BQ25703A: Can BQ25703A support LTO battery charger?

Hi Eddie,

BQ25703A is not a LDO based charger and cannot be used as an non-switching LDO type charger.

On TI.com, you can select this parameter to search for linear type charger:

Hi Peng,

Thanks, our question is to support LTO (lithium titanate) battery charger, please refer to previously link. 

I think charger voltage can be adjusted from host through I2C, but can we support charger profile for LTO battery?

Thanks & Regards

Hi Eddie,

I misread the title and I apologize.

Is this for a single cell LTO application? The charge voltage can be adjusted through I2C, but the charger has a current clamp of 384mA at voltage <3V.

BQ25703A is an I2C part but has no MPPT feature. It needs CPU processing at all time (cannot work standalone) so it can support any charge profile with CPU control.

Thanks and I hope this helps,

Peng
