TB2932HQ
Maximum Power 49 W BTL × 4-ch Audio Power IC
The TB2932HQ is 4ch audio amplifier for car audio application.
This IC can generate high power, high quality sound output,
P_OUT MAX = 49 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.

tweeter or speaker open detection (pin 22 and 25)
• Built-in various protection circuits (Note 1, Note 2)
Thermal shut down, over-voltage, out to GND, out to V_CC, out to out short circuit
• Operating supply voltage: V_{CC (opr)} = 8 to 18 V (R_L = 4 Ω)
V_{CC (opr)} = 8 to 16 V (R_L = 2 Ω)
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.
