Part Number: EV2400 Other Parts Discussed in Thread: BQ26231 , BQEVSW I am working with a battery pack using the TI BQ26231 fuel gauge in HDQ mode. The interface hardware is an EV2400, and the target OS is Windows XP (32-bit).
I understand that the…
Part Number: BQ26231 Other Parts Discussed in Thread: BQ35100 Hi, I am looking for recommendations on a coulomb counter for a product that sleeps at the 10uA range and wakes up to possible 400mA range. The product uses non rechargeable Li/FeS2 battery…
Other Parts Discussed in Thread: BQ26231 Hi,
I wanted to bring it to your attention that SR1 & SR2 have different pinout locations on Page 1, 2 & 6 of the datasheet for the bq26231.
I also want to make sure that the correct pinout is the one reflected…
Other Parts Discussed in Thread: BQ26231 Hi.
I have question for ba26200 and bq26231 for Shunt Resiter setting.
Now we thinking this Shunt Resister 0.02 ohm change to 4m ohm or under 2m ohm.
Can possible change about this shunt resister vale…
Hello Afzal,
I don't think there is a suitable gauge for single cell NiMH. BQ26231 assumes cell voltage = supply voltage. You will need to scale the voltage to a higher value rather than just boosting for power supply.
Hi Julian,
May I ask why you chose bq26231? If you just need a basic coulomb counter (not a complete fuel gauge solution) then I would recommend using a bqJunior (bq27000/bq27200/bq27010/bq27210) and using the coulomb counting registers per the example…
If you just want a coulomb counter, then the bq26231 may work. We also have a few CEDV type gauges that just use coulomb counters. The bq27200 and bq2083 can be configured for multi-cell.
Hello Jason,
I am designing a new UPS with external batteries, and I'd like to keep track of their SOC. Some of those batteries (LiFePO4, LiCoO2) will have a BMS with integrated bq40z50 (IT + NFET HiSide control + Led display) or bq3060 (CEDV + NFET…
Other Parts Discussed in Thread: BQ2060A , BQ26500 , BQ26501 Hello Everybody,
I am designing a new DC-UPS with external batteries, and I'd like to keep track of their SOC. Some of those batteries (LiFePO4, LiCoO2) will have a BMS with integrated bq40z50…
Other Parts Discussed in Thread: BQ26231 , BQ26220 , BQ2023 , BQ26200 Which device would TI recommend to use in a large LiFePO4 pack for charge monitoring only?
Say everything else is taken care of (safety, balancing etc), but one needs to do low side…
