Part Number: BQ25620

BQ25620 Using this part in one of the product. need your help on configuration.

In my design , using 2 batteries with each 1cell configuration(1S1P) , and this batteries are going to connect in parallel combination.

So, Can i use above BQ25620 for battery charge management ?

Hi,

It is ok to use single-cell charger to charge two identical 1S batteries in parallel as long as both batteries have external or built-in battery protection.

Thanks,

Ning.

Hi Shubham,

We do not have a reference design available specifically for charging parallel cells. As Ning mentioned the BQ25620 can be used as it normally would with both 1S batteries connected to the BAT pin.

The BQ25620 datasheet provides a typical application figure on page 65. The BQ25620EVM User's Guide located on TI.com can also be used as a reference point for your design.

Best Regards,

Garrett
