    Hi Maxwell, I have attached, the screenshot of the BQ studio software screenshot, previously I was using the BQ76920 evaluation software as AFE use. But I tried the BQ studio software as well but it shows only 3 cell voltage data but I have connected…

  • RE: BQ25120A: Unexpected switching pattern and noise on 10-15% of BQ devices

    Hi Juan. Yes we are seeing this with the EVM with 66uF or more capacitive loading and 8.2KOhm load resistor. How much capacitive load triggers the issue is BQ unit dependent. With 132uF this is pretty easy to replicate with the EVM. With less capacitance…
