TB2923HQ 50 W X 4-ch BTL Audio Power-IC

TB2923HQ 50 W X 4-ch BTL Audio Power-IC

1. Standby Switch (pin 4) The power supply can be turned on or off via pin 4 (Stby). The threshold voltage of pin 4 is set at about 3 VBE (typ.). The power supply current is about 0.01 µA (typ.) in the standby state. VCC ON OFF Power 4 10 kΩ ≈ 2 VBE to Bias filter network Standby Control Voltage (VSB): Pin 4 Standby ON OFF Power OFF ON VSB (V) 0 to 0.9 2.9 .
