I am using the PMIC PF1550 in my design to power the I.MX6ULL micro processor. My design include the battery charging capability also. But when i am connecting a battery it is charging only upto 3V. And this charging takes a lot of time also (2 or 3 Hours). I have read the status of CHG_SNS and CHG_OPER and from that charger is ON and also by reading BATT_SNS I got the info that Vprechg.lb<Vbatt.I am attaching the SCH section of PF1550 and the datasheet of the battery I am using. Please help me resolve this issue.
