TAS2563: power up and power down sequence

Will Wang47

Part Number: TAS2563

Hi team,

Customer is using TAS2563 in their project, Now IOVDD and VDD are all 1.8V, VBAT is 5V. They want to know is there any specific power up and power down sequence requirement of power rail? Could you help give some comments?

Thanks and Best Regards,

Will

Hi, Will,

Unless external PVDD supply is being used, there's no specific order for the power sequencing as stated in section 11.2 of the datasheet:

Please let me know if you have additional questions or comments.

Best regards,
