Other Parts Discussed in Thread: AM3352

Hi,

One of my customer is doing EPOS based on TI's design. They have taken out the 7.4V battery and added the 3.7V instead and designed the attached circuit. Kindly help to review the schematics for PMIC.Can we use this PMIC for powering AM3352? Need your help.

please find the attached files for schematics as well as voltage and current of each and every device in the design.

Aravind,

VIO should be tied to LDO1

Pull-Up resistors need to be to the supply that is used for VDDSHV6, with the exception of nWakeup which should be tied to LDO1

You have a switch placed between the SYS pins and inputs to the converters. Please be aware that the VINX pins are required to be within 300mV of the SYS pin voltage.
