Hi All,

We are looking for a charger which can charge 1.5V (20mAh) battery? Are there any charger ICs which can support?

Thanks,

Hello Mahesh,

Could you give a little bit more information about your application.

What cell chemistry are you hoping to use?

What is your input charging voltage?

Switch-mode or linear topology?

Hi Ryan,

Chemistry : Zinc Polymer

Cell voltage: 1.5V (20mAh)

We would like to try both Linear and Switch mode.

We don't have information about the input charging voltage yet.

Thanks,

Mahesh

Hello Mahesh,

TI does not have any chargers that are explicitly for that chemistry primarily because it is so new. Do you have a battery datasheet that you can share to discusses charging profile to see if another charger could possibly be re-purpose?

Hi Ryan,

No problem. I will share more details about the battery once I get it. Thank you.
