Title: LiFePO4 charger (ADP5063) used with a Li-Pol battery
Post by: DanioIO on August 31, 2014, 05:23:17 pm

Hi,
I have a couple of ADP5063 ic and i want to make a charger for my Li-Pol batteries can i use this ic safely? I will need to change the charging termination voltage to 4.2V but this ic allows it so are there any other stuff to consider?

Interesting chip.

I'm just learning about this stuff myself. The thing that caught my eye is that you'll probably want to adjust the current thresholds for Iend. I think the typical guidance is to terminate charging when current drops to 1/10th of the constant-current phase charging rate. It looks like this chip configures those parameters independently from each other, and the default termination current is less than 10% of the default CC rate.

Hmm, now im thinking about blowing a Li-Pol battery with this ic i wonder if its possible...
