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 pin19,20,21 is high, the TR Q1 is turned on and Q2 is off, so the bias circuit is enabled. On the other hand, when
the pin19,20,21 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;
