TB2926HQ
TOSHIBA Bi-CMOS Linear Integrated Circuit Silicon Monolithic
TB2926HQ
45 W × 4-ch BTL Audio Power IC
The TB2926HQ is a four-channel BTL power amplifier for car
audio applications.
This IC has a pure complementary P-ch and N-ch DMOS output
stage, offering maximum output power (POUT MAX) of 45 W.
It includes a standby switch, mute function and various
protection features.
Features
High output power
POUT MAX (1) = 45 W (typ.)
(VCC = 15.2 V, f = 1 kHz, JEITA max, RL = 4 )
Weight: 7.7 g (typ.)
POUT MAX (2) = 43 W (typ.)
(VCC = 14.4 V, f = 1 kHz, JEITA max, RL = 4 )
POUT (1) = 26 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 )
Low THD: 0.007% (typ.) (VCC = 13.2 V, f = 1 kHz, POUT = 5 W, RL = 4 )
Low noise: VNO = 60 µVrms (typ.)
(VCC = 13.2 V, Rg = 0 , BW = 20 Hz to 20 kHz, RL = 4 )
Standby switch (pin 4)
Mute function (pin 22)
Output DC offset detection (pin 25)
Various protection features
Thermal overload; overvoltage; output short-circuits to GND, VCC and across the load; speaker current limiting
Operating supply voltage: VCC (opr) = 8.0 to 18 V (RL = 4 )
Note 1: Install the device correctly. Otherwise, the device or system may be degraded, damaged or even destroyed.
Note 2:
The protection features are intended to avoid output short-circuits or other abnormal conditions temporarily. It
is not guaranteed that they will prevent the IC from being damaged.
Exposure to conditions beyond the guaranteed operating ranges may not activate the protection features,
resulting in an IC damage due to output short-circuits.

Detailed Description
1. Standby Switch (pin 4)
The power supply can be turned on or off via
pin 4 (Stby). The threshold voltage of pin 4 is
set at about 3 VBE (typ.). The power supply
current is about 0.01 µA (typ.) in the standby
state.

Benefits of the Standby Switch
(1) VCC can be directly turned on or off by a microcontroller, eliminating the need for a switching relay.
(2) Since the control current is minuscule, a low-current-rated switching relay can be used.
