BQ25713EVM-017: Volatile/non-volatile memory

Part Number: BQ25713EVM-017

Hello.

I am not using the USB adapter to configure the board. I am writing the registers directly over I2C. This is working great except that every time the device loses power, the registers always reset back to defaults. Is there a way to access the registers in a non volatile way?? Our device will be out in the field and could possibly lose power due to conditions beyond our control. I am trying to find a solution where I don't have to reprogram the registers each time the device gains power again. That is an inconvenience that I would rather avoid if possible.

Thanks for your support.

  • Hey Jacob,

    Unfortunately, when this device POR's, the registers will lose their settings. 

    While the charging current will have to be programmed each time, keep in mind that the CELL_BATPRESZ pin sets the default battery charging voltage and the default minimum system voltage.

    Regards,
