Part Number: BQ24031 Hi Team,
we have been using the BQ24031RHLR for a previous project and it worked fine on many 100k units.
Now with our new design we experienced on some boards that the power manager got damaged after production. The chip consumes…
We need to look at this application of the BQ24031 a little more.
The charge current accuracy is a concern along with the termination current accuracy.
Hi Ross
The battery will require a charge voltage of 4.1V and charge current of 25mA, termination is probably 10% or 2.5mA. The accuracy of the current is not listed. The bq24031 is designed for larger batteries and scaling down to 25mA / 2.5mA will…
Part Number: BQ24031-Q1 Other Parts Discussed in Thread: BQ24031 Hello,
BQ24031 datasheet mentions that DPPM pin can be used for charging control. It however seems to affect over current recovery as well. Is it recommended to use TS input for charging…
Part Number: BQ24031-Q1 Hi,
I have a question I would like clarified on the BQ24031-Q1; given that the AC in line cannot handle more than 16V DC, my intention is to use a regulator (TPS7B8250QDGNRQ1) prior, which can handle a wide input battery voltage…
Part Number: BQ24031 Dear all,
I am using the BQ24031 in one of our designs and we have requirements that force us to keep current consumption of the product beneath a certain level.
Now while powered from battery this means 1.5mA for the whole system…
Part Number: BQ24031-Q1 Hello,
Customer have a current setting question of charging current and termination current for AC and USB input source. AC input will use on wireless power charging source.
Here is our charging current requested 250mA for…
Hi Jeff,
We are testing the BQ24031 in this setup, and have found a strange issue. If the battery voltage is above 3V, and we start charging, the part works as expected. However, if we start charging below 3V, when it transitions from below 3V to above…
Other Parts Discussed in Thread: BQ24031 Hello, Would you mind if we ask relation with BAT voltage on BQ24031. <Question> Please tell us difference of initial behavior, when BAT voltage is above 3.0V or under 3.0V. And then, is DPPM voltage relation with…
Other Parts Discussed in Thread: BQ24031 Hi All, Would you mind if we ask BQ24031? <Question> Please refer to following attached file; 2626.Attached file.pdf When the condition is the following, even though OUTPUT regulation volatage is 6.0V on the datasheet…
