BQ79758-Q1: BQ79758

Part Number: BQ79758-Q1
Hello!
Regarding the VCELL_ACT_SUM_HI register on the BQ79758 chip:

  1. Do I need any special configuration to read this register, or can I directly read it after normal ADC configuration?
  2. Are any hardware modifications required?
  3. The final voltage value of the battery cells is multiplied by 0.0001. Is the same multiplier (0.0001) applicable to VCELL_ACT_SUM_HI?

Thank you!

    I am in the process of receiving access to additional secure resources for BQ79758 device that would allow me to dig deeper into some of the details about the VCELL_ACT_SUM_HI MID and LO registers.

    I will get back to you in the near future with this information.

    Thank you for the wait, I was waiting for access to secure resources related. Thank you for your patience. 

    1. No special configuration is required to read this register, it is similar to reading an individual cell's HI/LO voltage. 

    2. No hardware modifications are required

    3. Can you point to where you are seeing this 0.0001 scaling? I can then clearly define if the same multiplier is applied. 

    Thank you!
