Hello Leonard,
We do have multiple offerings that may suit your application. Are the cells removable or are they embedded in the system?
For high accuracy gauging, Impedance Track is a good alternative. If you are planning on having removable battery…
The bq27410-G1 uses TI's Impedance Track Lite (IT-LITE) algorithm. It works pretty much the same way as their more complex gauges that use the regular Impedance Track algorithm (see SLUA450 ), just that many parameters are hardcoded (not customizable…
Part Number: BQ27421-G1 Other Parts Discussed in Thread: BQSTUDIO , BQ27426 , BQ27510 Hello,
We have designed a device which uses a bq27421-G1A. The Fuel Gauge is connected, through a protection circuit, to the battery.
We configured the fuel gauge…
Other Parts Discussed in Thread: BQ27500 , BQ27541 , BQ27541-G1 , BQ27510 How is the calibration profile affected if two single cells are connected in parallel to the battery pack instead of a single cell?

Hello Choukri,
Unfortunately, there is no documentation for using the bq27510 with bqStudio at the moment. I've attached a quick presentation I put together for another one of our gas gauges that goes over the different tabs of bqStudio. The devices…
Hi Kohei,
The SOH FCC doesn't seem to be open to customers in the bq27510-g3. In some other devices, it is possible to read this value via i2c or smbus.
I would suggest you set the SOH LoadI to a typical current of the application.

Hi Bayram,
Please refer to the I2C app note for this device found here: www.ti.com/.../slua467b.pdf
The summary is extremely helpful:
1. Handshaking between the host and gauge is performed by five bit sequences: START, REPEAT START, ACKNOWLEDGE…
Hi Vojin,
pls reference the technical reference manual of this device.chapter 4 discusses how to write and read from the gauge. I have attached additional material you might fine useful
the link below contains the flow on doing calibration using your…
