TB2904HQ
TB2904HQ is Maximum Power 43W BTL 4-ch Audio Power-IC manufactured by Toshiba.
Features - High power output : POUT MAX (1) = 43 W (typ.) P (VCC = 14.4 V, f = 1 k Hz, JEITA max, RL = 4 Ω) : POUT MAX (2) = 39 W (typ.) (VCC = 13.7 V, f = 1 k Hz, JEITA max, RL = 4 Ω) : POUT (1) = 26 W (typ.) (VCC = 14.4 V, f = 1 k Hz, THD = 10%, RL = 4 Ω) : POUT (2) = 23 W (typ.) (VCC = 13.2 V, f = 1 k Hz, THD = 10%, RL = 4 Ω) Low distortion ratio: THD = 0.015% (typ.) (VCC = 13.2 V, f = 1 k Hz, POUT = 5 W, RL = 4 Ω) Low noise: VNO = 90 µVrms (typ.) (VCC = 13.2 V, Rg = 0 Ω, BW = 20 Hz to 20 k Hz, RL = 4 Ω) Built-in standby switch function (pin 4) Built-in muting function (pin 22) Built-in Off-set detection function (pin 25) Weight: 7.7 g (typ.) - - - - - - - Built-in various protection circuits: Thermal shut down, overvoltage, out to GND, out to VCC, out to out short, speaker burned Operating supply voltage: VCC (opr) = 9 to 18 V (RL = 4 Ω) Note 1: Since this device’s pins have a low withstanding voltage, please handle it with care. Note 2: Install the product correctly. Otherwise, it may result in break down, damage and/or degradation to the product or equipment. Note 3: 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. 2004-03-26 TB2904HQ(o) Block Diagram C5 1 TAB 20 VCC1 6 VCC2 OUT1 (+) 9 C1 IN1 PW-GND1 8 OUT1 (- ) 7 RL OUT2 (+) 12 IN2 5 RL C1 PW-GND2 2 OUT2 (- ) 3 C6 16 AC-GND OUT3 (+) 15 IN3 PW-GND3 18 OUT3 (- ) 19 RL C1 OUT4 (+) 14 IN4 21 RL C1 PW-GND4 24 OUT4 (- ) 23 PRE-GND 13 RIP 10 C2 STBY 4 OFF-SET MUTE DET 25 22 C4 R1 5V PLAY MUTE : PRE-GND : PW-GND Note: Some of the functional blocks, circuits, or constants in the block diagram may be omitted or simplified for explanatory...
