Part Number: BQ25700A

Hi,

I want to know if the system can be powered up and operated only with DC power source(without battery) when  BQ25700A is applied to the system.

When I checked DS, Power-up can be done when DC- source is pluged in. But I want to know the system can be operated only with DC-source without battery.

Regards,
Junghwa

    The system can be powered up and operated only with DC power source(without battery) if BQ25700A charger's input is available.

    "I want to know the system can be operated only with DC-source without battery." Yes. If the battery is absent, the system voltage is regulated to Vsys_min register setting voltage.
