BQ24640: Supercapacitor charge current, at Nonsynchronous mode (0V-2V)

Pedro Ferreira

Part Number: BQ24640

Tool/software:

I'm trying to use the bq24640 to charge a 24V supercapacitor bank with constant current of 10A

I'd like to know what is the charge current that bq24640 could supply, when the supercapacitor is completed discharged (0V) until it gets 2V.

I suppose the bq24640 is on non synchronous mode, but I don't know how this mode charge the supercapacitor until it gets 2V.

Kind Regards

it will be the same as the fastcharge current of 10A. I confirmed on the BQ24640 EVM.
