Part Number: BQ25619 The IC does not limit income current as programmed when connected to a dumb power supply such as a bench supply. I.e. if the bench supply is set to 1Amp and the charger IC is set to 345mA max it still allows 1Amp charging. How do…

Sorry for late reply.
I am still confused for your feedback..
Q1: Do you mean BQ25619 and BQ25619E with differential Vreg_acc? BQ25619 is more accurate than BQ25619E? A m I correct?
Q3: about your comments, "no more than 1mV" is for actual experiment…
Part Number: BQ25619 Hi
The parameters shown on the left in the picture are my initialization parameters, but after the charge is full(reg08 is 0x3c), after reading register 08 twice, several registers have changed, which is not the result I expect.On…
Part Number: BQ25619 1、在在评估板上测试，用一个4.35V的电池给BQ25619供电，插入VIN 5V，设置BQ25619 demon板，充满截止电压4.36V或者4.37V，电池充满之后有104uA的漏电流，这是正常的吗？此时SYS没有挂载，如何解决? 2、BQ25619的SYS和地短路之后，输入端VIN 5V 有接近190mA电流持续输入，电池端没有被充电，请问这个电流消耗到哪里了？
I do test on the evaluation board. 1、use 4.35V…
Part Number: BQ25619 Other Parts Discussed in Thread: TPS630250 , Dear Team,
Our customer follow the EVB schematic, but the voltage get big ripple around 500mV.
Could you guide us how to check it?
Thanks a lot!
Part Number: BQ25619 Hi Sir,
Customer tested bq25619 between Vbus and Icharge looks a little different with d/s.
Between supply Vbus to Ibat =280~290ms (same as datasheet)
but there are 2 current spike in front of battery charge current, do you have idea…
