Hello Wang,
We do have multiple offerings that may suit your application. Couple more questions that can help narrow down the options:
What is your charging current?
Are the cells removable or are they embedded in the system?

Other Parts Discussed in Thread: MSP430G2212 , BQ27510-G2 , BQ27410-G1 hi,
I am interfacing MSP430g2212 controller with bq27510-G2 fuel gauge through USI-i2c master mode. I have taken an example code from "http://processors.wiki.ti.com/index.php/I2C_Communication_with_USI_Module…
Stefani,
yes it worked this way. The G1 version of the bq27510 did'nt support such a big battery. So I made belive to the fuelgauge that the capacity is 1/3 of the actual battery (6.3Ah) and the resistor is a 30mOhm. In reality its a 18.9Ah LiPolymer…
Hi Fabien,
Now that you mentioned it, is there a particular reason you are using a single-cell gauge like the bq27510-G3 in a multi-cell configuration? It's not necessarily a bad thing to do this, but TI has a new gauge, the bq34z100-G1, that is explicitly…

I am using the BQ27441-G1A with a 18650 Li-Ion cell (3400mAh, 3.7V) and a BQ24250 charger. Unfortunately, the SOC value jumps down most…
Other Parts Discussed in Thread: BQEVSW , BQ27520-G4 My company is considering the use of the BQ27510-G3 Fuel gauge, and we bought the BQ27520EVM to evaluate the part.
We received the EVM with BQ27520-G1 firmware, so I tried to update the firmware to…
Hi Jared,
Thank you very much for your reply. The '620 looks interesting - does it use the same learning cycle and manufacturing steps as the 27500? i.e. software tool to find the data tables for the models? Calibration during manufacture? Anything…
