Application information
1. MUTE Function
When the mute pin is low(GND), the TR Q1 is turned on and the bias
circuit is enabled. On the other hand, when the mute pin is high , the TR
Q1 is turned off and the bias circuit is disabled.
Bias Current
CH2,3,4,5
23
It will make all the circuit blocks except CH1 off, so low power quiescent state can be established.
• Truth table is as follows
Pin 23

High
Mute-On
Low
Mute-Off
Q1
2. TSD Function
• When the chip temperature reaches to 175°C by abnormal condition,
the TSD circuit is activated
• This makes the bias current of the output drivers shut down, and all
the output drivers are on cut-off state. Therefore the chip temperature
begins to decrease.
• When the chip temperature falls to 155°C, the TSD circuit is
deactivated and the output drivers start to operate normally.

3. Notice
• If REF(pin23) is lower than 0.7V, BTL output is off.
• Under voltage protecton function. ( If SVcc is lower than 3.8V, Chip is disable. Hysterisis is 0.2V)
• Mute on BTL output voltage is as followed:
- Mute on BTL output(CH2,3,4,5) = VM / 2
- Mute on BTL output CH1 = ((PVcc2-0.6) / 2
• Each output to output and output to GND short should be kept away.
