Application Information
1.
MUTE,REF & SW45 Function
2. TSD Function
When the chip temperature reaches to 167
C by abnormal condition,
the TSD circuit is activated
During TSD Function is activated, OP-AMP Output (pin 6) remains
below 0.5V. (TSD monitoring function).
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 63
C, the TSD circuit is
deactivated and the output drivers start to operate normally.
3. Notice
If REF1(pin1) or REF2(pin25) 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 (CH1,2) = (PVcc1 ) / 2
- Mute ON BTL Output (CH3,4) = ((PVcc2-0.6) / 2
Each output to output and output to GND short should be kept away.
