TB2902HQ

Maximum Power 41 W BTL × 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

• High power output

: POUT MAX (1) = 41 W (typ.)

(VCC = 14.4 V, f = 1 kHz, JEITA max, RL = 4 Ω)

: POUT MAX (2) = 37 W (typ.)

(VCC = 13.7 V, f = 1 kHz, JEITA max, RL = 4 Ω)

: POUT MAX (3) = 70 W (typ.)

(VCC = 14.4 V, f = 1 kHz, JEITA max, RL = 2 Ω)

: POUT (1) = 27 W (typ.)

(VCC = 14.4 V, f = 1 kHz, THD = 10%, RL = 4 Ω)

: POUT (2) = 23 W (typ.)

(VCC = 13.2 V, f = 1 kHz, THD = 10%, RL = 4 Ω)

: POUT (3) = 45 W (typ.)

(VCC = 14.4 V, f = 1 kHz, THD = 10%, RL = 2 Ω)

Weight: 7.7 g (typ.)

• Low distortion ratio: THD = 0.015% (typ.)

(VCC = 13.2 V, f = 1 kHz, POUT = 5 W, RL = 4 Ω)

• Low noise: VNO = 90 µVrms (typ.)

(VCC = 13.2 V, Rg = 0 Ω, BW = 20 Hz to 20 kHz, RL = 4 Ω)

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

• Built in clipping detection (pin 4)

• 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)

• 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

• Operating supply voltage: VCC (opr) = 9 to 18 V (RL = 4 Ω)

VCC (opr) = 9 to 16 V (RL = 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.
