Creating Charger from USB Port Computer

Creating Charger from USB Port Computer | The USB port is indeed one of the most useful ports. Besides being used as an interface port for a device I / O computer, it turns out this port can be used as a Li-On Battery Charger (Li-On Battery Charger). The series of Li-On Battery Charger can you see in the image below :

note : The USB port can supply a maximum voltage of 5.25 V with a maximum flow of 0.5 A. Therefore the circuit above can only be used to fill a Li-On Battery only. As IC LM3622 controller is used. The main function of the IC is as final arbiter and as battery charging.
