Part Number: BQ294502 Hello,
We're working with the BQ294502 and have a question on the input filter.
The minimum recommended capacitor value is 0.1uF. Is this due to an RC time constant with the resistor?
Wondering if we could lower the cap value…
Part Number: TPS7B81-Q1 Other Parts Discussed in Thread: BQ294502 , Used by TPS7B81-Q1, BQ294502, etc. I can get the data from the part datasheets but the general package drawing for DRV 6 doesn't have them.

But it also tell us there is a possiblity that the bq294502 could blow the fuse.
Is there a possiblity that some cell connection sequence could cause bq28z610 Voltage(0x08) ,cell1 voltage, cell2 voltage,B attery voltage abd Pack voltage to be not stable…
Part Number: BQ294502 Other Parts Discussed in Thread: BQ77905 Hi, Team,
My customer want to use BQ294502 to do the 2~3Cell battery protection. Need to pass the UL2595, do we have some suggestion for this? How about the reference design or just use the…

Dear Sir,
Here I am using a battery protection ic of bq294502 for 3s2p
the battery pack vout 9V~12.6V. each cell around 4.2V.
So far I found the OUT keeps high 2.49v and after checking the Vc1/Vc2/Vc3 , the voltage is 3.5938V/3.6v…

Hi,
The datasheet state that the Icc(max) is 1.25uA at (V3–V2) = (V2–V1) = (V1–VSS) = 2.8 V with TA =–40°C to 60°C. Then do you have any reference information of Icc with room temperature? Our customer hope to know it just for their information.…
Thank you.
I would have another 2 question:
When is a secondary cell voltage monitor (e.g. bq294502) necessary in addition to bq4050 and bq25703a? Is there any further reading available on this topic?
It seems like bq28z610 would be a suitable replacement…
Hi Marc,
The BQ77915 is only equipped for 3-5S battery packs. We do have some 2S protectors, but they do not include all of the features of the BQ77915. Here are some of our datasheets for 2S protectors:
