BQ24020: POR conditions

yuji.S

Part Number: BQ24020

Hello,

I can't find out POR conditions in datasheet.

I am designing the charger that battery is connectd to bq24020 alltime.
I want know Timer fault reset if we disconnect power to Vac and Vusb after bq24020 detected Timer fault.

Could you teach me POR conditions in detail?

Best regards,

Hello Yuji,

Unfortunately I am still waiting on the EVM to arrive (we did not have any handy). I will check on this next Monday.

Thanks for your patience,

Nick

Hello Yuji,

The timer fault is reset if both Vac abd Vusb go below the UVLO threshold (2.5V).

Thanks,

Nick
