Application Information
1. Mute Function
When the mute (pin 7) is high level, the bias circuit of BTL driver is activated. On the other hand, when the mute (pin7) is
open or low level, the bias circuit of BTL driver is disabled. So that the 4-channels BTL driver output circuit will be muted.
2. TSD (Thermal Shutdown) Function
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 transistor, 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.
Hence, the Q11 would turn on so the output circuit will be muted. The TSD circuit has the hysteresis temperature of 25
°
C.
3. OP-AMP
General OP-amplifier is integrated in the IC for user’s convenience.
