TB2901HQ

TB2901HQ(O) TOSHIBA Bi-CMOS Digital Integrated Circuit Silicon Monolithic TB2901HQ Maximum Power 47 W BTL × 4-ch Audio Power IC The TB2901HQ is 4-ch BTL audio amplifier for car audio applications. This IC can generate higher power: POUT MAX = 47 W as it includes the pure complementary P-ch and N-ch DMOS output stage. www.DataSheet4U.com It is designed to yield low distortion ratio for 4-ch BTL audio power amplifier, built-in standby function, muting function, and various kinds of protectors. Additionally, high-side switch is built in. Weight: 7.7 g (typ.) Features High power output : POUT MAX (1) = 47 W (typ.) (VCC = 14.4 V, f = 1 kHz, JEITA max, RL = 4 Ω) : POUT MAX (2) = 43 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 = 2 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 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~20 kHz, RL = 4 Ω) Built-in standby switch function (pin 4) Built-in muting function (pin 22) Built-in high-side switch function (pin 25) Built-in various protection circuits: Thermal shut down, overvoltage, out to GND, out to VCC, out to out short Operating supply voltage: VCC (opr) = 9~18 V (RL = 4 Ω) Note 1: Since this device’s pins have a low withstanding vo...
