Hi Team,

Just want to check if below charging can be achieved.

turn on BATFET and turn off boost FETs. Then battery is charging just through a load switch.

Thanks.

Hi Given,

Charge current is regulated by controlling the buck converter duty cycle. The switch logic does not allow for battery charging through the BATFET.

Hi Jeff,

Thanks.

Then is there solution similar with BQ25870 but for multi-cell battery? Thanks.

Hi Given,

I am not aware of a multi-cell flash charger IC.
