ZHCSF47E June 2016 – December 2017 TAS2560
PRODUCTION DATA.
The TAS2560 device has an integrated undervoltage protection on the analog power supply lines VDD and VBAT. The undervoltage limit fault is triggered when VDD is less than 1.5V or VBAT is less than 2.4 V. Once the fault is detected the TAS2560 device will disable the audio channel and power down the Class-D amplifier. When an under-voltage event occurs, a status flag INT_AUV is set. This register is sticky and the bit will remain high for as long as it is not read, or the device is not reset. The undervoltage event can also be used to generate an interrupt if required. Refer to IRQs and Flags for more details. To re-enable the audio channel after a fault the Class-D the device must be powered back up using field PWR_DEV, see Table 53.
