Hi,
We got a question about bq29412DCT package marking.
About the attached bq29412DCT package photo,
The marking that represent Pin1 position is quite different from the package schematic in D/S page1.
As for the above,
Is the pin number in attached bq29412DCT…
Part Number: BQ20Z90 Other Parts Discussed in Thread: BQ29330 , , BQ29412 Hi,
I am using bq20z90 as gas guage, bq29330 as AFE and bq29412 as Over voltage protection for 4S Li-Ion Battery pack. aFTER PROPER HARDWARE AND SOFTWARE connection the device is…
The sch is proprietary. I am working with the owner to see what I am allowed to release.
but I can tell you that the SCH on page 20 of the datasheet was used and is about 90% the same. There is no BQ29412. the LEDs are replaced with a 5 segment LCD and…
Part Number: BQ20Z95
Dear all,
Lithium battery protection board made of bq20z95 and bq29412, Fuse is blown. Now, the fuse has been restored. But some of the parameters are wrong. For example, the design voltage is changed from 11.1V to 64V, and the measurement…
Part Number: BQ3060 Other Parts Discussed in Thread: BQ29412 , , BQ24172 , GPCCEDV Hi,
Now we designed a 3S Li-PO products using BQ24172 + BQ3060 + BQ29412, there is BQ3060 batch problem that the remaining power (RM register) will be locked with full charge…
Thanks Swami,
Can you get us further details on the Cell voltage sense input stages for the BQ20z90 and BQ29412?
The datasheet does not mention much, we are looking for possible stray current paths if the thermal fuse opens.
If you could provide a detailed…
Hi Swami,
Yes I am currently using the BQ29412 and the same circuit provided by TI in the technical documentation. The 4S Protector & Gas Gauge, Ultralife.
So if that is the case what would you suggest me to look into and investigate to narrow…
Hello,
I am wondering if these Chemical Fuses are a mandatory element of Lithium-ion battery packs. I am working with a Chinese Li-ion pack supplier, and they produced a pack design based on a bq20z45-R1 fuel gauge IC, but there was no Chemical Fuse circuit…
Other Parts Discussed in Thread: BQ30Z554-R1 , BQ29412 , BQ29410 Hi
I have question about bq30z554-R1 datasheet. 1) What is bq29412? Is bq29412 4-cell version of bq29512? 2)What is this parts?
Regards, PAN-M
Maybe our nomenclature is different, but I'm referring to the undervoltage protection triggered by the gas gauge's SAFE pin, and the overvoltage protection provided by a bq29412DCT. Either output turns on a FET that will "blow" the chemical fuse.…
