I am evaluating the MP2723 charger for use in a future product and am having trouble with the development kit. I cannot make it charge faster than 500 mA, and note that whenever I set ICC, it gets reset to 500 mA on the next read. Additionally, the IINPPM indicator is red, but reviewing the datasheet I cannot figure out what that actually means.
This occurs with two different cell phone chargers and a bench power supply. I have no load on VSYS and am using 3 mostly discharged (3.3 v OCV) 18650s in parallel as a battery.
What does IINPPM mean?
What conditions must I meet to make the MP2723 charge at 3 amps?
