Sure,I am in Asia,but local support people are sales.They don't understand the theory of the Gas Gauge. So,I must to ask help in the forums.
I don't understand why the resistance of battery not update during discharging?
The application note tell…
Other Parts Discussed in Thread: BQ30Z55 Hi Friend,
I met a issue is bq30z55 V0.36 Ra table not update after did full learning, but the RU and Gauge function are enable, follow is the GG file, could you please help to command what the problem is? Whether…
Other Parts Discussed in Thread: BQ27510 I have written the firmware to program the BQ27510 from the three page flow chart from Going to Production with the bq2750x. However, every time I read register 0x66 to see if the data=0x00 I get the data to equal…
Other Parts Discussed in Thread: BQ27510 Hi,
In my board all the boards (actually four of them) .... BQ27510 pin REG25 provides an output of 3V instead of 2.5V at the REG25 pin as mentioned in datasheet.....initially i came to the conclusion that this…

I found the other post about this but still have questions. I am not using a thermistor and the datasheet doesn't do a good job of explaining the internal circuitry.
My circuit is powered from the battery only. From the reference schematic, can I drop…
Other Parts Discussed in Thread: BQ27510 , BQ27510-G2 Hi,
I have a bq27510 EVM and an MSP430 microcontroller connected via I2C. I have succesfully communicated to the gauge and have read values such as control status, flags, temperature, voltage…
Are there any bash scripts that one could use to program the bq27520-G4 chips in "production" units. If we decide to change the batteries in middle of production run what is the best way I can program calibration data for the new battery.
I wouldn't…
Hi,
A collegue of me used the same set up before and it worked (the same bq27510-G2, EV2300 and bqEVSW) so the schematic is correct.
The thing is that when I open the bqEVSW even if I select 1.22 or 1.23 an screen is shown with the following error…
