Bi-CMOS Linear Integrated Circuit Silicon Monolithic
TB2959HQ
Maximum Power 47W BTL
 4-ch Audio Power IC
1. Description
The TB2959HQ 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 47W.
It includes a standby switch, mute function and various
protection features.
2. Applications
Power IC developed for car audio applications.
3. Features
 High output power, low distortion, and low noise property (for details, refer to the Table 1)
 Build-in AUX-IN (pin25)
 Built-in various mute functions (low voltage, standby on/off)
 Built-in standby switch (pin4)
 Built-in mute switch (pin22)
 Built-in various protection circuits (thermal shut down, over-voltage, short to GND, short to VCC, and output to
output short)
Note1: Typical test conditions: VCC = 13.2 V, f = 1 kHz, RL = 4 Ω, GV = 26 dB, Ta = 25°C; unless otherwise specified.
Note2: Rg: signal source resistance
Weight: 7.7 g (typ.)
