BQ25895: Import initial setting while power on except I2C

Peter Tseng

Part Number: BQ25895

Hi Team,

Customer wants to check if the device battery is totaly discharged then plug the power supply but MCU is not wakeup,

the BQ25895 will load default setting!

Is there any way to keep the customer setting or load from external EEPROM while power on and without I2C ?

Thanks.

Hi,

Is valid VBUS connected when the battery is totally discharged?

Thanks,

Hi Sir,

Once the battery was totally discharged, there is no valid power on VBUS unless we plug in power supply to device.

Hi,

In this case, the IC has lost power, then the IC can't memorize custom register settings.

Thanks,

Ning
