BQ24195: BQ24195 charging mode CC and CV mode is not following charging current and set regulated charge voltage limit

Part Number: BQ24195
Other Parts Discussed in Thread: BQ78Z100, BQ34110

Hi,

As per the datasheet of BQ24195 I should see the below for charging and discharging voltage/current for different modes such as CC mode and CV mode. I can see that in the graph mentioned in datasheet the battery voltage is constant once it reached set regulated voltage and current also starts decreasing. But in my case I am getting different results. I have set the charging voltage 'reg 04' as 4.112V. Input current and voltage limit as 3A and 4.68V respe in 'reg 00'. Set fast charge current limit is 1792mA in 'reg 02'.

When I plot the graph of voltage against current looks like voltage is still keeps on increasing even though current starts ramping down. It does not follow the curve mentioned in the datasheet. i was expecting the same graph which is mentioned in datasheet. Does my expectation is correct? Or the curve that I got from my experiment is correct? If not, then what may be the reason for this? Please comment.
