Application Information
1. THERMAL SHUTDOWN
When the chip temperature reaches to 175
°
C, then the TSD circuit is
activated.
This shuts down the bias current of the output drivers, and all the
output drivers are in cut-off state. Thus the chip temperature begins to
decrease.
when the chip temperature falls to 150
°
C, the TSD circuit is
deactivated and the output drivers are normally operated.
The TSD circuit has the hysteresis temperature of 25
°
C.
2. ALL MUTE FUNCTION
When the pin22 is high, the TR Q1 is turned on and Q2 is off, so the
bias circuit is enabled. On the other hand, when the pin22 is Low
(GND) , the TR Q1 is turned off and Q2 is on, so the bias circuit is
disabled.
This function will cause all the output drivers to be in mute state.
Truth table is as follows;
Pin#22

HIGH
MUTE-OFF
LOW
MUTE-ON
3. POWER SAVE FUNCTION
When the pin21 is high, the TR Q3 is turned on and Q4 is off, so the
bias circuit is enabled. On the other hand, when the pin21 is Low
(GND) , the TR Q3 is turned off and Q4 is on, so the bias circuit is
disabled.
That is, this function will cause all the circuit blocks of the chip except
for the variable regulator to be in the off state. thus the low power
quiescent state is established
