Hi,
My customer is CM for big e-meter company. they used BQ24130 for super cap and MP with a lot of this device. but recently, they found a few of new batch devices show different charging manner as below show.
as can see, the blue one customer think it's abnormal. the charging current first reach to a high level, then drop to the charging current they set, but normal one, the current ramp up from a level to their setting.
they confirmed the super cap has been discharging to zero before the test. they want to know what may be the issue. thanks.
