TB2921HQ Maximum Power 50 W BTL X 4-ch Audio Power-IC

TB2921HQ Maximum Power 50 W BTL X 4-ch Audio Power-IC

is made only on the single channel.) 1. Standby SW Function (pin 4) By means of controlling pin 4 (standby pin) to High and Low, the power supply can be set to ON and OFF. The threshold voltage of pin 4 is set at about 3VBE (typ.), and the power supply current is about 2 µA (typ.) in the standby state. VCC ON Power OFF 4 10 kΩ ≈ 2 VBE to BIAS CUTTING CIRCUI.

Features

• High power output : POUT MAX (1) = 50 W (typ.) (VCC = 15.2 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)
