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.</P><P>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?</P><P>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.</P></BODY></HTML> Thu, 21 Feb 2019 14:02:02 GMT https://community.nxp.com/t5/Layerscape/LS2088A-TA-BB-VDD-and-TA-BB-RTC/m-p/882221#M4076 sekuru_saimukhe 2019-02-21T14:02:02Z Re: LS2088A TA_BB_VDD and TA_BB_RTC https://community.nxp.com/t5/Layerscape/LS2088A-TA-BB-VDD-and-TA-BB-RTC/m-p/882222#M4077 <HTML><HEAD></HEAD><BODY><P>This 1.5mW number&nbsp; is absolute maximum rating, actual power consumption depends on temperature and may vary from batch to batch.
