Other Parts Discussed in Thread: EV2400, BQSTUDIO,
Hi Team,
Software, tools: bqStudio (1.3.104 Build 1) + EV2400
BQ27426 is connected to the battery to be tested, and EV2400 is connected to the I2C interface of the 27426 device.
Set the parameters of BQ27426 in the software bqStudio, configure the chemical ID1202 matching the battery (4.2V), and lock the BQ27426 device with SEALED.
After completing the above steps, remove EV2400 from the set BQ27426 and set up other BQ27426 to be tested. During this period, the set fuel gauge is in an idle state with battery.
When EV2400 was used again to connect the set BQ27426 to confirm the setting status, it was found that the set parameters of some devices were reset and restored to the device default parameters.
Because the battery connected to the device is not removed during the idle period, a power-down reset is unlikely. Could you help analyze what other possibilities may cause BQ27426 to be reset by parameters when the power is not turned off after setting parameters?
Regards,
Annie
