8.4.6 Thermal Foldback

The TAS2110 monitors the die temperature and can automatically limit the audio signal when the die temperature reaches a set threshold. It is recommended to use PurePath™ Console 3 Software to configure the thermal foldback as the software will perform the necessary math for each register.

Thermal foldback can be disabled using TF_EN. If the die temperature reaches TF_TEMP_TH this feature will begin to attenuate the audio signal to prevent the device from shutting down due to over-temperature. It will attenuate the audio signal by TF_LIMS db per degree of temperature over TF_TEMP_TH. The thermal foldback with attack at a fixed rate of 0.25 dB per sample. A maximum attenuation of TF_MAX_ATTN can be specified. However if the device continue to heat up eventually the device over-temperature will be triggered. The attenuation will be held for TF_HOLD_CNT samples before the attenuation will begin releasing.
