Lithium Polymer Battery USB Charger
Finally I’ve finished this project. It’s a USB Charger for Lithium Polymer Battery, that’s very compact and high powerful batteries that I use in most of my projects.
In my recent GUI Bot project I’ve used the famous MAX1555, a greatest IC in a tiny SOT23 package. One thing about MAX1555 that I don’t like is the current limitation it has (about 100mA). I know it’s for USB low speed compatibility, but who knows someone that don’t have a high speed USB host surround? Because that I use the greatest MAX1811. It’s a great IC too, but can deliver up to 500mA! See one of my first post to check more details.
That’s the finished work:
