BQ4050: BQ4050

Part Number: BQ4050

Tool/software:

HI ti team

               We used BQ4050 in our product. We conducted aging learning before shipment, and Max error will be updated to 2%. However, in order to reduce the power consumption of the product, we need BQ4050 to enter shutdown before shipment. If BQ4050 enters shutdown before shipment, Max error will increase to 100% after wake up. If BQ4050 needs shutdown before shipment, can aging learning before shipment still improve the SOC accuracy of BQ4050?What do we need to do to ensure the accuracy of the BQ4050 SOC?

  • Hello,

    Doing aging learning before entering shutdown will still be effective in the SOC accuracy of the gauge due to bq4050 being a flash gauge. The values from the aging learning will still be in memory when the gauge wakes up from shutdown.

    Regards,
