UCD90160A: Any concern if we apply AMON first before UCD90160A power up?

Part Number: UCD90160A

Tool/software:

Hi TI team,

Just wonder any concern if we supply AMON first before UCD90160A is power up?

As i understand, the UCD90xxx device has an internal ESD diode to protect on all IO pins and MON pins. When the UCD90xxx device is not powered by a 3.3-V supply, if a positive voltage is applied to a pin, the ESD diode is forward biased and a leakage current may be observed. 

However, any other concern we should aware?

Thanks.
