Part Number: BQ24617
Other Parts Discussed in Thread: BQ24650, BQ24630, BQ24640, BQ24610, BQ24620, BQ24616,

Do those TI's battery charger ICs ( bq24610, bq24616,bq24617, bq24620,bq24630, bq24640,bq24650) can reach 20A charging current? If no, which one can have 20A charging current?

Hi Jack,

What is your battery charge voltage?

As for BQ246xx, it is charger controller and uses external MOSFET solution. So I think well select MOSFET then you can drive 20A charging current.

Thank you and Regards

Do you have a reference design to support your 20A charging current?

The battery charge voltage will be either 48V or 24V. The battery we want to make either 48V or 24V with 50A to 100A

Jack,
Currently I don't have ref. design on hand. You can share your schematic to me then I can help to double check.
Thanks

Jack,
We are sorry that currently our charger only support 4cell Li-Ion battery.
Thanks

What kind of battery does your reference design support for 20A Charging current?

Could you provide any reference circuit to support your 20A charging ICs for any battery?
