Part Number: BQ24074

Tool/software:

Hello, 

I am currently working on an hand held device that can be powered by either an external connector, or trough a single rechargeable battery AA. 

I ve been reading a lot, datasheets and discussions. My concern is related to this topic - LINK


Designing with rechargeable and non rechargeable batteries. How can we detect if a battery can be recharged or not?


Thanks in advance for any help you can provide regarding this matter.

    Hi Nelson, 

    Thank you for reaching out via E2E. The statement made by Jeff in the linked topic remains accurate. TI charger ICs do not have the ability to detect whether a connected battery is rechargeable verse non rechargeable. That determination will need to be made by external components rather than the BQ24074 charger IC. 

    Best Regards,

    Garrett
