Part Number: BQ25505
Other Parts Discussed in Thread: BQ25570,

Hi Experts,

We would like to ask if the BQ25505RGRT charger IC does support battery rated 1.5 to 2.7V.
Is it possible for this rechargeable rating?

Thank you.

Hi Archie,

BQ25505 cannot be set for constant voltage less than 2.1V, which is the undervoltage setting. Some customers get around this by using BQ25570 and connecting the battery to the buck converter output.

Regards,

Jeff
