Li-Polymer vs Li-ion polymer and a solution for charging and monitoring the battery

Hi!

We are using a Li-Polymer battery and are searching for a fully integrated solution (monitoring, protection and charging) such as ADP5360, the problem with this IC is it's BAT_CAP limitation to 254mAh (we use a 950mAh battery) and so the displayed SOC is not accurate. I searched on Analog's site in Battery Management and PMIC subcategories for Li-Polymer compatible ICs, but besides ADP5360, found none.

I stumbled upon the ADP5350 IC, but this does not appear in Li-Polymer category, but when I've read the datasheet I found under Applications that is for Rechargeable Li-Ion and Li-Ion polymer battery-powered devices. 

1. Is there a difference between Li-Polymer and Li-ion polymer?

2. Can we use an IC dedicated for Li-ion on our Li-Polymer battery?

3. Could you please provide us with some ICs that are compatible with our battery and have the same functionalities as the ADP5360, such as charging protection and monitoring? http://www.farnell.com/datasheets/1666650.pdf

Thank you,

  • Hi Florin,

    Li-Polymer and Li-ion polymer are same. Li-ion and Li-Polymer battery charging method are also same. As long as parameters of the charger IC can be programmed to match with your battery, it should work.

    ADP5360 is the only battery management IC with protection function. ADP5350 has higher current but without the battery protection. Maybe you can try ADP5061 with 2.9V cut off voltage threshold.
