USB Battery Charger for Lithium Ion Battery circuit diagram

This schematic diagram is used for charging lithium ion battery. The power source is from a computer's USB port. With this circuit, you do not need to build power supply circuits for charging your battery.

A USB port is a great power source for charging a single cell li-on battery. It is capable of supplying maximum 5.25V and 500 mA. The circuit above is a USB powered single cell li-on battery charger. LM3622 is used as the controller. This special purpose IC has a precise end-of-charge control and low battery leakage current about 200nA.
Make Your Own Printed Circuit Boards
Make a PCB in very easy steps..! Create your PCB design using PCB designer software like Eagle, print out your design on photo paper or glossy paper with laserjet printer. Stick the printed design on the PCB (copper side) and then heat it using hot iron plate. The ink will stick on the PCB and it will be ready for etching process.
Watch this video detailed steps:


Note: If you don't have laserjet printer, then you can print the design on standard paper. Copy the printed design at Copy Service around your location (with glossy paper).
