FAULT 0

FAULT 1

DESCRIPTION

1

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

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.
