The TAS576xM contains a complete set of protection circuits carefully designed to make system design efficient as well as to protect the device against any kind of permanent failures due to short circuits, overload, over temperature, and under-voltage. If an error is detected, the FAULT pin signals according to Table 1.
|Over Current||Output short or short to PVCC or GND||Low||Output high impedance||Self-clearing|
|Over Temperature||TJ > 150°C||Low||Output high impedance||Self-clearing|
|Too High DC offset||DC output voltage||Low||Output high impedance||Self-clearing|
|Under Voltage on PVCC||PVCC < 4.5 V||High||Output high impedance||Self-clearing|
|Over voltage on PVCC||PVCC > 27 V||High||Output high impedance||Self-clearing|
