Bi-CMOS LSI
Class-D Audio Power Amplifier
BTL 15W × 2ch
http://onsemi.com
Overview
The LV49152V is a 15W per channel stereo digital power amplifier that takes analog inputs. The LV49152V uses
unique Our developed feedback technology to achieve excellent audio quality despite being a class D amplifier and can
be used to implement high quality flat display panel (FDP) based systems.
Features
• BTL output, class D amplifier system
• Unique Our developed feedback technology achieves superb audio quality
• High-efficiency class D amplifier
• Soft muting function reduces impulse noise at power on/off
• Full complement of built-in protection circuits : over current protection, thermal protection, and low power supply
voltage protection circuits
• Built in Power limiter
Functions
• Power
: 15W × 2ch output (VD = 15V, RL = 8Ω, fin = 1kHz, AES17, THD + N = 10%)
• Efficiency : 93% (VD = 15V, RL = 8Ω, fin = 1kHz, PO = 15W)
• THD + N : 0.08% (VD = 15V, RL = 8Ω, fin = 1kHz, PO = 1W, Filter : AES17)
• Noise
: 90μVrms (Filter : A-weight)
• Package SSOP44J (275mil)

Operation Mode Summary
STBY mode (STBY = L and MUTE = L)
Each bias becomes off state when the regulator in IC has been turned off.
The most of circuits becomes off state.
The supply current : 1μA (typical).
MUTE mode (STBY = H and MUTE = L)
Each bias becomes on state when the regulator in IC has been turned on.
When more than half of the circuits are active, the amplifier in the output stages become off.
The supply current : 20mA (typical).
Operation mode (STBY = H and MUTE = H)
The LV49152V operates as D-class amplifier.
The output signal is synchronized with the input signal.
The supply current : 45mA (typical)

Power supply lowering protection circuit
Since the instable operation in the low voltage is prevented by using this circuit, after the voltage of the PVD pin is
monitored and the voltage below the Attack voltage (PVD = 8V typ.), AMP is turned off.
Also, to prevent the instable operation when the voltage of the PVD pin is decreased by any cause during operations, the
Attack voltage (PVD = 7V typ.) is set.
The voltage of Attack and Recover has hysteresis (About 1V) to prevent ON/OFF continuous action of the power supply
lowering protection circuit.
Function image
Also, this IC is designed to turn off AMP in the same sequence that the MUTE is on as a pop noise measures when the
plug of products are put off.
Over current protection circuit
The over current protection circuit is a protection circuit * to protect the output DMOS from the over current and
corresponds to any mode of the power supply, GND and a load short.
The protection operation is performed when the current reaches the detection current value set out in IC and the output
DMOS is compulsorily turned off for about 20μsec.
After compulsorily tuning off the output DMOS, when the Amplifier is automatically reset in usual operation and the over
current flows continuously, the protection operation is performed again.
Function image
* The over current protection circuit is a function to avoid the abnormal state like the output short-circuit temporarily.
Unfortunately, we cannot guarantee that IC is not destroyed.

Thermal protection circuit
The LV49152V includes a thermal protection circuit to prevent damage to or destruction of the IC should abnormal
internal heat generation occur.
This means that should the IC junction temperature (Tj) rise above about 175°C due to inadequate heat dissipation or
other reason, the thermal protection circuit will operate to stop IC operation should the temperature rise further.
If the temperature is reduced by lowering the input level or other means, the thermal protection circuit will recover
automatically (about 105°C).

PLC
The PLC (power level control) function is able to control the maximum index modulation by setting a value of external
PLC resistance R1 voluntarily, and prevent a PWM signal from becoming the over modulation mode. In addition, this
circuit can be use as output power limit circuit because the PLC function can set the maximum index modulation
voluntarily, and variable from 2W to 15W with output power linearly in the state that made the power supply voltage and
load resistance fixation. Because the PLC function can set the suitable rated output with the same power supply
voltage/speaker regardless of screen size in flat screen televisions by this, set can plan the commonization of the board.
Furthermore, The PLC function can reduce abnormal noise in the hard clip so that output wave pattern becomes the soft
clip when it limited output power.

Above formula is common calculation method and is a measure of constant setting.
In fact, it is necessary to set with each set that considers the speaker characteristics.
In addition, please set the fixed number to become Q ≤ 1 in currents in the fc neighborhood increasing if Q value of the LC
filter is big.
