TB2939HQ

TB2939HQ TOSHIBA Bi-CMOS Linear Integrated Circuit Silicon Monolithic TB2939HQ(TENTATIVE) 45W × 4-ch BTL Audio Power IC The TB2939HQ 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 45 W. It includes a standby switch, mute function and various protection features. Features High output power POUT MAX (1) = 45 W (typ.) (VCC = 15.2 V, f = 1 kHz, JEITA max, RL = 4 Ω) POUT MAX (2) = 41 W (typ.) (VCC = 14.4 V, f = 1 kHz, JEITA max, RL = 4 Ω) POUT (1) = 24 W (typ.) (VCC = 14.4 V, f = 1 kHz, THD = 10%, RL = 4 Ω) POUT (2) = 21 W (typ.) (VCC = 13.2 V, f = 1 kHz, THD = 10%, RL = 4 Ω) Weight: 7.7 g (typ.) Low THD: 0.007% (typ.) (VCC = 13.2 V, f = 1 kHz, POUT = 5 W, RL = 4 Ω) Low noise: VNO = 60 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) Built-in diagnosis circuit include output DC offset detection (pin 25) Various protection features Thermal overload; overvoltage; output short-circuits to GND, VCC and across the load; speaker current limiting Operating supply voltage: VCC (opr) = 8.0 to 18 V (RL = 4 Ω) http://www.DataSheet4U.com/ 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.
