Part Number: BQ76907 Tool/software: Hi Team,
How to calculate the current offset for BQ76907.
Method 1: -5A and -2A Current measurement
Current 1 = -5000mA
Raw Current 1 = -83940 (average of 30 reading)
Current 2 = -2000mA
Raw Current 2 = -30179

Part Number: BQ76907 Tool/software: Hi TI support team,
I would like to seek your advice on how to calculate the maximum and minimum current range using a 300 μΩ Rsense.
Current = [(24bit ADC – Current offset) x current gain]/8192 …

Hi Jacob,
Let's take the first row of the table as an example.
Rsense, Max Current, and Max Voltage are all a function of each other (V = IR). These you pick two for your system and calculate the remaining variable.
Min LSB Allowed is just the Max…

My system always trigger a UVP protection where all cell voltage is correct. Alarm Status, 0x62 = 0x8000 Safety status A = 0x40
In my system, Vcell mode, 0x901C = 0x05 (cell1, cell2, cell3, cell5…

Dear TI support team,
1.Do you have any documents, advice, or examples on how to calculate the cell under-voltage and over-voltage protection delay?" 2.How can I calculate the ADCSCAN interval for 3 seconds (5…
Part Number: BQ76907 Tool/software: Hello I am considering connecting the BQ76907 to a LiFePO4 battery module (12.8Vx2, 20000mAH). Looking at the datasheet, it seems that the maximum measured voltage between each VC is about 5.5V. In this case, is it possible…
Part Number: BQ76907 Tool/software: Hello.
I think the BQ76907 is a passive cell balancer, but is there a way or example to change it to an active cell balancer? The batteries I plan to use are two LiFePO4 (12.8V) 20000mA batteries in series.
I think…
