The LM4651 is a fully integrated conventional pulse width  
modulator driver IC. The IC contains short circuit, under volt-  
age, over modulation, and thermal shut down protection cir-  
cuitry. The LM4651also contains a standby function which  
shuts down the pulse width modulation minimizing supply  
current. The LM4652 is a fully integrated H-bridge power  
MOSFET IC in a TO-220 power package. The LM4652 has a  
temperature sensor built in to alert the LM4651 when the die  
temperature of the LM4652 exceeds the threshold. Together,  
these two IC's form a simple, compact high power audio am-  
plifier solution complete with protection normally seen only in  
Class AB amplifiers. Few external components and minimal  
traces between the IC's keep the PCB area small and aids in  
EMI control.

Externally controswiing frequency.  
50kHz to 0kHz swifrequency range.  
Integraor amp and feedback amp.

erny controllable output current limiting and thermal  
swn pection.  
Self g protection diagnostic.  
■
The near rail-to-rail switching amplifier substantially increases  
the efficiency compared to Class AB amplifiers. This high ef
ficiency solution significantly reduces the heat sink size com-  
pared to a Class AB IC of the same power level. This two
solution is optimum for powered subwoofers and self
speakers.  
Applications  
red subwoofers for home theater and PC's

Car booster amplifier  
Self-powered speakers
