TB2946HQ TOSHIBA Bi-CMOS Linear Integrated Circuit Silicon Monolithic TB2946HQ 49 W × 4-ch BTL Audio Power IC The TB2946HQ 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 MAX (3) = 70 W (typ.) (VCC = 14.4 V, f = 1 kHz, JEITA max, RL = 2 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, [ ... ]
