Hi
I have a query need your help.
During the test, everything worked normally. When charging the battery, the STAT LED light started to blink.
The REGN voltage was 5.2V, the power supply voltage was 5V, the battery voltage (2 cells) was 7.4V, and the SYS voltage was 6.4 when the battery was disconnected. The circuit should be fine and it worked normally before.
Leave the CE pin floating, power on, then pull it low, and power on again. The circuit can charge normally, but after power off and power on again, it becomes unable to charge.
How to solve this issue.
Thanks
