2. Thermal Shutdown
• The VREF BG is the output voltage of the band-gap-referenced biasing circuit and acts as the input
voltage of the TSD circuit. The base-emitter voltage of the TR, Q11 is designed to turn-on at below
voltage.
VBE = VREF BG × R12 / (R11+R12) = 460mV
• When the chip temperature rises up to 175°C, then the turn-on voltage of the Q11 would drop down
to 460mV.(Hysteresis: 25℃), the Q11 would turn on so the output circuit will be muted.

•The voltage, VREF, is the reference voltage given by the bias voltage of the pin 23. It can be reduced
the total gain of BTL drive part, use additional series resistor into the input pin (pin3,10,19,25). It can
also increase or decrease the voltage gain of the CH1,CH4 using adjustable pin (pin4,9,20,2424) by
inserting an external series resistor.

5. If the bias pin (23pin) drops below 1.4V, the output current is muted. Make
sure that under normal operating conditions, this pin is at 1.6V or above.
6. If the power supply voltage drops below 4.5V typ., the drivers are turned OFF.
When the voltage exceeds 4.7V typ., the drivers return to their previous state.
