Tool/software:

if the customer only need Buck mode, whether they could left LPDRV2 and HDRV2 floating and remove Q3 and Q4?

Hello Fabio,

Thanks for working with this. The BQ25756 needs all 4 switching FETs to operate.

For buck-only mode, the customer will need to use the BQ25820.

Best Regards,
Ethan Galloway
