49 W × 4-ch BTL Audio Power IC

Description:
The TB2926CHQ 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 49 W.
It includes a standby switch, mute function and various protection features.

Features :
• High output power
• POUT MAX (1) = 49 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)
• 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)
