TB2921HQ  
TOSHIBA Bi-CMOS Linear Integrated Circuit Silicon Monolithic  
TB2921HQ (preliminary)  
Maximum Power 50 W BTL × 4-ch Audio Power IC  
The TB2921HQ is 4-ch BTL audio amplifier for car audio  
applications.  
This IC can generate higher power: P  
MAX =50 W as it  
OUT  
includes the pure complementary P-ch and N-ch DMOS output  
stage.  
It is designed to yield low distortion ratio for 4-ch BTL audio  
power amplifier, built-in standby function, muting function, and  
various kinds of protectors.  
Additionally, high-side switch is built in.  
Weight: 7.7 g (typ.)

Note 1: Since this device’s pins have a low withstanding voltage, please handle it with care.  
Note 2: Install the product correctly. Otherwise, it may result in break down, damage and/or degradation to the  
product or equipment.  
Note 3: 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.  
Note 4: The protection circuit may operate not correctly in case of the use of large phase-shift type speaker.  
Therefore, it should be confirmed that there is no problem on actual evaluation or mass-production board.  
Especially, it is necessary to be ware such a behavior when the large phase-shift type 2ohm load, which is  
a kind of sub-woofer for example, is connected to this IC, though such kind of speaker use is not  
recommended.
