Hello All,
I am trying to build a single Li-Ion battery charger, and fuel gauge, that is totally standalone. I have 2600mAh batteries that I would like to use with random projects. I am looking at the "BQ24108" as the charger portion, and I would like to use the "BQ34Z100-G1" for the fuel gauge. If I am understanding the datasheet correctly, I HAVE to use the bqStudio to set up the chip for my batteries. That doesn't make any sense to me. I cant spend $199 on a programmer, to use it only once.
So my question is, how can I program the chip without spending an arm and a leg? I do have access to a microprocessor (Parallax Propeller), so I could program the chip, if I knew what registers I needed to change, and what values should be loaded.
Also, I would be willing to change my ideas if someone might have a better option. The requirements I personally have are
- status display (charging, charged, remaining battery level, and (optional) battery charge capacity)
- able to be charged from a USB (PC, and phone charger)
- no BGA packages (I use OSHpark for my boards)
- completely standalone (no host needed to run, but OK for first setup)
Thank you for any advice anyone offers
Anthony
