Application Information
1. Thermal Shutdown
The TSD circuit is activated at the junction temperature of 160
°
C
and
deactivated at 135
°
C
with the hysteresis of 25
°
C
. During the thermal
shutdown, the TSD circuit keeps all the output driver off.
2. CH Mute Function
When the mute pin is high, the TR Q1 is on and Q2 is off, so the bias
circuit is enabled. When the mute pin is low (GND), the TR Q1 is off
and Q2 is on, so the bias circuit is disabled.
During the mute on state, all the circuit blocks except for the variable
regulator remain off, and the low power quiescent state is established.
Truth table is as follows;
Pin 19, 20, 21
Mute
High
Mute-Off
Low
Mute-On
3. Power Save Function
When the pin39 is high, the TR Q3 becomes on and Q4 off, so the bias
circuit is enabled. When the pin39 is low (GND) , the TR Q3 becomes
off and Q4 is on, so the bias circuit is disabled.
During the power save on state, this function keeps all the circuit
blocks off, and the low power quiescent state is established.
Truth table is as follows;
Pin39
Power Save
High
Power Save Off
Low
Power Save On
4. TDS Monitor Function
Pin22 is TSD monitor pin, which detects
the state of the TSD block
and generates the TSD-monitor signal.
In the normal state Q5 is on, and Q6 is off. When the TSD block is
activated Q5 becomes off, and thus the voltage of pin22 keeps low.
Truth table is as follows;
