Class-D amplifier faults
Table 1. Class-D Amplifier Fault Table
FAULT 0
FAULT 1
DESCRIPTION
1
No fault. The device is operating normally.
0
1
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. This is not
a latched fault, however. 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 (not a latched fault). But the FAULTx terminals are still set and are cleared
by cycling MUTE, SHUTDOWN, or the power supply.
headphone amplifier faults
The thermal fault remains active when the device is in head phone mode. This fault operation has exactly the
same as it does for the Class-D amplifier (see Table 1).
If HPVCC drops below approximately 4.5 V, the head phone is disabled. Once HPVCC exceeds approximately
4.5 V, the head phone amplifier is re-enabled. No fault is reported to the user.
