Other Parts Discussed in Thread: BQ77910A , BQ78350 Hi Sir,
We would like to use the bq77910A for ebike battery pack application (24V/36V) and we checked it spec there was not a over charging current protection in it. Can you suggest us how to add the function…
Other Parts Discussed in Thread: BQ77910A , BQ34Z100 Dear TI support, I will use the BQ77910A with BQ34Z100 to do the balancing for a battery 4s 4400mAh and I would like to know if there is a limit of current balancing with the FET configuration that you…
Hi Alex,
I am facing the same problem. I am using a NI 8451 USB to attempt to communicate with the BQ77910A. I have done the same things you mentioned and on my Labview VI I get an error stating it does not receive an acknowledge from the slave board…

We have been doing a lot of testing on the cell balancing function of the BQ77910A. I find that during most of the charge, since we are using LiFePO4 cell the variation from the highest cell to the lowest cell…
Hi,
Would like to understand the potential root cause for the voltage leakage. There is no known loading effect and there is no short found as well. On top of that, the cell balancing feature is also not being enabled and test has been conducted with 2 new…
Other Parts Discussed in Thread: BQ77910A Hi Sir,
I am designing a battery management system. I am planting to use bq77910A as a sub module controller. A simple micro-controller will be used to monitor the state of bq77910A. When I am study the datasheet…
Hi Jonathon
I am having the same issue with cell no 1 leakage. Several batteries with the same symptom.
Did you ever get to the cause of the problem?
Thanks

Other Parts Discussed in Thread: BQ77910A Hi everybody, I'm working on a protection design for Li-ion Titanate cells using a BQ77910A. I have some difficulties to understand which design to use for the charger detection. I know the "latched2wire" design…
if UV_REC_DLY = 0 and the voltage is under UVT (without Hysteresis ) the DSG is SHUTDOWN or not after the UVD?
Because there would be no u ndervoltage detection when UV_REC_DLY = 0.
There is no detail info. in the Datasheet S. 11-12
Other Parts Discussed in Thread: BQ77910A hello!
I am an engineer for batterypack. I want to add a switch for turning on/off the bq77910a power.
I want to turn off the power of battery pack when not use, to save the energy of battery pack.
Is it possible…
