Hi,

Could you tell me CHG pin status in recharge.
I think that it is the operation of the recharge.

However,Data sheet has not been described CHG status in recharge.

/CHG will stay high in pre-charge.
Re-charge will only happen when VOUT drops below 4.1V which is the re-charge threshold.

Thanks,
Wenjia

Hi Wenjia-san,

Please let me reconfirm this to make sure.
There is following description in Data Sheet

It is recharged when this threshold,.
And, the status of the CHG terminal is Hi-Z.
Is my understanding of this correct?

Yes once the VOUT drops to re-charge threshold, the charging will be resumed. However, /CHG pin will not indicate re-charging so it will not be pulled low.

Thanks,
Wenjia
