Hello, I would like to ask, when I banned the charging time and pre-charging and termination, what was the charge full of signals?

Hello,

I do not understand your question. Are you disabling the safety timer, pre-charge, and termination thresholds?

What do you mean "charge full of signals? Are you asking about the STAT1 and STAT2 pins?

Hello, I would like to ask, when I connect the TTC pin low, prohibit charging time and termination mode, then the battery indicator signal will always show charging, then when I lower the TCC, which part of the charging signal can be seen?

Hello,

I understand the first part of your question. But what do you mean by the following? If TTC is already pulled low, how much lower will you try to go below GND?

dear joel.

How do I know the battery is full when I pull the TTC down?

Hello,

When TTC is pulled down, the charger will not terminate. Typically you would use a battery fuel gauge to tell if the battery State of Charge (SoC) was near 100%. A charger by itself will not tell you if you are near 100%. It will only cut of charge current according to the battery manufacturers spec.

Because you disable termination, the charger will remain in charge mode. There will be no change in STAT pins unless there is another fault.
