TB2902HQ информация о продукте

The TB2902HQ is 4ch audio amplifier for car audio application. 

This IC can generate high power, high quality sound output, POUT MAX = 41 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, mute function, and various Protection feature are included. 

• High power output
: POUT MAX (1) = 41 W (typ.)
 (VCC = 14.4 V, f = 1 kHz, JEITA max, RL = 4 Ω)
: POUT MAX (2) = 37 W (typ.)
 (VCC = 13.7 V, f = 1 kHz, JEITA max, RL = 4 Ω)
: POUT MAX (3) = 70 W (typ.)
 (VCC = 14.4 V, f = 1 kHz, JEITA max, RL = 2 Ω)
: POUT (1) = 27 W (typ.)
 (VCC = 14.4 V, f = 1 kHz, THD = 10%, RL = 4 Ω)
: POUT (2) = 23 W (typ.)
 (VCC = 13.2 V, f = 1 kHz, THD = 10%, RL = 4 Ω)
: POUT (3) = 45 W (typ.)
 (VCC = 14.4 V, f = 1 kHz, THD = 10%, RL = 2 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 to 20 kHz, RL = 4 Ω)
• Built in stand by & muting function: controlled via I2C Bus (pin 16)
• 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) = 9 to 18 V (RL = 4 Ω)VCC (opr) = 9 to 16 V (RL = 2 Ω)
