BQ34Z100-G1: Charge Term Taper Current

Adrian Hallas

Part Number: BQ34Z100-G1

Hi,

The diagram below is from the document SLUA903 - Data Flash Configuration Settings Pertinent to Learning Cycle Completion

Can someone explain where on the diagram the Charge Term Taper Current would be?

Paragraph 2.4 of the document states that the Chg Current Threshold should be set lower than the Charge Term Taper Current, but I can't make sense of this.

Many thanks,

Adrian

Hello Adrian,

It is at end of charge where it approaches zero. In most applications the drop to zero will be sudden at the end. The point before zero is taper current.

Thanks for the reply Shirish. That's what I thought, but then how can the Chg Current Threshold be below this level?

Hello Adrian,

Charging is detected at all values above Charge current threshold. If the threshold was higher then charging will not be detected, which means taper condition will not be detected either.

Thanks Shirish - that makes sense. It must be a typo in the documentation.
