Part Number: BQ27425-G1 Other Parts Discussed in Thread: BQ27425-G1 , BQSTUDIO Hello battery gas gauge team,
We have a customer seeing voltage and current values that are completely out of range when reading on I2C. I know the bq27425-G1 is NRND, so…
Other Parts Discussed in Thread: BQ27425-G1 Is there any documentation outlining how to "fanout" the BQ27425-G1?
Looking at the evaluation module documentation it looks like they put a via right in the pad itself.
Can anyone confirm this or point…
Other Parts Discussed in Thread: BQ27425-G1 Is it possible to use bq27425-G1 with 2-series cells?
If it is possible, is resistor divider used or is only bottom cell monitored?
Other Parts Discussed in Thread: BQ27425-G1 If I set the Chip Enable (CE) Low on the BQ27425-G1, will the rest of the device function? Does this just disable the LDO? Does it put the whole device into power saving mode?
Part Number: BQ27425-G2A Other Parts Discussed in Thread: BQ27425-G1 Tool/software: Hello!
Situation: BQ27425-G2A on over 100 custom PCBAs. The DEVICE_TYPE read is 0x0245 which is what to be expected. But the FW_VERSION reported by the gauge is 0x0202…

I'm testing bq27425-G1 fuel gauge. From the beginning it is displaying wrong pack voltage in GUI. I'm trying to understand what could be reason for this but not found till now.
I previously evaluated…

Hello Dominik,
Thank you for your reply.
You mean BQ27425-G1/2A/2B support different type of battery pack (e.g. LoCoO2, LiMn2O4). Is it correct?
Also, thank you for sharing latest single cell IT gauge.
I understand this has same algorithm…
I tested this on the EVM today - the bq27425 will remember the sealed state (it has non volatile memory for some data classes but not all). My previous answer was not correct. You will have to always unseal the bq27425 after a POR if you sealed it once…
Why did you set OpConfig to 0x5EFE? RSVD0 must be 0 and RSVD1 must be 1 for proper operation. If you have and external pull-up on BIN then you can set BI_PU_EN to 0. See Table 8 in www.ti.com/.../bq27425-g1.pdf .
Please change this to 0x09FE
