Middle Power Class-D Speaker Amplifiers  
Class-D Speaker Amplifier  
for Digital Input with Built-in DSP  
BM5446EFV  
No.10075EBT13  
Description  
BM5446EFV is a Class D Speaker Amplifier with built-in DSP (Digital Sound Processor) designed for Flat-panel TVs in  
particular for space-saving and low-power consumption, delivers an output power of 20W+20W. This IC employs  
state-of-the-art Bipolar, CMOS, and DMOS (BCD) process technology that eliminates turn-on resistance in the output power  
stage and internal loss due to line resistances up to an ultimate level. With this technology, the IC can achieve high  
efficiency of 86% (10W+10W output with 8load). In addition, the IC is packaged in a compact reverse heat radiation type  
power package to achieve low power consumption and low heat generation and eliminates necessity of external heat-sink  
up to a total output power of 40W. This product satisfies both needs for drastic downsizing, low-profile structures and many  
function, high quality playback of sound system.  
Features  
1) This IC includes the DSP (digital sound processor) for Audio signal processing for Flat TVs.  
2) This IC has two input systems of digital audio interface.  
(I2S/LJ/RJ format, LRCLK: 32 kHz/ 44.1kHz / 48kHz, SYS_CLK: 256fs / 512fs,  
BCLK: 48fs / 64fs, SDATA: 16 / 20 / 24bit)  
3) With wide range of power supply voltage, it is possible to operate with single power supply. (Vcc = 10~26V)  
4) With high efficiency and low heat dissipation contributing to miniaturization, slim design, and also power saving of the  
system.  
5) S/N of the system can be optimized by adjusting the gain selection in 16 steps. (20~35dB,1dB/step)  
6) With built-in feedback circuitry at the output, prevents the decrease in sound quality due to change in power supply  
voltage. In addition, low noise and low distortion are achieved.  
7) With a built-in DAC provides best stereo-output for headphone function. As a result, the selection of output of the  
digital input in two systems is possible.  
8) It has additional S/PDIF output for the LINE output usage.  
9) Eliminates pop-noise generated during the power supply on/off. High quality muting performance is realized by using  
the soft-muting technology.  
10) This IC is built-in with various protection functions for highly reliability design.  
(High temperature protection, Under voltage protection, Output short protection, Output DC-Voltage protection and  
Clock stop protection).  
Applications  
Flat Panel TVs (LCD, Plasma), Home Audio, Desktop PC, Amusement equipments, Electronic Music equipments, etc.
