Application Information

1. Reference Input & Stand-by Function

• Reference input (PIN 27)

• Stand-by input (PIN 28)

The following input conditions must be satisfied for the normal stand-by function.

2. Protection Function

Thermal shutdown (TSD)

If the chip temperature rises above 175

°C, the thermal shutdown (TSD) circuit is activated and the output circuit is in the mute

state, that is off state. The TSD circuit has a temperature hysteresis of 25

°C

3. Separation Of Power Supply

Stand-by input voltage

Below 0.5V or OPEN

Stand-by function is activated so the bias block and the

power block are disabled

Stand-by input voltage

Above 2.0V

Normal operation
