9 / 10 page LA6558 No.6504-9/10 Relation of MUTE and Power (P-VCC) * Connect S-VCC and P-VCC externally. * Connect P-GND and S-GND externally. Various MUTE functions and output, 3.3V REG operation condition CH1, 2, 4, 5 (BTL-AMP) CH3, 6 (LOADING) 3.3VREG 5VREG With IN-MUTE: L OFF - OFF With thermal shutdown operating OFF OFF OFF With VREF lowering (0.7V or less) OFF - - * (-) indicates no-operation for functions to which MUTE, thermal shutdown, and VREF lowering correspond. * IN-MUTE operates for BTL-AMP (CH1, 2, 4, and 5) and 3.3VREF and 5 VREF. * VREF lowering is effective for BTL-AMP only. Operative for ((MUTE operation)) to BTL-AMP(CH1, 2, 4, 5) and 3.3VREF, 5VREF IN-MUTE condition BTL-AMP (CH1, 2, 4, 5) 3.3VREG 5VREG H ON L OFF Operative for ((VREF lowering)) to BTL-AMP VREF condition BTL-AMP (CH1, 2, 4, 5) VREF > 0.7(V) ON VREF < 0.7(V) OFF LOADING Block VIN*+ (FWD) VIN*- (REV) Loading output L Brake L H Reversed (VO=-1.5×REV) *1 L Forward (VO= 1.5×FWD) *1 H H (VO=1.5×(VFO-VRE)) * When the brake is applied, each “+” and “-” output voltage becomes VCC/2. *1 FWD: VIN6+, VIN3+, REV: VIN6-, VIN3-. * L voltage is L<VF(≈0.6V). * Gain of loading (CH3, 6) is 3.5dB(TYP).
