BQ24232: BQ24232RGTT - Can it be used to charge a Li-Po Battery

Part Number: BQ24232

Hello,

In a design I have we are using the BQ24232RGTT, to charge a Lithium-Polymer Battery, it has the right characteristics, e.g charges to 4.2V and allows for the correct charging current for the battery we have in mind. However, I'm uncertain if it can be used with the a Lithium Polymer battery chemistry the BQ24232 page from the TI website suggets it can, (URL: https://www.ti.com/product/BQ24232), giving the battery chemistry as both Li-ion and Li-Po.

However, the datasheet for the BQ24232 doesn't mention Lithium-Polymer batteries but only Li-Ion, (URL:https://www.ti.com/lit/ds/symlink/bq24232.pdf?ts=1684834194764&ref_url=https%253A%252F%252Fwww.ti.com%252Fproduct%252FBQ24232%253FkeyMatch%253DBQ24232RGTT%2526tisearch%253Dsearch-everything%2526usecase%253DOPN), and so does the seller of the part Mouser, (URL: https://www.mouser.co.uk/ProductDetail/Texas-Instruments/BQ24232RGTT?qs=drm0CCHqiV6zfY%252BKVPM80Q%3D%3D).

Is the BQ24232RGTT able to be used to charge Lithium Polymer batteries?

Many thanks for your help regarding this query, apologies for any inconvenience.

  • Hi,

    Yes, Li-Ion and Li-Po cells have the same charge profile. If the BQ24232 matches the right characteristics as specified by the battery manufacturer it should be able to charge your Li-Po cells as well.
