Hello to everyone!

Is it possible to BQ76920 using without MCU, or with once programming before first start?

Need to balance and over/under voltage protection without mcu.

regards, Andrey

Hi, Andrey, AFAIK it isn't possible, because the device is AFE and it needs a controller to set registers (it has no EEPROM), to turn on FETs and to recover from faults.
