TOSHIBA Bi-CMOS Linear Integrated Circuit
Silicon Monolithic
TB2932HQ (TENTATIVE)
Maximum Power 43 W BTL
× 4-ch Audio Power IC
The TB2932HQ is 4ch audio amplifier for car audio application.
This IC can generate high power, high quality sound output,
POUT MAX = 43 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) = 43 W (typ.)
P (VCC = 15.2 V, f = 1 kHz, JEITA max, RL = 4 )
: POUT MAX (2) = 41 W (typ.)
(VCC = 14.4 V, f = 1 kHz, JEITA max, RL = 4 )
: POUT MAX (3) = 70 W (typ.)
(VCC = 14.4 V, f = 1 kHz, JEITA max, RL = 2 )
: POUT (1) = 27 W (typ.)
(VCC = 14.4 V, f = 1 kHz, THD = 10%, RL = 4 )
: POUT (2) = 23 W (typ.)
(VCC = 13.2 V, f = 1 kHz, THD = 10%, RL = 4 )
: POUT (3) = 45 W (typ.)
(VCC = 14.4 V, f = 1 kHz, THD = 10%, RL = 2 )
Low distortion ratio:
THD = 0.007% (typ.)
(VCC = 13.2 V, f = 1 kHz, POUT = 5 W, RL = 4 )
Low noise: VNO = 60 Vrms (typ.)
(VCC = 13.2 V, Rg = 0 , BW = 20 Hz to 20 kHz, RL = 4 )
Built in stand by & muting function: controlled via I2C Bus (26/12dB)
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) = 8 to 18 V (RL = 4 )
VCC (opr) = 8 to 16 V (RL = 2 )
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.
Weight: 7.7 g (typ.)
