FUNCTIONAL DESCRIPTION
The TDA1562 contains a mono class-H BTL output power
amplifier. At low output power, up to 18 W, the device
operates as a normal BTL amplifier. When a larger output
voltage swing is required, the internal supply voltage is
lifted by means of the external electrolytic capacitors. Due
to this momentarily higher supply voltage the obtainable
output power is 70 W.
In normal use, when the output is driven with music-like
signals, the high output power is only needed during a
small percentage of time. Under the assumption that a
music signal has a normal (Gaussian) amplitude
distribution,thereductionindissipationisabout50%when
compared to a class-B output amplifier with the same
output power. The heatsink should be designed for use
with music signals. If the case temperature exceeds
120 °C the device will switch back from class-H to class-B
operation. The high power supply voltage is then disabled
and the output power is limited to 20 W.
When the supply voltage drops below the minimum
operating level, the amplifier will be muted immediately.
Mode select input (pin MODE)
This pin has 3 modes:
1. LOW for standby: the complete circuit is switched off,
the supply current is very low
2. MID for mute: the circuit is switched on, but the input
signal is suppressed
3. HIGH for on: normal operation, the input signal is
amplified by 26 dB.
When the circuit is switched from mute to on or vice versa
the actual switching takes place at a zero crossing of the
input signal. The circuit contains a quick start option, i.e.
when it is switched directly from standby to on, the
amplifier is fully operational within 50 ms (important for
applications like car telephony and car navigation).

INPUT
This input has 3 possibilities:
1. LOWforfastmute:thecircuitremainsswitchedon,but
the input signal is suppressed
2. MID for class-B: the circuit operates as class-B
amplifier, the high power supply voltage is disabled,
independent of the case temperature
3. HIGH for class-H: the circuit operates as class-H
amplifier, the high power supply voltage is enabled,
independent of the case temperature.
When the circuit is switched from fast mute to class-B/H or
vice versa the switching is immediately carried out. When
thecircuit is switched from class-Bto class-H or vice versa
the actual switching takes place at a zero crossing of the
input signal.
OUTPUT
This output has 3 possibilities:
1. LOW for mute: acknowledge of muted amplifier
2. MID for class-B: the circuit operates as class-B
amplifier, the high power supply voltage is disabled,
caused by the case temperature Tc> 120 °C
3. HIGH for class-H: the circuit operates as class-H
amplifier, the high power supply voltage is enabled,
because the case temperature Tc< 120 °C.
Whenthecircuitisswitchedfromclass-Btoclass-Horvice

of the input signal.
The status I/O pins of maximum 8 devices may be tied

Diagnostic output (pin DIAG)
DYNAMIC DISTORTION DETECTOR (DDD)
At the onset of clipping of the output stages, the DDD
becomes active. This information can be used to drive a
sound processor or DC-volume control to attenuate the
input signal and so limit the distortion.
SHORT-CIRCUIT PROTECTION
When a short-circuit occurs at the outputs to ground or to
the supply voltage, the output stages are switched off.
They will be switched on again approximately 20 ms after
removing the short-circuit. During this short-circuit
condition the diagnostic output is continuously LOW.
When a short-circuit occurs across the load, the output
stages are switched off during approximately 20 ms. After
that time is checked during approximately 50 µs whether
the short-circuit is still present. During this short-circuit
condition the diagnostic output is LOW for 20 ms and
HIGH for 50 µs. The power dissipation in any short-circuit
condition is very low.

TDA1562SD
TEMPERATURE DETECTION
Justbeforethetemperatureprotection becomes active the
diagnostic output becomes continuously LOW.
LOAD DETECTION
Directly after the circuit is switched from standby to mute
or on, a built-in detection circuit checks whether a load is
present. The results of this check can be detected at the
diagnosticoutput,byswitchingthemodeselectinputinthe
mute mode.
Since the diagnostic output is an open-collector output,
more devices can be connected.
