TB2913HQ

Maximum Power 47 W BTL × 4-ch Audio Power IC

The TB2913HQ is 4-ch BTL audio amplifier for car audio applications.

This IC can generate higher power: POUT MAX = 47 W as it

includes the pure complementary P-ch and N-ch DMOS output

stage.

It is designed to yield low distortion ratio for 4-ch BTL audio

power amplifier, built-in standby function, muting function, and

various kinds of protectors.

Additionally, Clip detector is built in.

Features

• High power output

: POUT MAX (1) = 47 W (typ.)

Weight: 7.7 g (typ.)

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

: POUT MAX (2) = 43 W (typ.)

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

: POUT (1) = 29 W (typ.)

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

: POUT (2) = 25 W (typ.)

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

• 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~20 kHz, RL = 4 Ω)

• Built-in standby switch function (pin 4)

• Built-in muting function (pin 22)

• Built-in Clip-detection function (pin 25)

• Built-in various protection circuits:

Thermal shut down, overvoltage, out to GND, out to VCC, out to out short

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

Note 1: Since this device’s pins have a low withstanding voltage, please handle it with care.

Note 2: Install the product correctly. Otherwise, it may result in break down, damage and/or degradation to the

product or equipment.

Note 3: 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
