From the files menu load the configuration file:

• TAS5631PHD2EVM Configuration (1.00).cfg

The file is located in the EVM folder on the TI website. This file contains all settings for a default setup of

the EVM.

For easy access to the file, it is recommended that the user copy the files into the directory where the GUI

is installed. The default is C:\Program Files\Texas Instruments Inc\TAS5518\

For more advanced use of the GUI, see the GUI User’s Guide and data manual for TAS5518.

3 Protection

This section describes the short-circuit protection and fault reporting circuitry of the TAS5631 device.

3.1 Short Circuit Protection and Fault Reporting Circuitry

The TAS5631 is a self-protecting device that provides fault reporting (including high-temperature

protection and short circuit protection). TAS5631 is configured in back-end auto-recovery mode, and

resets automatically after all errors (M1, M2 and M3 is set low), see the data sheet (sles221) 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 TAS5631 indicate fault conditions. see the TAS5631 data sheet for a

description of these pins.
