TOSHIBA Bi-CMOS Digital Integrated Circuit Silicon Monolithic
TB2913HQ
Maximum Power 47 W BTL × 4-ch Audio Power IC
The TB2913HQ is 4-ch BTL audio amplifier for car audio applications.
This IC can generate higher power: POUT MAX = 47 W as it
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, Clip detector is built in.

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
