The TB2929HQ is a four-channel BTL power amplifier for car audio applications.

BTL, which stands for “Bridge-Tied Load,” is a configuration commonly used in power amplifiers. A BTL power amplifier is designed to deliver a higher power output to a load (typically a speaker) by utilizing a bridge-tied load arrangement. This configuration allows for increased power without the need for a higher supply voltage.

This IC has a pure complementary P-ch and N-ch DMOS output stage, offering maximum output power (POUT MAX) of 45 W. It includes a standby switch, mute function and various
protection features.



0. High output power

1. Standby switch (pin 4)

2. Mute function (pin 22)

3. Built-in AUX amplifier from single input to 2 channels output (pin 25)

4. Various protection features

Standby Switch (pin 4) :

The power supply can be turned on or off via pin 4 (Stby). The threshold voltage of pin 4 is
set at about 3 VBE (typ.). The power supply current is about 0.01 μA (typ.) in the standby state.
