Part Number: BQ25155

Hi Team,

Can we connect  VIO to LS/LDO as LDO? My customer  want to set VIO 3.0V. 


Regards,

    Hi Shoo,

    Yes, the VIO should be connected to the voltage rail that powers your host controller in order to level shift the digital signals of the BQ25155. If it is powered off the LSLDO rail then connecting to this rail should be fine.

    Best Regards,
