Other Parts Discussed in Thread: BQ25798, BQ24610

We are looking for LiOn battery charger:

24VDC @40A DC

We used BQ25798, but BQ25798 is not enough for us any more

Thank you

Hi Ramin,

The closest fit from TI is the standalone (no I2C) charger controller, BQ24610 with added HDRV and LDRV gate driver ICs and at least 2 high side and low side FETs in parallel.

Regards,

Jeff

is it possible to place these charges in parallel to amplify the current?

Hi Ramin,

Yes. In theory, paralleling 4 of the 10A capable (without extra gate drive circuit) BQ24610 is possible but we have not tested this configuration. If you try it, make sure that only one of the chargers is used for termination, i.e. set the other chargers to terminate earlier.

Regards,

Jeff

Thank you. Next step is to order the evaluation board for BQ24610 series.
