Application Information
1. MUTE
• When the pin7 is open or the voltage of the pin7 is below 0.5V, the mute circuit is activated so that the output circuit is
• When the voltage of the pin7 is above 2V, the mute circuit is deactivated and the output circuit operates normally.
• If the chip temperature rises above 175 C, then the TSD (Thermal Shutdown) circuit is activated and the output circuit is
2. TSD (THERMAL SHUTDOWN)
• The V
• The base-emitter voltage of the TR, Q11 is designed to turn-on at below voltage.
• When the chip temperature rises up to 175 C, then the turn-on voltage of the Q11 would drop down to 460mV.

(Hysteresis: 25 C)
Hence, the Q11 would turn on so the output circuit will be muted.
