LV47009P
Monolithic Linear IC
For Car Audio Systems
4-Channel BTL Power Amplifier
Overview
The LV47009P is the IC for 4-channel BTL power amplifier that is developed for car audio system.
Pch DMOS in the upper side of the output stage and Nch DMOS in the lower side of the output stage are complimentary.
High power and high quality sound are realized by that.
This IC incorporate various functions (standby switch, muting function, and various protection circuit) necessary for car
audio system. Also, it has a self-diagnosis function.
Functions
High output : PO max = 41W (typical) (VCC = 15.2V, f = 1kHz, JEITA max, RL = 4Ω)
: PO max = 24W (typical) (VCC = 14.4V, f = 1kHz, THD = 10%, RL = 4Ω)
: PO max = 17W (typical) (VCC = 14.4V, f = 1kHz, THD = 1%, RL = 4Ω)
Built-in muting function (pin 22)
Built-in Standby switch (pin 4)
Built-in Self-diagnosis function (pin 25) :
Signal output in case of output Clip detection, shorting to VCC, shorting to ground, and load shorting.
Electric mirror noise decrease
Built-in various protection circuit (shorting to ground, shorting to VCC, load shorting, over voltage and thermal shut
down)
No external anti-oscillation part necessary.
Note 1 : Please do not mistake connection.
A wrong connection may produce destruction, deterioration and damage for the IC or equipment.
Note 2 : The protective circuit function is provided to temporarily avoid abnormal state such as incorrect output connection.
But, there is no guarantee that the IC is not destroyed by the accident.
The protective function do not operate of the operation guarantee range. If the outputs are connected incorrectly, IC
destruction may occur when used outside of the operation guarantee range.
Note 3 : External parts, such as the anti-oscillation part, may become necessary depending on the set condition. Check their
necessity for each set.

3. ACGND pin (pin 16)
The capacitor of the pin 16 must use the same capacitance value as the input capacitor.
Also, connect to the same PREGND as the input capacitor.
4. Self-diagnostics function (pin 25)
This function can detect of the unusual state.
(1) Shorting to VCC/Shorting to ground
(2) Load shorting
(3) Output clip detection
: The pin 25 becomes the low level.
: The pin 25 is alternated between the low level and the high level
according to the output signal.
: when the output voltage clip, the pin 25 becomes the low level.
* Note: The output offset abnormality is thought of as the leakage current of the input capacitor.
In addition, the pin 25 has become the NPN open collector output (active low).
The pin 25 must be left open when this function is not used.
