TOSHIBA Bi-CMOS Linear Integrated Circuit Silicon Monolithic
TB2921AHQ
51 W
× 4-ch BTL Audio Power IC
The TB2921AHQ 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 5１ W.
It includes a standby switch, mute function, a high-side switch
and various protection features.
Features
High output power
POUT MAX (1) = 51 W (typ.)
(VCC = 15.2 V, f = 1 kHz, JEITA max, RL = 4 Ω)
POUT MAX (2) = 45 W (typ.)
(VCC = 13.7 V, f = 1 kHz, JEITA max, RL = 4 Ω)
POUT MAX (3) = 80 W (typ.)
(VCC = 14.4 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 THD: 0.005% (typ.) (VCC = 13.2 V, f = 1 kHz, POUT = 5 W, RL = 4 Ω)
Low noise: VNO = 55 μVrms (typ.)
(VCC = 13.2 V, Rg = 0 Ω, BW = 20 Hz to 20 kHz, RL = 4 Ω)
Standby switch (pin 4)
Mute function (pin 22)
High-side switch (H-SW) (pin 25)
Various protection features
Thermal overload; overvoltage; output short-circuits to GND, VCC and across the load
Operating supply voltage : VCC (opr) = 8.0 to 18 V (RL = 4 Ω)
: VCC (opr) = 8.0 to 16 V (RL= 2 Ω)
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.
Note 3: The protection circuit may malfunction depending on the connected speaker type due to a phase shift. The
operation of the device should therefore be verified by actually connecting a speaker to its outputs. It is not
recommended to connect a 2-ohm load such as a subwoofer that induces a significant phase shift, and that
special care should be taken in such cases.
Weight: 7.7 g (typ.)
