BQ24297: Power on reset

S.Satoshi

Part Number: BQ24297

Hi,

I understand that VBUS or VBAT need to decrease below than each UVLO threshold to hardware reset. Then how long time it should keep blow than ULVO threshold to reset all the registers?

Hey Satoshi-san,

The register reset should be relatively instantaneous compared to any communication speed. Essentially, below these voltages, the charger loses all power; not just registers resetting. The UVLO thresholds essentially yield a POR event.
