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
OUT
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 I
2
C 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.
