The TB2932HQ is 4ch audio amplifier for car audio application. This IC can generate high power, high quality sound output, POUT 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 protecton feature are included.
