MOSFET OUTPUT POWER STAGE
FLEXIWATT27
ORDERING NUMBER: TDA7563
DESCRIPTION
The TDA7563 is a new BCD technology Quad
Bridge type of car radio amplifier in Flexiwatt27
package specially intended for car radio applica-
tions. Thanks to the DMOS output stage the
TDA7563 has a very low distortion allowing a clear
powerful sound. Among the features, its superior
efficiency performance coming from the internal ex-
clusive structure, makes it the most suitable device
to simplify the thermal management in high power
sets.The dissipated output power under average
listening condition is in fact reduced up to 50%
when compared to the level provided by conven-
tional class AB solutions.This device is equipped
with a full diagnostics array that communicates the
status of each speaker through the I2C bus.

– To avoid momentary re-circulation spikes from giving erroneous diagnostics, a check of the output sta-
tus is made after 1ms: if normal situation (no overloads) is detected, the diagnostic is not performed and
the channel returns back active.
– Instead, if an overload is detected during the check after 1 ms, then a diagnostic cycle having a duration
of about 100 ms is started.
– After a diagnostic cycle, the audio channel interested by the fault is switched to RESTART mode. The
relevant data are stored inside the device and can be read by the microprocessor. When one cycle has
terminated, the next one is activated by an I2C reading. This is to ensure continuous diagnostics
throughout the car-radio operating time.
– To check the status of the device a sampling system is needed. The timing is chosen at microprocessor
level (over half a second is recommended).

OUTPUT DC OFFSET DETECTION
Any DC output offset exceeding +/- 2 V are signalled out. This inconvenient might occur as a consequence of
initially defective or aged and worn-out input capacitors feeding a DC component to the inputs, so putting the
speakers at risk of overheating.
This diagnostic has to be performed with low-level output AC signal (or Vin = 0).
The test is run with selectable time duration by microprocessor (from a "start" to a "stop" command):
– START = Last reading operation or setting IB1 - D5 - (OFFSET enable) to 1
