Reg:TAS2553 Power Sequence

Other Parts Discussed in Thread: TAS2553, TAS2505

Hi,

Currently I am Using TAS2553 in one of my project, I have quesation regarding power on sequence requirement of TAS2553.

As per the datasheet the power on sequence is VBAT-->IOVDD-->AVDD

but in my design I have implemented like 3.3V will reach VBAT and IOVDD at same time, and and then 1.8V will reach to AVDD. since  1.8V generating  from 3.3V.

unlike in datasheet in my design VBAT and IOVDD has the 3.3V at same time. can you please let us know is it ok  to have implementation in my current design? or is it mandate to follow the sequence as mention in datasheet.
