TB2902HQ  
TOSHIBA Bi-CMOS Digital Integrated Circuit Silicon Monolithic  
TB2902HQ  
Maximum Power 41 W BTL × 4-ch Audio Power IC  
The TB2902HQ is 4ch audio amplifier for car audio application.  
This IC can generate high power, high quality sound output,  
P

MAX = 41 W, using a pure complementary P-ch and N-ch  
DMOS output stage.  
The built-in self diagnosis function which is included can be  
controlled via I2C BUS.  
In addition, stand-by and mute function, and various  
Protection feature are included.

Note 1: Install the product correctly. Otherwise, it may result in break down, damage and/or degradation to the  
product or equipment.  
Note 2: These protection functions are intended to avoid some output short circuits or other abnormal conditions  
temporarily. These protect functions do not warrant to prevent the IC from being damaged.  
- In case of the product would be operated with exceeded guaranteed operating ranges, these protection  
features may not operate and some output short circuits may result in the IC being damaged.
