Other Parts Discussed in Thread: BQ24040, , BQ24074
Hi, team,
The following is described on page 12 of the data sheet. I have some questions about this description. Please tell me about them.
=== Description on Datasheet_Page-12 =================================================================
Normal CC / CV Mode
--------
Once the "input current "falls below the termination threshold (ITERM), BGATE is turned off and CHG goes high impedance. The system output is regulated to 4.2V and the battery is disconnected from OUT, however supplement mode is still available.
================================================================================================
Q1: Does "INPUT CURRENT" in this description mean the VIN terminal current (IIN)?
If the answer to Q1 is yes, then
Q2: Normally, the charge IC judges the charge stop when the charge current of the battery falls below ITERM.
However, In case the IC determines that charging is complete when “Input Current” falls below “ITERM”,
If the load current on the system side is more than ITERM, I think that the IC can not judge that charging is complete even if the battery is fully charged.
What do you think about that?
Moreover, since this product also has no charge timer function, it can not stop charging.
Best regards,
H.Someno
