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
muted.
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
muted.
2. TSD (THERMAL SHUTDOWN)
The V
REF BG
is the output voltage of the band-gap-referenced biasing circuit and acts as the input voltage of the TSD
circuit.
The base-emitter voltage of the TR, Q11 is designed to turn-on at below voltage.

R12 / (R11 + R12) = 460mV
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.
