TB2902HQ Datasheet, PDF (1/38 Pages) Toshiba Semiconductor – Maximum Power 41 W BTL × 4-ch Audio Power IC

TOSHIBA Bi-CMOS Digital Integrated Circuit Silicon Monolithic

TB2902HQ

Maximum Power 41 W BTL Ã 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,

POUT 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 I2C BUS.

In addition, stand-by and mute function, and various

Protection feature are included.

Features

â¢ Built in stand by & muting function: controlled via I2C Bus (pin 16)

â¢ Built in clipping detection (pin 4)

â¢ Built in I2C Bus for stand-by, mute, voltage gain control, self diagnosis: Output short detection, offset detection,

tweeter or speaker open detection (pin 22 and 25)

â¢ Built-in various protection circuits (Note 1, Note 2)

Thermal shut down, over-voltage, out to GND, out to VCC, out to out short circuit

â¢ Operating supply voltage: VCC (opr) = 9 to 18 V (RL = 4 â¦)

VCC (opr) = 9 to 16 V (RL = 2 â¦)

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.
