TB2926HQ TOSHIBA Bi-CMOS Linear Integrated Circuit Silicon Monolithic TB2926HQ 45 W × 4-ch BTL Audio Power IC The TB2926HQ 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) = 43 W (typ.) (VCC = 14.4 V, f = 1 kHz, JEITA max, RL = 4 Ω) POUT (1) = 26 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) 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) 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) 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. It is not guaranteed that they will prevent the IC from being damaged. Exposure to conditions beyond the guaranteed operating ranges may not activate the protection features, resulting in an IC damage due to output short-circuits. 1 2006-11-27 TB2926HQ Block Diagram +B C5 C2 10 Ripple 1 TAB 6 VCC2 20 VCC1 9 8 7 Out1 (+) PW-GND1 Out1 (−) C1 11 IN1 C1 12 IN2 5 2 Out2 (+) PW-GND2 Out2 (−) 13 Pre-GND 3 C1 15 IN3 17 18 Out3 (+) PW-GND3 C6 16 AC-GND Out3 (−) 19 C1 [ … ]
