I are working LS2088 based project. I have a query regarding the power consumption of TA_BB_VDD pin which is given as 1.5mW in the application note. I just want to know whether this is the peak power dissipation or the continuous power dissipation on the TA_BB_VDD.

Regarding the TA_BB_RTC, can it be connected to the TA_BB_VDD if the thrust programming is not done i.e for normal operation?

I want a rechargable battery for generating TA_BB_VDD and the lifespan of the fully charged rechargable battery should be 7 days. So kindly let me know any reference calculation is available for the battery capacity estimation.
