Hi,
One of my customer is doing EPOS design based on TI's reference design in web. They have removed 7.4V battery and added 3.7 battery in the design. Kindly help to review the schematics for BQ27540 used in the design and please confirm whether the attached circuit will work for hours backup. Kindly need your help. I attached the shcematics as well as excel in which voltage and current consumption of each and every device is mentioned. 0284.POWER POS 13.pdf8623.POS-PWR-ANALYSIS-22-07-2014.xls
