3 Protection

This section describes the short-circuit protection and fault reporting circuitry of the TAS5614 and

TAS5612 devices.

3.1 Short Circuit Protection and Fault Reporting Circuitry

The TAS5612 and TAS5614 is self-protecting devices that provides fault reporting (including

high-temperature protection and short circuit protection). TAS5612 and TAS5614 is configured in back-end

auto-recovery mode, and resets automatically after all errors (M1, M2 and M3 is set low), see the data

sheets (TAS5612 (SLAS682) or TAS5614 (SLAS680)) for further explanation. The device will re-start itself

after an error occasion, and report through the SD error signal.

3.2 Fault Reporting

The OTW and SD outputs from TAS5612/14 indicate fault conditions. see the TAS5612/14 data sheet for

a description of these pins.
