Class-D amplifier faults
Table 1. Amplifier Fault Table
FAULT 0
FAULT 1
DESCRIPTION
1
No fault—The device is operating normally.
1
0
Charge pump under-voltage lock-out (VCP-UV) fault—All low-side transistors are turned on, shorting the load to
ground. Once the charge pump voltage is restored, normal operation resumes, but FAULT1 is still active. FAULT1 is
cleared by cycling MUTE, SHUTDOWN, or the power supply.
0
Thermal fault—All the low-side transistors are turned on, shorting the load to ground. Once the junction temperature
drops 20
°C, normal operation resumes. But the FAULTx terminals are still set and are cleared by cycling MUTE,
SHUTDOWN, or the power supply.
These logic levels assume a pull up to PVDD from the open-drain outputs.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
