3.2 Over-Temperature Detection

The TAS2505-Q1 has an over-temperature protection feature for the speaker driver. The over-temperature protection feature is intended to protect the device and ensure reliable operation, and is always enabled. If the device exceeds the set temperature limit, then the output stops switching and an error flag is set as a read-only bit on page 0, register 45, bit D7.
