Hi
I have the same query like the following post.
The customer test the blink frequency 13.9HZ,
I want to know what's the C_VBAT charging and discharging?
Waiting for your reply.
Thanks

Hello Star,
The most common reason STAT blinks is when there is no battery present and the charger cycles between the re-charge threshold because of the pin capacitance. Do they have the battery connected? Are there any faults being reported?
STAT will also blink when a fault occurs but it will happen at a fixed frequency of 1Hz.

Hi Wyatt Keller
Thanks for your reply, the test waveform is disconnect the battery and enable CE pin, then the STAT blink frequency is 13.9HZ.
Does it normal?
Thanks

Hello Star,
If you enable charge with the battery disconnected the charge will oscillate between the charge voltage and the charge voltage - recharge threshold. This will cause the STAT pin to blink depending on the capacitance on VBAT.
Make sure to disable charge if the battery is disconnected.
