This chip using USB only like a power supply. You can use it with any 5V stable DC current sources for charge li-ion batteries. If you need an example of use this chip, I will post a part of my project where I used it for a li-ion battery from mobile phone.
This chip provides a stable current on deep recharge phase and then stable voltage on 4.1 level for fully and save charge.
The charging current is adjusted with resistor. I tried to use it with 350mA current - and it works. I afraid to overheat it, but it stays cool all the time.
