Application Information
1. Thermal Shutdown
When the chip temperature reaches to 160
°
C by abnormal condition,
then the TSD circuit is activated.
This shut down the bias current of the output drivers, and all the
output drivers are in cut-off state. Thus the chip temperature begin to
decrease.
when the chip temperature falls to 135
°
C, the TSD circuit is
deactivated and the output drivers are normally operated.
The TSD circuit has the hysteresis temperature of 25
°
C.
2. CH MUTE Function
When the pin21,22 is high, the TR Q1 is turned on and Q2 is off, so
the bias circuit is enabled. On the other hand, when the pin21,22 is
Low (GND) , the TR Q1 is turned off and Q2 is on, so the bias circuit
is disabled.
That is, this function will cause all the output drivers to be in mute
state.
Truth table is as follows;

High
Mute-Off
Low
Mute-On
3. Power Save Function
When the pin38 is high, the TR Q3 is turned on and Q4 is off, so the
bias circuit is enabled. On the other hand, when the pin38 is Low
(GND) , the TR Q3 is turned off and Q4 is on, so the bias circuit is
disabled.
That is, this function keeps all the circuit blocks of the chip off , thus
the low power quiescent state is established
Truth table is as follows;
