Protection
This section describes the short-circuit protection and fault-reporting circuitry of the TAS5611 and
TAS5613 devices.
TAS5613 devices.
3.1
Short-Circuit Protection and Fault-Reporting Circuitry
The TAS5611 and TAS5613 is self-protecting devices that provides fault reporting (including
high-temperature protection and short-circuit protection). TAS5611 and TAS5613 is configured in
back-end auto-recovery mode, and therefore; resets automatically after all errors (M1, M2, and M3 is set
low); see the data sheet (
high-temperature protection and short-circuit protection). TAS5611 and TAS5613 is configured in
back-end auto-recovery mode, and therefore; resets automatically after all errors (M1, M2, and M3 is set
low); see the data sheet (
) for further explanation. This mean that the device restart
itself after an error occasion and report through the SD error signal.
