TDA8564Q
approximately 20 ms. After that time it is checked during approximately 50 s to see whether the short-circuit is still present. Due to this duty cycle of 50 s/20 ms the average current consumption during this short-circuit condition is very low (approximately 40 mA). During this short-circuit condition, pin 16 is LOW for 20 ms and HIGH for 50 s (see Fig.6). The power dissipation in any short-circuit condition is very low. TEMPERATURE DETECTION When the virtual junction temperature Tvj reaches 150 C, pin 16 will be active LOW. OPEN-COLLECTOR OUTPUT Pin 16 is an open-collector output, which allows pin 16 of more devices being tied together.
