TPS63061: Vin rating compared to number of cells to be used

Gabor Szoke

Part Number: TPS63061

Dear Team

The following question came from our partner:

We are using in our design TPS63061 in a system with up to 8 batteries. Can you clarify why it is stated in a datasheet that it is intended for three-cell up to six-cell batteries if the input voltage is up to 12V (which would in theory allow eight 1.5V alkaline cells).

Kind regards
Gabor

Hi Julian

I had to edit the post due to the sensitivity of the topic.
Please could you respond to the question, what is limiting functionality to 6 cells while in theory the maximum voltage rating could allow 8 times 1.5V cells to be connected?

Thanks and Regards
Gabor

Hello Gabor,

between 10V to 12V VIN the output load should be limited to 1A max.

Julian

Hello Gabor,

We haven’t heard back so we're assuming you were able to resolve your issue. If not, just post a reply below, or create a new thread if the thread has locked due to time-out.
